Abstract

The process of nitriding (the nitride layer and disability) to applied to the electronic components (hardware) besides the automotive components applied, but nowadays there are still gain no optimum result. The research of the atom diffusivity homogeneity effect to the mechanical character into the mechanical surface are yet to be done. And the factor which is affecting like the composition of the elements in the materials are needed to be done an observation. In this research we used some tool steel materials with a different chemical composition, in 550 0C nitriding temperature process in 4 hours to identify the white layer which is formed on the surface and connected with their mechanical characters. The result showed that the value of the hardness materials are very affected by the stability or the homogeneity of the white layer formed in the surface. And the homogeneity is very affected by the composition elements which is contained the materials. The highest hardness level (975.5 HV) is resulted by the AISI P20 with the most homogeneity thickness surface with the most Chrom composition of 2%. The next hardness level is the AISI 4340 (751.2 HV) steel, with 1.4 % Cr composition and the lowest composition is the AISI 4140 (720.8 HV) with 1.07% Chrom.
