The paper presents the results of experimental research on deposition of wear-resistant chrome-diffusive coatings on the rocker arm shaft support in the process of shell molding. When liquid metal contacts saturated media, on the surface of the form the chrome-carbide diffusive layer 80... 120 mcm. thick with high wear-resistant characteristics being generated. The actual tests of the rocker arm shaft support with the mentioned coating showed that it exceeds at 2,5 times in wearing capacity the current models. The diffusive hardening technology is adopted for implementation at the manufacturing plant.
