The Relationship between Coating Property and Solid Particle Erosion Resistance of AIP-Deposited TiAlN Coatings with Different Al Contents

TiAlN coatings with different Al ratios were deposited by the cathodic arc ion plating (AIP) method, and relationship between solid particle erosion resistance structural, mechanical properties was investigated a micro slurry-jet (MSE) test. The crystal structure of coating changes depending on ratio. shows B1 single cubic phase ratio 0 0.58; above this ratio, formation B4 hexagonal is observed. such as hardness Young’s modulus also depend structure. rate decreases increasing up to 0.58, phase. lowest at an 0.58. increases drastically crystalline from more than change in discussed connection erodent
