Applying XADO Technology

I. Fields of Application

XADO technology works effectively across every sector of the economy and in defense.

• It applies to transport by water, road, rail and air.
• To industry, construction, agriculture and fisheries of all kinds.
• To the mechanical equipment and vehicles that serve everyday household life.

II. Scope of Application

Every technology has a range within which it works well and is recommended for use, and we can call this range the necessary and sufficient conditions for applying the technology effectively. XADO is no exception. For XADO, those conditions are as follows:

• The friction pair must be metal against metal, with at least one side made of ferrous metal.
• The level of wear must be below 100%.
• There must be no mechanical damage to the parts, meaning no seizing, breakage, cracks, chips, pitting or deep scoring.
• The friction system must be strong enough.
• The right amount of XADO must be present in the contact zone between the two metal surfaces.
• The machine must run for the required length of time.

A few further points are worth keeping in mind.

• XADO restores the geometric dimensions well and increases the durability of parts made of ferrous metals and alloys, those containing iron; with non-ferrous parts it still raises durability but restores geometry only slightly, and in practice the great majority of mechanical components are made from ferrous metals and alloys anyway.
• XADO has no effect on non-metallic parts.
• It should not be used in lubrication systems that rely on porous impregnation, nor in mechanisms that depend on the friction effect to function.
• Ít is compatible with every type of oil and grease, neither acting on them nor altering their properties, so it can be used together with any lubricant.

Let us agree, then, that XADO should only be applied to machinery that meets the necessary and sufficient conditions above. Any assessment of how well the technology performs must likewise rest on correct application within that scope and on following the XADO usage procedure exactly.

Whenever XADO is used on machinery, three things happen at the same time: restoration where wear has already occurred, surface strengthening, and optimization of the assembly clearances. This is an extremely important and valuable characteristic of the compound. Understood and analyzed closely, it is easy to see that this property is what makes XADO’s field of application so vast, and what allows us to devise so many engineering solutions in the mechanical field.

III. Ways to Apply XADO Technology

XADO can be used on machinery from the moment it is being manufactured, when it first goes into service, or while it is running with wear below 100%, and it can be reapplied many times over the machine’s lifetime. With XADO, parts made from ordinary mechanical metals can be turned into components of exceptionally high quality at low cost. Depending on the purpose and the timing, there are three broad approaches.

1. As a method of surface strengthening to raise precision and quality

Quality accounts for a large share of the price of mechanical equipment. Two bearings of the same size, for instance, can differ several times over in price from one maker to another. These days, the ordinary mechanical materials in common use are no longer the problem; the crux is the manufacturing technology, the precision and the strengthening method, and here the gap between makers is wide, especially in strengthening. High durability demands advanced technology, modern equipment and heavy investment, and many technological secrets are never licensed out. Quality makes up an ever-larger proportion of cost, and Vietnam’s machine-building industry is falling behind in the quality competition with foreign firms.

XADO technology is the key to solving the strengthening problem at a high level, that is, to raising the quality and value of a product at a fraction of the cost of the conventional approach.

The machines suited to this approach are those still on the assembly line, brand-new machines, machines that have just finished running-in, or machines roughly 10 to 20% into their first working cycle. These have either no wear or very little. It is especially valuable for machinery built on lower-grade production lines with weak strengthening and low precision.

For firms that build and assemble machines, this approach is a way to upgrade their technology and create a new, higher-quality generation of products at very low investment, the cost being simply that of buying XADO. In essence, it adds a XADO treatment step before final inspection and shipment.

A concrete example makes this clear. If you manufacture internal combustion engines, what would you do to bring your cylinders up to the super-durable class? You would have to use special alloys, high-tech ceramics or cermets, or some particular strengthening method that is not XADO. It can be done, of course, but at great expense. With XADO it is simple: no special materials or equipment to buy, just a few tens of thousands of dong worth of XADO for a 400cc cylinder, a couple of minutes to apply it, and then you run the engine as normal. Your cylinder becomes ceramic-metal coated and joins the super-durable class. In fact, XADO Vietnam has been supplying XADO to a number of motorcycle assemblers in the south to upgrade quality, sharply reduce noise and vibration, and increase durability.

For machinery already built with good technology, XADO both improves durability and increases assembly precision, so that the technical specifications reach their design values, and some even exceed them. In one trial, applying XADO to a new, good-quality DS60 engine from VINAPPRO still raised output by 5 to 10% to its design figure and increased durability to the point where it could be test-run with no oil for hours. See the “Reference Materials” section for more.

Machinery built by strong industrial groups is usually made to very high precision and is well strengthened, so it does not necessarily need treatment while new or nearly new. For machines of this kind, XADO is best applied at the first scheduled preventive overhaul, or after 50 to 70% of the first working cycle, as described in point 2 below.

2. As a method of preventive maintenance and repair

This approach suits machinery whose wear is still moderate, below 50%, as well as machines that have just had a major overhaul. Even a freshly overhauled machine still contains parts that are worn but not yet worn enough to need restoring or replacing, meaning some degree of wear remains, which places it in this category.

Here, preventive maintenance and restorative repair are carried out at the same time, which is why it is called preventive maintenance and repair. When XADO is used on machines like these, the worn areas are coated with a ceramic-metal layer, the assembly clearances readily return to their optimal values, performance is restored to as-new condition, and durability rises two to three times over. Because the wear is not yet severe, the chances of a good result are very high.

In developed countries, great emphasis is placed on preventive maintenance and repair as an important way to raise productivity and cut costs, which keeps machinery running in good condition; rarely is a machine run until it fails before being repaired. We have all used plenty of second-hand equipment imported from Japan and Korea and found it still in good shape. It takes little analysis to see that doing preventive maintenance and repair well makes excellent economic sense.

3. As a method of restorative repair

This approach is for machinery with wear from over 50% up to 100%, which we can divide further by degree of wear.

The first case covers machines with relatively high to high wear, in the 50 to 70% range, where results are very good: at the standard dose, wear is made up, performance is restored to as-new condition, and durability rises two to three times over.

The second case covers machines with heavy wear, from over 70% up to 100%, a situation often encountered in Vietnam. Here XADO should be used at a reinforced dose of 1.5 to 2 times the standard, with good results, and in some cases it needs to be combined with conventional repair methods to achieve them.

We know that running machinery with heavy wear means low efficiency and poor economics, and can easily lead to serious damage and breakdown. The XADO approach sets out to carry out repair before wear reaches 100%, heading off serious deterioration in advance and making a good outcome easier for the user. After XADO treatment, the failure-free service interval increases two to three times, and the other benefits XADO brings quickly offset the cost. Understanding and applying XADO technology correctly is a sound way to help a business raise its profits.

IV. The State of XADO Technology in Use

Around the world

In the industrially developed countries, XADO technology has been taken up and put to use quite quickly, thanks to how simple it is to apply and how strong its economic payoff is. Using cermet materials to build high-end machinery has long been a development goal for many large industrial groups, but few such products reach the open market, simply because making cermet parts by conventional metallurgy is far too expensive. XADO now offers an elegant solution: the XADO compound plus the friction of normal operation creates the cermet exactly where it is needed, a very simple and economical answer. Whatever technology delivers good results gets adopted, and today XADO products are in use in nearly all the leading industrial nations.

In Vietnam

Bringing a new technology into widespread use in Vietnam is a hard road. Inertia and a slowness to change hold many people and organizations back, and unless this well-worn mistake is corrected, the technological gap will only widen further. Recently, though, a number of organizations have come to appreciate XADO’s strong economic benefits and have begun using it more widely, and the number of customers using XADO for motorcycles is climbing fairly fast. Through real-world use, consumers will gradually come to understand the technology’s worth. On the whole, there is still much to do before XADO technology is adopted broadly across Vietnam.
