RVS
Technology™ is not just a new method of fighting against wear but
a way of controlling it!
The
friction and sliding surfaces of joint machine parts have sharp tops and deep
gaps full of dirt and metal particles. When the mechanism is in operation, the
friction surfaces make contact. The sharp tops of the edgy surfaces collide
with each other and tear the oil films, which breaks down the oil.
The
sharp tops break, which results in metal and dirt particles mixing in with the
oil. In the contact spots, small flashes (sparks) occur resulting in local high
temperatures and lubricant destruction, which further breaks the oil down. As
the mechanism operates further, more friction takes place and more sharp tops
break, resulting in the pollution and break down of the lubricant.
The
RVS compound particles are relatively large in comparison with the tops and
gaps of the surface (the micro relief). When these sharp tops break, they
serve as a "milling" device for the RVS particles. In the contact spots,
the temperature levels increase to 900 - 1400°C (~1650 - 2550 °F), which
leads to a chemical reaction that can be best described as a metal-melting process
on a microscopic scale, "molding" the RVS particles onto the metal
surfaces. New Ferro silicate (i.e. metal ceramic) crystals are formed. What
makes this reaction possible are the catalysts incorporated into the RVS compound.
This is the very know-how of RVS Technology™.
As
the process goes on, a deep cleaning process starts and the dirt particles
stuck in-between the gaps of the friction surfaces are removed and "thrown out" into
the lubricant. If the oil is very dirty, it has to be replaced (usually after
first treatment, see application
instructions), otherwise the dirt particles can fill up the gaps again and
prevent the Ferro silicate 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 as soon as one
hour after the treatment. The process goes on and the Ferro silicate structure
rises over the level of the original metal surface. Think of it as an ocean
rising to the level of the highest peak in a mountain range, the uneven peaks
vanish beneath the smooth ocean surface.
The
thickness of the new surface structure can never exceed the optimal level.
That is, the "ocean" can never exceed the level of the "highest peak".
It is directly connected with the mass of the RVS compound particles participating
in the process and the heat energy available from the friction surfaces.
When the friction level and heat extraction are low enough, the Ferro silicate
process ceases.
These are the basic properties
of the newly created Ferro silicate surface:
Coefficient of linear thermal expansion:
13.6-14.2
Friction coefficient: 0.003-0.007 (dry
without lubricant)
Micro hardness: 690-710 HV
Shock resistance: 50 kg/mm²
High corrosion resistance
Clear isolating and heat-proof properties
