塑料摩擦磨耗的影響因素

1.表面粗糙度的影響：接觸表面越粗糙，摩擦系數越大

2.溫度的影響：溫度對摩擦系數的影響不大

3.負荷的影響：隨負荷的增大而緩慢下降

4.速度的影響：中/低速，摩擦系數隨速度的增加而增大，高速下，滑動摩擦系數隨溫度的增加而降低

5.配對材料：與不同材料配對時，其摩擦系數有很大差別

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

溫度和速度的影響

1.橡膠的摩擦性能具有明顯的粘彈特征

2.摩擦系數是溫度和速度的函數，在某一速度和溫度下出現極大值

3.磨耗，一般來說，溫度升高會使磨耗量增大，隨著溫度的降低，在玻璃化溫度附近，磨耗量達到最小值，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.

環境的影響

周圍的氣體，液體，濕度對磨耗性能的影響是很大的

1.氧氣的存在對疲勞磨耗影響最大，但對粗糙表面上的磨耗影響不大

2.液體介質使橡膠溶脹，從而降低耐磨性

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
