What are the different testing methods for Vickers hardness testers?

Taiwan Nakazawa introduces to you that Vickers hardness tester testing is mainly used for material research and scientific experiments. Small-load Vickers hardness testing is primarily used for testing the hardness of small precision parts, surface hardened layer hardness and effective hardened layer depth, surface hardness of coatings, hardness of thin sheet materials and fine wires, hardness near knife edges, hardness of dental materials, etc. Since the test force is very small and the indentation is also very small, the appearance and service performance of the specimen can remain unaffected.
Vickers hardness testers are subdivided into two types of tests based on the magnitude of the test force:
1. Vickers hardness test.
2. Micro-Vickers hardness test.
The choice of test force depends on the type of specimen, specimen thickness, and the expected hardness range.
