Abstract
The erosion, corrosion, and heat resistance of alloy/ion-plasma nanolayer coating compositions based on TiC and CrC carbides and TiN, CrN, ZrN, and AlN nitrides are studied. The effect of the nanolayer thickness, composition, and structure of the coatings based on the metal nitrides and carbides on the relative erosion resistance of alloy/coating compositions in a gas-abrasive quartz sand flux is studied at a sand grain size of 300–350 μm, abrasive supply rate of 200 g/min, and an angle of flux incidence of 20° (tangential flow) and 70° (near-head-on attack flow). It is shown that high erosion resistance is characteristic of 15–22 μm thick coatings that are produced by assisted deposition and consist of alternating TiN (70 nm) and CrN (70 nm) layers on a VT1-0 titanium alloy or TiC (70 nm) and CrC (70 nm) layers on an EP866 compressor steel.
