The friction and sliding surfaces of joint machine parts are constituted in their original condition by sharp tops and holes full of wear products and lubricate. When the mechanism is in operation, the friction surface get into a mutual contact.
The sharp tops of the microrelief collide with each other and tear the oil films.

The tops get broken, which results metal particles (i.e. wear products) getting to the lubricant.
In the contact spot, small flashes (sparks) occur resulting in local high temperatures and lubricant destruction, the products of which are also dirt.
As the mechanism operates further, more friction act take place and more tops are broken, and even more wear products and other dirt get into the lubricant.

The RVS compound particles are relatively large in comparison with the tops and holes of the surface (microrelief).
The tops mill, however, the RVS compound particles as mill stones. The temperature increases and a micrometallurgic reaction begins, getting its energy from the heat caused by friction.

In the contact spots, the temperature increases up the level of 900 - 1400°C (~1650 - 2550 °F), which leads to a chemical reaction that is something like a metal melting process in amicroscopic scale.
All this takes place due to the catalysts incorporated in the RVS compound. This is the very know-how of Oy RVS Technology Ltd.
New ferrosilicate (i.e. metalceramic) crystals are formed.

As the process goes on, a deep cleaning process starts and the dirt stuck in the holes of the friction surface is removed to the lubricant.
If the oil is very dirty, it has to be replaced. Otherwise the removed dirt can get back to the holes and prevent the ferrosilicate structure formation.

If the cleaning process is carried out in the way it is supposed to be, one can notice changes in the operation of the equipment being treated even within an hour.
The process goes on and the ferrosilicate structure rises over the level of the original metal surface, i.e. compensated wear.

The thickness of the new surface structure can never exceed the optimal level. It is directly connected with the mass of the RVS compound particles participating in the process and the heat energy available on the friction surfaces. When the friction level and heat extraction are low enough, the growing process ceases automatically.
