Özet

In this study, AISI P20, H13 and D2 steels were pack borided at 900 and 950 °C for retention times of 2, 4 and 6 h. The boride layer thickness values changed depending on the chemical composition of the steels. The hardness of borides that formed on the surface of AISI P20, AISI H13 and AISI D2 steels were 1897 HV(50 g), 1989 HV(50 g) and 1916 HV(50 g), respectively. On the other hand, the Vickers hardness values of the untreated steels were 532 HV(50 g), 485 HV(50 g) and 408 HV(50 g), respectively. The adhesion properties of the boride layer were analyzed by performing the Daimler–Benz Rockwell-C adhesion method. According to the adhesion and wear test results, the adhesion and wear resistance of the boride layer decreased with the increase in the boriding temperature and time.
