Tribotechnical, physical-mechanical properties and thermal stability of nano- and micro-composite coatings based on Ti-Al-N

Abstract

In the brief review the results of researches of nanocomposite combined coatings on the basis Ti-AlN/Ti-N/Al2O3 are presented. With the help of methods: auge-electron microscopy, nuclear reactions, rutherford back-scattering of ions, X-ray dispersion microanalysis, scanning electron microscopy, X-ray phase analysis XRD, optical microscopy, nano- and microhardness, wear tests under the scheme the cylinder-plane and also corrosion tests and thermal annealing on air up to 900 °С was shown that these coatings have high physical-mechanical protective properties. It was demonstrated that these multi-layer coatings can be used as for protection against external effects (hardness, wearing, corrosion, temperature) and for recovery of the size of worn-out parts operating in industry.
