【Abstract】 The effect of compound CeCl₂ on the nitrocarburizing kinetics process、microstructures and properties of steel 45 was studied. Comparing with the normal nitrocarburizing processes, the nitrocarburizing processes with CeCl₂ addition improve microstructures and properties remarkably. CeCl₂ may be regarded as not only a catalyst in diffusing medium for thermochemical processes but also a micro-alloying elemert.更多还原
