FORMATION TECHNOLOGY OF PROTECTIVE AND STRENGTHENING COATINGS ON THE BASE OF DIAMONDLIKE CARBON FILMS

Gomel State University
named after F.Skaryna
Address: 104, Sovetskaja str., 246019, Gomel,
Republic of Belarus


Purpose and area of application

   The technology is intended for hardening machine units working under loading at raised temperatures, in friction pairs for increase of their durability and decrease of friction constant. It can be used at manufacturing diamond tool. The technology is based on laser dispersion and ion-beam synthesis of graphite in vacuum. 

   It can be used for usage in mechanical engineering and tool production.


Technical characteristics
