Abstract

We presented the results of a study of the substrate temperature effect on the adhesion properties of yttria-stabilized zirconia (YSZ) coatings deposited using a forevacuum plasma-cathode electron source. The adhesion strength parameters were tested with a Revetest RST Macro Scratch tester using the scratch technique. Tests were conducted gradually increasing the load from 0.5 to 100 N at a rate of 2 mm/min and a length of 3–5 mm. The value of the critical load was used to determine the adhesion strength in the coating-substrate system by measuring the applied normal load, the indenter penetration depth, acoustic emission, and the coefficient of friction. Scanning electron microscopy was employed to visualize the indenter track and coating failure. The composition of coatings and chipped area were analysed using the energy-dispersive method. It has been established that the upper value of the critical load significantly increases from 5 to 81 N as the substrate temperature increases from 197to 1050°C.

前真空下不同温度下电子束等离子体沉积钇稳定氧化锆涂层在基底上的附着力

我们研究了衬底温度对前真空等离子体阴极电子源沉积氧化钇稳定氧化锆（YSZ）涂层粘附性能的影响。使用revtest RST宏观划痕测试仪，采用划痕技术测试了粘接强度参数。试验以2 mm/min的速率，将载荷从0.5 N逐渐增加到100 N，长度为3-5 mm。临界载荷的值通过测量施加的法向载荷、压头穿透深度、声发射和摩擦系数来确定涂层-基体系统的粘附强度。采用扫描电镜观察压头轨迹和涂层失效情况。用能量色散法分析了涂层的组成和切屑面积。当衬底温度从197℃升高到1050℃时，临界载荷的上限值从5 N显著增加到81 N。
