Introduction to Microhardness: Microhardness is a type of indentation hardness that reflects the ability of the tested object to resist the indentation of another hard object. The measuring instrument is a microhardness tester, which is actually a microscope with a loading device and an eyepiece micrometer. Before measurement, the abrasive to be tested should be made into a reflective grinding disc sample and placed on the stage of the microhardness tester. The diamond indenter with a pyramid shape should be pressurized by a loading device. The magnitude of the load can increase or decrease depending on the hardness of the material being tested. After the diamond indenter is pressed into the sample, a pit will be formed on the surface of the sample. Align the microscope crosshair with the indentation and measure the length of the diagonal of the indentation using an eyepiece micrometer. The microhardness value of the measured substance can be calculated based on the applied load and the diagonal length of the indentation Microhardness testing scope: Steel microhardness, thin gold plating microhardness, pure aluminum microhardness, nanoindentation microhardness, stainless steel microhardness, concrete microhardness, magnesium alloy microhardness, glass microhardness, cementite microhardness, titanium alloy microhardness, carbon steel microhardness, multiphase alloy microhardness, powder microhardness, etc Microhardness testing items: Micro Vickers hardness testing, dynamic microhardness testing, load microhardness testing, high-temperature microhardness testing, metallographic microhardness testing, etc. (For more needs, you can consult laboratory engineers to answer them for you.)

What are the functions of the Baijian.com test report? What problems can I help you solve< p> 1. Sales use. (Selling one's own products and issuing third-party testing reports to make customers more confident in the quality of their products)

2. Research and development for use. During the research and development process, when encountering some challenging problems, we can solve them by testing report data, thereby shortening the research and development cycle and reducing research and development costs. 3. Improve product quality. (By comparing the testing data, identify the problems with one's own product, improve product quality, and reduce production costs)

4. Use of research paper data 5. Bidding, Bidding for use (BAIJIAN has a relatively short testing cycle, low testing cost, high recognition, and is particularly suitable for bidding)
