A high Rockwell C rating means the tested steel is high-strength.Any value ranging in the mid-50s and above on the Rockwell C scale is considered hard.Study of the Effect of Gas Nitriding Time on Prior studies have noted that gas nitriding has a considerable effect for wear resistance.The aim of this paper is to study the influence of gas nitriding time (12,24,36 and 48 h) in the wear behaviour of 42CrMo4 steel.It has been assessed by micro hardness,pin-on-disc tribosystem,and SEM through the nitrided layer for each nitriding time.
The value of surface roughness parameter,R a,of the samples before the shot peening had been 0.29 µm,and for the samples after shot peening,the value was in the range from 5.24 to 5.91 µm.The presented data show that the surface roughness parameter,R a,increased by about 20 times after the shot peening process,as compared to the surface roughness in the initial state.Vickers hardness testing insight StruersHardness testing of welds can be performed on any Vickers micro hardness testing machine.When hardness testing of welds,a series of measurements are made in a given pattern at a specific distance from the sample edge or top of the weld.The progression of the hardness values can then be plotted in a graph.Methods typically used HV5 and HV10
