Brinell Hardness Tester: It uses a cemented carbide ball as the indenter and presses it into the material surface under a relatively large test force. The Brinell hardness value is calculated based on the diameter of the indentation. It is often used to measure softer metal materials, such as annealed copper, aluminum, etc.
Rockwell Hardness Tester: There are multiple scales available, such as HRA, HRB, HRC, etc. It uses a diamond cone or a steel ball as the indenter and determines the Rockwell hardness value according to the depth of the indentation. It is suitable for testing materials with different hardness ranges and is widely applied.
Vickers Hardness Tester: It uses a square - pyramid - shaped diamond indenter and conducts tests under a relatively small test force. The Vickers hardness value is calculated by measuring the length of the diagonal of the indentation. It has high testing accuracy and can be used for hardness testing of various metals and some non - metal materials.
Metal Processing Industry: During the production and processing of metal materials, hardness testers are used to detect the hardness of raw materials, semi - finished products, and finished products to ensure that product quality meets standards. For example, in steel production, the hardness is tested to control the heat treatment process of steel and ensure the performance of steel.
Machinery Manufacturing Industry: It is used to evaluate the hardness of mechanical parts and determine whether they meet the design requirements. For components such as engine parts and gears, accurate hardness measurement is crucial for ensuring the wear resistance, strength, and other properties of the parts.
Aerospace Field: Aerospace materials have extremely high performance requirements. Hardness testers are used to detect the hardness changes of materials under different environmental conditions, providing a basis for material selection and design.
Scientific Research Field: In materials research, hardness testers help researchers study the properties of new materials, explore the relationship between hardness and material structure and composition, and promote the development of materials science.
High Accuracy: It can accurately measure the hardness value of materials, providing reliable data for material performance evaluation.
Easy to Operate: Modern hardness testers usually have a high degree of automation and a user - friendly operation interface. Even non - professionals can operate them proficiently after simple training.
Fast Testing Speed: Hardness testing can be completed in a short time, improving production efficiency and scientific research progress.
Data Traceability: Test results can be recorded and stored, facilitating subsequent query and analysis, and contributing to quality control and product traceability.
In conclusion, hardness testers play an indispensable role in material performance testing. With the continuous development of technology, their performance and functions are constantly improving, providing strong support for the development of various industries.
