滑动摩擦磨损试验仪的影响因素：

影响摩擦磨损试验机的摩擦系数的因素有很多，如表面粗糙度、温度、负荷、速度等，不同材料效果不同，下面简要介绍一下这些因素对橡胶、塑料的影响：

塑料摩擦磨耗的影响因素

1.表面粗糙度的影响：接触表面越粗糙，摩擦系数越大

2.温度的影响：温度对摩擦系数的影响不大

3.负荷的影响：随负荷的增大而缓慢下降

4.速度的影响：中/低速，摩擦系数随速度的增加而增大，高速下，滑动摩擦系数随温度的增加而降低

5.配对材料：与不同材料配对时，其摩擦系数有很大差别

橡胶摩擦磨耗的影响因素

橡胶的磨耗主要有三种形式：

1.磨损磨耗：粗糙表面上凸出的尖锐粗糙物不断切割，刮擦

2.疲劳磨耗：硫化胶表面受周期性压缩，剪切，拉伸等形变作用

3.卷曲磨耗：光滑表面接触时硫化胶表面的微凹凸不平的地方发生变形。

影响因素：

实际接触面积的影响：

1.粘附阻力的大小与两表面的微观接触面积的总和成比例

2.在一定温度下，随着负荷的增加而产生的橡胶变形使橡胶与摩擦表面的粘结密度增加，从而使摩擦力增加

温度和速度的影响

1.橡胶的摩擦性能具有明显的粘弹特征

2.摩擦系数是温度和速度的函数，在某一速度和温度下出现极大值

3.磨耗，一般来说，温度升高会使磨耗量增大，随着温度的降低，在玻璃化温度附近，磨耗量达到最小值，然后重新上升。

表面状态的影响

摩擦表面粗糙程度。润滑剂的存在，磨损碎片，橡胶表面老化和环境湿度都会大大改变橡胶的摩擦性能

1.表面状态不同时，摩擦的粘附成分变化明显，特别是有润滑剂时，粘附摩擦成分显著减少。

2.润滑和在橡胶制品表面涂有低摩擦系数的塑料，可以使摩擦系数减小，增大疲劳磨耗的成分，从而使磨耗减少。

环境的影响

周围的气体，液体，湿度对磨耗性能的影响是很大的

1.氧气的存在对疲劳磨耗影响 ，但对粗糙表面上的磨耗影响不大

2.液体介质使橡胶溶胀，从而降低耐磨性
