【Abstract】 Influence of rare earth on low temperature salt-bath chromizing on 45 steel was studied. The experiment result shows that the rare earth can increase the depth of the chromizing layer and its hardness.The author thinks that the rare earth give an impetus to low temperature salt-bath chromizing.更多还原
