The wear resistance of PEEK material will decrease over time

The wear resistance of PEEK material will decrease over time, mainly due to the following reasons:
-Oxidation: Long term exposure to air and other environments can cause oxidation reactions in PEEK materials, resulting in increased surface roughness and decreased glossiness, which in turn leads to decreased wear resistance
-Physical damage: During use, material surfaces may experience physical damage such as scratches and wear, which can damage the surface structure of the material, exacerbate wear, and accelerate the rate of wear resistance degradation
-Molecular chain breakage: Over prolonged use, the molecular chains inside the material will gradually break, leading to a decrease in its mechanical properties, including hardness, strength, etc., thereby affecting wear resistance
-Chemical corrosion: If subjected to chemical corrosion in a specific chemical environment, the performance of PEEK material will change, thereby reducing its wear resistance
-Temperature effect: Long term use in high-temperature environments can intensify the molecular chain movement of PEEK materials, which may cause changes in the structure and properties of the material, leading to a decrease in wear resistance
-Ultraviolet irradiation: PEEK material is sensitive to ultraviolet radiation, and prolonged exposure to ultraviolet radiation can cause aging, leading to a decrease in performance and ultimately affecting wear resistance
