The Effect of Boron-Sulphurizing Rare Earth on Microstructure and Properties of Boronized Layer

Abstract:

In this paper studies the effect of the temperature of boronized layer, holding time and formula of accelerant on the microstructure and properties boronized layer. The result shows that the thickness of boronized layer increases with the increasing of temperature of boronized layer and the holding time expansion. In the experiment, the research contrasts the effect of five groups of boron-sulphurizing rare earths co-cementation and finds that the best effect is to add 1.5% sulfide and 5% rare earth in reagent. The metallographic analysis and hardness testing show that the properties of boronized layer have improved evidently.
