Abstract

The structure and tribological characteristics of 1-μm-thick TiAlN-based coatings with soft metal additions (In, Sn, Pb), which are prepared by reactive magnetron sputtering of separated cathodes, are studied. The coatings are found to have a columnar nanocrystalline composite structure. The Al_xTi_{1 –} _xN, In(Sn) solid solution, Pb, and PbO phases are found in the coatings. The microhardness of the coatings is 280–382 HV. Under reciprocating motion conditions at room temperature, the minimum friction coefficient (μ ≈ 0.20) and high stability of tribological characteristics are achieved for a TiAlN–InSn coating with the atomic ratio Al/(Al + Ti) = 0.53. As the test temperature increases to 100 or 200°C, the wear of the coating and the transfer of the counterbody material decrease; which is related to the presence of the Al_xTi_1–xN phase with a wurtzite structure characterized by a low shear strength.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
