| 10. | Owing to the interfacial cracking which occurs under higher applied load conditions , the composite with high content of tib _ 2 phase exhibited a transition from mild wear to severe wear over the applied load range from 10 n to 80 n . under moderate applied load , increasing the sliding speed caused a decrease in wear rate and friction coefficient of the in - situ composites because the formation of a protective oxide film occurred on the sliding surface and the hardness of the subsurface layer was maintained due to reinforcement of tib2 nanoparticles in the cu matrix
随着载荷的增加， cu -纳米tib2原位复合材料的磨损率和摩擦系数增加；由于在较高载荷下发生表面开裂，高含量的tib2相增强原位复合材料发生了由轻度磨损向严重磨损形式的转化。在中等载荷下由于表面保护性氧化膜的形成和基体中纳米tib2相的存在使复合材料具有良好的抗软化能力， cu -纳米tib2原位复合材料的磨损率和摩擦系数随着滑动速度的增加而下降。 |
