摘要(Abstract)：

利用等离子表面合金化技术,在304不锈钢表面制备渗Cu改性层。借助球-盘磨损试验机对改性层常规大气环境下与不同偶件(GCr15球,Al2O3球)对摩时的摩擦学性能进行了测试。结果表明:不锈钢表面渗Cu改性层均匀致密、与基体结合良好,厚度大约26μm,主要由纯Cu和膨胀的奥氏体等相组成。渗Cu改性层的摩擦学性能与摩擦偶件相关。渗Cu不锈钢与GCr15球对摩时Cu改性层阻止了不锈钢与配副直接接触,并在摩擦过程中起到固体润滑作用,明显改善了不锈钢的摩擦学性能;渗Cu不锈钢与Al2O3球对摩时,由于陶瓷球的稳定化学性能及Cu改性层相对较低的剪切强度,导致摩擦过程中磨粒磨损加剧。
