摘    要:用销-盘、单摆冲击划痕和高速刮擦三种试验方法,研究了两种NiCrW-BN封严涂层的可刮削性.结果表明:封严涂层的可刮削性不同于耐磨性,即涂层的磨损量、比能耗和硬度等测量结果,不能单独作为其可刮削性的评价判据;评价封严涂层的可刮削性,应该综合涂层磨损、叶片磨损、摩擦系数和磨痕形貌等多方面的信息.封严涂层的可刮削性能受试验条件的影响十分明显,高速刮擦试验可模拟涂层工作参数(刮擦线速度、入侵速率等),可能重现其磨损现象,因此采用高速刮擦试验方法评价封严涂层的可刮削性更为合理.

关 键 词:复合材料  可刮削性  高速刮擦法  封严涂层  可刮削

Abstract:The abradability of two NiCrW-BN seal coatings processed by different heat treatments were observed by pin-disk,single-pass scratching,and high-speed wear tests.The results show that seal coating abradability is different from its wear-resistance,i.e.measuring of wear loss,wear-resistance, specific energy consumption and hardness,can not be used as abradability criterion.Coating abradability evaluation should be composed of extensive information,such as coating and blade wear loss,friction coefficient,wear ...
Keywords:composites  abradability  high-speed rubbing test  seal coating  abradable
