Abstract
The hardness and frictional coefficients of two-layer coatings are investigated. The coating life of steel samples is investigated on the basis of its elastoplastic deformation and the microhardness before and after testing on a frictional machine. The two-layer Mo2N + Mo coating considerably outperforms the steel in terms of microhardness. The life is greatest for TiC coatings.
