[Film Properties and Measurements] - Determination of film abrasion resistance

Coating wear resistance measurement is a method to evaluate the stability of coatings during friction and wear. It is mainly used to test the durability and wear resistance of coatings during friction and wear.

Coating film wear resistance measurement is usually tested using a friction test, which can place a coating sample in a friction instrument for multiple friction cycles to test the durability and wear resistance of the coating during friction and wear. During the test, parameters such as load, friction speed, friction medium of the friction instrument can be adjusted to simulate different wear environments. During the test, changes in properties such as appearance, color, adhesion, weight and hardness of the coating sample are detected to evaluate the wear resistance of the coating.

Coating film wear resistance measurement can be used to evaluate the durability and stability of various types of coatings, such as automotive paints, furniture paints, plastic paints, etc. By measuring the performance changes of coatings during friction and wear, the durability and life of coatings can be predicted, providing basic data for formulating coating maintenance and improvement programs.

The test methods for the wear resistance of the coating film generally include the following:

Grinding wheel wear method: Using a special grinding wheel wear test instrument, the standard grinding wheel is applied to the coating surface with a specific pressure and motion trajectory to simulate the wear under real use. Then use a microscope or other equipment to observe the wear of the coating.

Abrasive wear method: Use abrasive particles of specific particle size and shape to wear the coating surface with specific motion trajectories and forces. Then use a microscope or other equipment to observe the wear of the coating.

Pulley Wear Method: Use pulleys of a specific shape and size to wear the coated surface with a specific trajectory and force. Then use a microscope or other equipment to observe the wear of the coating.

Disc Wear Method: Use a disc of a specific shape and size to wear on the surface of the coating with a specific motion trajectory and force. Then use a microscope or other equipment to observe the wear of the coating.

Nanfangchao reminds you that different types of coatings and application fields may require different test methods and standards. In actual testing, appropriate test methods and standards should be selected according to specific conditions to obtain accurate and reliable test results. At the same time, attention should also be paid to the uniformity and repeatability of test conditions to ensure the comparability and reliability of test results.
