Hardness test focuses on the capacity of an object to resist the infiltration of another object with a certain degree of resistance. The minimal the damage caused, the harder the object appears. Human hands can sense the hardness of materials. However, only soft objects can be assessed their hardness by fingers. The testing of technically much harder materials is only possible by the use of testing apparatus. Hardness testing methods The test for hardness of objects is of tremendous importance for quality assurance in industries. The most common methods used are, Rockwell, Vickers, Brinell and Knoop. Rockwell test is the most widely used method of hardness testing. This test is popular as it takes the least time to execute, the machine is affordable and the procedure can be automated. According…
