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

The influencing factors of plastic friction and wear

1. Effect of surface roughness: The rougher the contact surface, the greater the friction coefficient

2. The influence of temperature: Temperature has little effect on the coefficient of friction

3. Impact of load: Slowly decreases with increasing load

4. Impact of speed: At medium/low speeds, the friction coefficient increases with the increase of speed, while at high speeds, the sliding friction coefficient decreases with the increase of temperature

5. Paired materials: When paired with different materials, there is a significant difference in their friction coefficient

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。

The influence of temperature and speed

1. The friction performance of rubber has obvious viscoelastic characteristics

2. The coefficient of friction is a function of temperature and velocity, with a maximum value occurring at a certain velocity and temperature

3. Wear, generally speaking, an increase in temperature will increase the amount of wear. As the temperature decreases, the wear reaches its minimum value near the glass transition temperature and then rises again.

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最大，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

Environmental impact

The influence of surrounding gases, liquids, and humidity on wear performance is significant

The presence of oxygen has the greatest impact on fatigue wear, but has little effect on wear on rough surfaces

2. Liquid media causes rubber to swell, thereby reducing wear resistance
