We study the wear resistance, fatigue strength, and corrosion-fatigue strength of SShKhN-42 rolls made of cast iron with surface nanostructures obtained as a result of mechanical-pulse treatment under the operational conditions of rolls of the rolling mills. It is shown that the surface nanostructure makes the wear resistance of cast iron three times higher and almost doubles the fatigue strength. This type of behavior of cast irons with surface nanostructure is scientifically substantiated.

表面纳米结构对 SShKhN 铸铁轧辊使用性能的影响

我们研究了由铸铁制成的 SShKhN-42 轧辊的耐磨性、疲劳强度和腐蚀疲劳强度，其表面纳米结构是在轧机轧辊运行条件下通过机械脉冲处理获得的。结果表明，表面纳米结构使铸铁的耐磨性提高了三倍，疲劳强度几乎提高了一倍。具有表面纳米结构的铸铁的这种行为是有科学依据的。
