The piston surface modification technology is a thermochemical aftertreatment, which prepares piston surface for burn-in coverings and oxide film growing. Modified surface increases scuffing specific load, reducing probability of failures during burn-in stage and under extreme conditions.

Antiscaling covering is a special thermosetting film which based on organic materials. It protects work surface of piston head from free flames in liners, increasing thermo-fatige life of combustion chamber. Antiscaling covering prevents appearance of combustion products scurfs on the piston surface and reduces heat flow into the piston.
