As a high-performance engineering plastic, PEEK has excellent performance in wear resistance, which is one of the reasons why it is widely used in aviation, automobiles, medical, electronics and other fields. Here are some PEEK wear resistance test methods: 1. Wear test: Commonly used wear test methods include sliding wear test, rolling wear test and abrasive erosion test. Among them, sliding wear test is one of the most commonly used methods. Its principle is to use a wear machine to perform linear motion between stressed objects to detect the wear resistance of materials. 2. Friction and wear test: Friction and wear test is a test method that can simulate actual use conditions. It can measure the wear resistance of materials in friction. Common friction and wear test methods include ball-disk friction and wear test and ring friction and wear test. 3. Microstructure analysis: After long-term use, PEEK will produce microstructural changes due to friction, and these changes will affect its wear resistance. T

The friction data of PEEK materials are related to specific situations. The following are the friction data of some common PEEK materials for reference: 1. Friction coefficient between PEEK and steel: The static friction coefficient between PEEK and steel is approximately between 0.3-0.4, and the kinetic friction coefficient Approximately between 0.2-0.3. 2. Friction coefficient between PEEK and copper: The static friction coefficient between PEEK and copper is about 0.4-0.5, and the kinetic friction coefficient is about 0.2-0.3. 3. Friction coefficient between PEEK and aluminum: The static friction coefficient between PEEK and aluminum is about 0.3-0.4, and the kinetic friction coefficient is about 0.1-0.2. It should be noted that the friction coefficient of PEEK materials is affected by many factors, such as material surface treatment, temperature, pressure, lubrication, etc. Therefore, in practical applications, corresponding testing and evaluation need to be carried out according to specific circumstanc
