Abstract

As a result of the studies carried out, the linear wear rate Ih of solid lubricating coatings (TSP) of the diffusion type dimolite (M801) in friction pairs with various counterbodies (D16T, VT3-1, Fe-Pb, Mo, Mo + 30 % MoS2, Mo + 50 % MoS2 , dimolite, graphite) for normal atmospheric conditions. The linear wear rate of the best pairs with dimolite, comparable to the TSP of suspension deposition of VNII NP 212, was Ih = (2.9...5.51) · 10–10 for counterbodies made of Fe-Pb pseudo-alloy, molybdenum, combined materials Mo + MoS2 and dimolite. The best antifriction properties (ffr = 0.02) in a pair with dimolite are found by counterbodies made of D16T, VT3-1, pseudo-alloy Fe-Pb and molybdenum.
