Performance enhancement by novel plasma boron-nitriding for 42CrMo4 steel
Source abstract
Abstract
Abstract In order to further enhance the performance of the components previously treated by plasma nitriding (PN) and meet the technical requirements proposed by the cooperative enterprise, plasma boron-nitriding (PNB) was primarily developed for 42CrMo4 steel at 520 °C for 6 h by adding a little Ferroboron around the samples during the process of plasma nitriding. The results show that plasma boron-nitriding (PNB) can significantly increase the surface hardness of the sample from 750HV0.05 to 1002HV0.05 due to the formation of very hard borides of FeB and Fe2B, and the thickness of compound layer is increased from 18.78um to 29.44um, the effective diffusion layer is increased from 265um to 355um, which is equivalent to an increase of nitriding efficiency by about 35%. At the same time, the wear resistance of the samples treated by PNB is significantly enhanced, the wear marks turns to be much shallower and narrower, and the wear rate is decreased from 3.06 mg/cm2 to 1.02 mg/cm2.
