' ' Song typeface tests hardness values. The series of portable Rockwell hardness testers are very suitable for testing the hardness of cemented carbide. The weight accuracy of the instrument is the same as that of the desktop Rockwell hardness tester, and it is very convenient to use and carry.
< ( ' ' Song typeface /> ( ' ' Songti alloy is a kind of metal. The hardness test can reflect the differences in mechanical properties of cemented carbide materials under different chemical compositions, organizational structures and heat treatment process conditions. Therefore, the hardness test is widely used to test the performance of cemented carbide. Supervise the correctness of the heat treatment process and the research of new materials.
< ( ' ' 宋体/> ( ' ' 宋体 Features
< ( ' ' 宋体/> ( ' ' 宋体 It is a non-destructive test test The method is relatively simple. The hardness testing of cemented carbide has strong adaptability to the shape and size of the specimen and high test efficiency. In addition, there is a certain correspondence between the hardness of cemented carbide materials and other physical properties. For example, cemented carbide hardness test The tensile test and the tensile test basically test the ability of the metal to resist plastic deformation. To some extent, both tests test similar properties of the metal. Therefore, the test results are completely comparable to each other. Carbide tensile testing equipment It is bulky, complex to operate, requires sample preparation, and has low test efficiency. For many metal materials, there is a conversion table for hardness test and tensile test. Therefore, when testing the mechanical properties of cemented carbide materials, people are increasingly using hardness tests. Tensile testing is rarely used.
< ( ' ' 宋体/> ( ' ' 宋体Tools
< ( ' ' 宋体/> < ( ' ' 宋体/> ( ' ' 宋体 cemented carbide has average hardness Rockwell hardness tester scale or Vickers hardness tester is used to test. In practice, people mainly use Rockwell hardness tester to test hardness. The series of portable Rockwell hardness testers are very suitable for testing the hardness of cemented carbide. The weight of this instrument is only as accurate as the desktop Rockwell hardness tester. The same as the hardness tester. When measuring the hardness of cemented carbide, the series of portable Rockwell hardness testers produced by Tianxing Company can test cemented carbide workpieces with a thickness or diameter of less than Carbide workpieces. It can also be used at the production site, sales site or material warehouse. This instrument is used to test the carbide workpieces simply, quickly and non-destructively. It can test the hardness of batches of finished or semi-finished carbide workpieces piece by piece. Detection.
