Full Article:

The P20 steel, mainly used in plastic molds, was thermochemical treated by ion plasma nitriding, solid and gas carburization. In this work, the solid and gas carburization were carried out at 925ºC in four different times. The ion plasma nitriding was performed at 520ºC in three different times. It was observed that the thermochemical treatment increases the microwear resistance of the studied material. The gas carburizing treatment produced a bigger surface microhardness. Longer times of treatment increase effectiveness of thickness layer in all cases. The solid carburization produced larger thickness layer than gas carburization and ion nitriding.
