Abstract

The structure and properties of TiN, Ti-Si-N, Ti-Al-Si-N, Ti-Cr-Si-N, Ti-Zr-Si-N, Ti-B-N, Ti-Cr-B-N, and Ti-Si-B-N coatings obtained by reactive electric-arc evaporation and magnetronic sputtering of Ti, TiSi, TiAl, TiCr, TiZr, TiBN, TiCrB, and TiSiB targets are compared. Tests of cutting tools with these coatings in the drilling, turning and milling of steel indicate that the coating increases the tool’s life by a factor of 5–20.
