" Microcomputer-controlled High-temperature Friction Testing Machine "
Main Purposes
The microcomputer - controlled high - temperature friction testing machine is a device specifically designed for testing the frictional properties of materials in high - temperature environments. Its main purposes include, but are not limited to, the following aspects:
Material R & D and Evaluation
- Used to evaluate the friction and wear properties of various materials under high - temperature conditions, including metals, non - metals, coatings, rubbers, plastics, ceramics, etc.
- Helps in the research and development of new high - temperature - resistant materials and improves the high - temperature frictional properties of materials.
Lubricant and Oil Product Testing
- Test the frictional properties of lubricants, hydraulic oils, internal combustion engine oils, gear oils, etc. at high temperatures, and evaluate their lubrication effects and anti - wear capabilities. - Provide data support for the R & D, improvement, and quality control of lubricants and oil products.
Durability Testing of Mechanical Components
- Simulate the actual working conditions of mechanical components in high - temperature environments, test their friction and wear properties, and evaluate the durability and reliability of the components. - Contribute to optimizing mechanical designs and improving the service life and performance stability of mechanical components.
Aerospace and Automotive Manufacturing Applications
- Test the frictional properties of aerospace vehicles and automotive components in high - temperature environments to ensure their reliability and safety under extreme conditions. - Provide a basis for material selection, performance optimization, and quality control in the aerospace and automotive manufacturing industries.
Applicable Standards
When conducting tests, the microcomputer - controlled high - temperature friction testing machine usually needs to comply with the following relevant national or international standards: - GB/T series standards: Relevant regulations on friction and wear testing in Chinese national standards, such as GB/T 12583 - 98 *Method for Determination of the Extreme - Pressure Properties of Lubricants (Four - ball Machine Method)*, etc.
