金相磨削后, 抛光方法有几种

打磨后, 金相试样需要抛光，以去除试样上磨削过程中产生的磨痕和变形层, 使它成为一面光滑的镜子. 现在, 抛光样品的方法包括机械抛光, 电解抛光, 化学抛光和复合抛光. 1.机械抛光: 在专用抛光机上抛光. 机械抛光主要分为两个步骤: 粗抛和精抛. 粗抛光: 目的是去除抛光变形层. 在...

洛氏硬度计在使用过程中遇到故障有如何解决

洛氏硬度计适用于金属洛氏硬度测试. This test method is characterized by measuring the indentation depth and reading the hardness value of the sample directly on the dial or digital display screen of the hardness tester, which is convenient, simple, rapid and high efficiency. Small indentation, small damage on the working surface of the parts, suitable for batch parts testing; Rockwell hardness test has a wide range. Because the hardness tester is affected by external and...
