Technology of Reconditioning with Hardening of Working Elements of Construction and Road Machines by Composite Coatings

The article gives the description of developed technology increasing wear resistance working elements national and foreign constructional road machines by composite coatings, obtained on cutting surfaces applying Carbo Vibro Arc Hardening method (CVAH). includes following basic operations: cleaning fault detection element, removal worn compensating element production, its sharpening welding, preparation metal ceramic paste for (CVAH) application, harden surface element. When hardening new technological process operations connected with production welding is not performed. According to carried out results rational composition component concentration that provides significant increase resistance.
