PEEK material has excellent wear resistance, mainly reflected in the following aspects:
-High hardness and strength: PEEK material has high hardness and strength, and its wear resistance far exceeds that of most metal materials and other polymer materials. Under the same working conditions, its wear degree is significantly lower, and it has high application value in harsh working conditions such as wear, friction, and corrosion
-Excellent anti fatigue performance: It has excellent anti fatigue performance, and even under long-term repeated loads, its mechanical properties can still remain stable, making it less prone to fatigue cracks. It has significant advantages in manufacturing parts that require long-term load-bearing, such as bearings and gears
-Low friction coefficient: PEEK material has an extremely low friction coefficient and can maintain good stability even in high-speed motion or poorly lubricated environments. This is of great significance for parts such as bearings and pulleys that require high-speed rotation or sliding
-Good chemical resistance: Excellent chemical resistance enables PEEK to maintain stable physical and mechanical properties in various corrosive media such as acids, alkalis, and salts, and has high reliability in applications in chemical, petroleum, and other industries
-Good high-temperature stability: PEEK material has a melting point of up to 343 ° C and a thermal expansion coefficient of only about 2 × 10 ⁻⁵/° C. It has good mechanical properties and dimensional stability in high-temperature environments and is suitable for the manufacturing of high-temperature components in aerospace and other fields
In addition, by adding substances such as carbon fiber, graphite, PTFE, etc. to modify PEEK, its wear resistance can be further improved
