| description | The nitriding performed to change the chemical composition of the surface is the method of a thermochemical surface hardening. Fine, hard nitrided case consist of two zones at the surface; The outer one white layer (compound layer), the inner one diffusion layer. The nitriding methods are determined at three groups as gas, salt and ion nitriding. Gas nitriding process is performed using ammonia. The nitrogen decompositing from the ammonia gas reacts with the iron and the alloy elements of the steel and nitrides that ensure have fine grain. Salt nitriding is performed at the salt bath that consists of NaCN. Part of the nitrogen and carbon of the siyanide is diffused to the steel. The structure consists not only of nitride but also ?-carbonitride. A gas mixture of nitrogen and hidrogen is usually used in the ion nitriding process. The nitrogen reacts with the iron and alloy elements of the steel and nitrides that ensure hardening exist. In this study, X40CrMoV51 hot work tool steel is used. First, the quenching and tempering, later the ion nitriding is performed to the steel. Then, hardness values and X-ray diffraction analyses of these steels are determined. It is found that the surface hardness of ion nitrided steel is approximately twice higher than that of quenched and tempered steel. |
