What Are The Factors That Affect The Vickers Hardness Tester Value?
What are the factors that affect the hardness value of the Vickers hardness tester? This should be analyzed from the test principle and test conditions, specifically the following aspects: 1. Hardness tester: (1) Load mechanism: mainly includes the change of weight weight; the movement condition of the load mechanism; the friction force of the main shaft; the perpendicularity between the main shaft and the worktable; the change of the load lever arm ratio. (2) Indenter: It mainly includes two aspects: the geometric [...]
