HardnessCarbonNon-destructive testingCarbon alloysA test procedure is outlined which permits detection and evaluation of surface decarburization on steel. The procedure consists of making a series of Rockwell hardness tests on the specimen surfaces using several Rockwell test scales. Evaluation of the ...
1.洛氏硬度测试是一种用于测量材料硬度的标准方法,通过测量材料在特定压力下的压痕深度来评估其硬度。 2.ISO6508-2:2015规定了洛氏硬度测试的验证和校准过程,以确保测试设备的准确性和可靠性。这包括了对测试设备和压头进行定期的校准和维护,以确保它们在所有条件下都能提供准确的硬度读数。 3.在进行洛氏硬度测试...
1.1 Rockwell Hardness Testing In a Rockwell hardness test, initially a minor load of 10 N is applied and the zero datum position is established. The major load (60, 100, or 150 N) is then applied for a specific period (a few seconds) and removed, leaving the minor load applied. The ...
