What are the commonly used abrasion tests in the world?

Abrasion test is a test method used to evaluate the wear resistance of materials, which is often used in the research and application of various materials. The commonly used abrasion test methods in the world are as follows:

1. Rolling wear test: The rolling wear test is a test method that simulates the wear of tires when they are running on the road. In the test, the sample is placed on a rotating drum, and the sample is subjected to rolling wear by different loads and speeds. This test method can be used to evaluate the wear resistance of rubber, plastic, metal and other materials.

2. Grinding test: Grinding test is a test method that simulates the wear of materials during use. In the test, the specimen is brought into contact with an abrasive disc, which wears the specimen through different loads and speeds. This test method can be used to evaluate the wear resistance of metals, ceramics, coatings and other materials.

3. Friction and wear test: Friction and wear test is a test method that simulates the wear of materials during friction. In the test, the sample is placed on a friction disc, and the sample is subjected to friction and wear by different loads and speeds. This test method can be used to evaluate the wear resistance of plastics, coatings, rubber and other materials.

4. Rotor-stator test: The rotor-stator test is a test method for simulating the contact wear between turbine blades and stators. In the test, the specimen is placed on a rotating rotor, which wears the specimen through different loads and speeds. This test method can be used to evaluate the wear resistance of metals, ceramics and other materials.

5. Abrasive wear test: Abrasive wear test is a test method that simulates the wear of materials under the action of abrasive particles. In the test, the specimen is brought into contact with abrasive grains, which are abraded by varying loads and speeds. This test method can be used to evaluate the wear resistance of ceramics, metals and other materials.

In a word, wear test is an important test method, which can be used to evaluate the wear resistance of materials and provide reference for the design and production of materials. Different abrasion test methods are suitable for different types of materials and application scenarios, and it is necessary to select the appropriate test method according to the specific situation.
