What is a fully automatic scratch tester?

The automatic scratch tester is an instrument used to evaluate the scratch resistance of the material surface. It can simulate different degrees of scratches in daily use to determine the wear resistance and durability of the material surface. This tester is commonly used in areas such as material research, quality control and product development.

The working principle of the automatic scratch tester is to simulate the scratching process in daily life by applying a certain force and motion trajectory on the surface of the sample. The instrument typically consists of an adjustable loading platform and a moving scraper that scrapes back and forth across the sample surface at a certain speed and pressure. During the scraping process, the instrument will record data such as scratch track, scratch depth and scratch length for subsequent analysis.

The automatic scratch tester can use a variety of standard test methods, including Tabor scratch test, Taber scratch test, Sutherland scratch test and universal material testing machine scratch test, etc. These test methods usually include changing parameters such as blade shape, material hardness, blade load, and blade speed to simulate different scraping environments. By comparing the test data under different test conditions, the scratch performance and wear resistance of the material can be determined.

Fully automatic scratch tester is widely used in the research and development process of various materials, especially in the fields of coatings, plastics, rubber, ceramics, glass and metals. For example, in paint research, fully automatic scratch testers can be used to evaluate the scratch resistance, abrasion resistance and durability of paint surfaces to determine whether the paint meets the requirements of specific applications. In the development of plastic products, the automatic scratch tester can be used to evaluate the surface quality and durability of plastic products to determine whether the plastic products have sufficient durability and durability.

In conclusion, the automatic scratch tester is a very useful testing instrument that can help researchers and engineers of various materials evaluate the wear resistance and durability of materials to determine whether the materials are suitable for specific application fields.
