Revitalization

Revitalization, What is revitalization?



The term "Revitalization" (from Latin "vita" = life) literally means "returning to life". The revitalization process is based on unique physicochemical processes which, under certain conditions, take place in the friction zone.
As soon as a mechanism begins to operate, it starts to wear out. Eventually, something will fail. Under load, the working surfaces of the parts rub, overheat and deform. Metal particles are simply taken away and wiped off the surface. Having lost weight and shape, the part cannot serve properly and fails.


During mechanical operation all machinery parts will experience mechanical stress resulting in friction between any two moving parts, which slowly destroys the structural integrity of the metallic surface.

Let's have a look at the part in the microscope. Even a very smooth surface looks uneven at considerable magnification, looking like a chain of "peaks" and "cavities". Little by little the wear seizes weak places, the "cavities" become deeper and deeper. So, the 100% wear occurs when the "peaks" start wearing down. 
After Treatment
As long as the "peaks", which remember the original size of the part, exist, the part can still be restored by subjecting to revitalization. It follows that the part will never gain in seize more than it should be. As soon as a peak and a cavity match, the energy conditions necessary for revitalization disappear. The system becomes stabilize. And the building material, which is left unused, will come into reaction as soon as the surface gives it warning of appearing of surface's wear.
