The sliding wear and friction behaviour of new developed WC-stainless steel composites without and with carbon addition were evaluated using a linearly reciprocating sliding tribometer under ball-on-flat configuration, sliding against an alumina ball under unlubricated conditions. The wear of both, discs and ball were measured for different applied loads, sliding distances and frequencies. Worn surfaces were investigated by using microscopy and topography techniques. Comparative experiments were performed using flat samples of a conventional WC–Co composite. It was found that the WC–Co grade displayed an undoubtedly better sliding wear resistance and lower coefficient of friction if compared with the newly produced WC-SS composites.

WC-不锈钢和WC-Co复合材料的滑动磨损和摩擦行为

新开发的 WC-不锈钢复合材料的滑动磨损和摩擦行为在没有和没有添加碳的情况下使用线性往复滑动摩擦计在球对平面配置下进行评估，在未润滑条件下对氧化铝球滑动。针对不同的施加载荷、滑动距离和频率测量了盘和球的磨损。通过使用显微镜和形貌技术研究磨损的表面。使用传统 WC-Co 复合材料的扁平样品进行对比实验。结果发现，与新生产的 WC-SS 复合材料相比，WC-Co 牌号无疑具有更好的滑动耐磨性和更低的摩擦系数。
