A relationship between wear behavior and structural-phase state of HSS M2 electron beam cladded coating rubbed against AISI52100 or AISIO7 counterbodies in a range of loads and speeds has been established. When rubbing the coating against the AISIO7 counterbody the wear rate increased with the normal load while coefficient of friction decreased. The effect of the counterbody on wear and friction higher speeds was related to generation of mechanically mixed layers (MMLs) composed of iron tungstate, carbide fragments and transferred metal. Steady wear rate vs. time dependence in M2/AISI O7 pair is due to higher amount of this mixed oxide.

已经建立了在一系列载荷和速度下与 AISI52100 或 AISIO7 配对体摩擦的 HSS M2 电子束熔覆涂层的磨损行为和结构相状态之间的关系。当涂层与 AISIO7 对应体摩擦时，磨损率随正常负载而增加，而摩擦系数降低。配对体对磨损和摩擦更高速度的影响与由钨酸铁、碳化物碎片和转移金属组成的机械混合层 (MML) 的产生有关。M2/AISI O7 对的稳定磨损率与时间相关性是由于这种混合氧化物的含量较高。
