| Abstract: | This paper deals with the kinetics and catalysis mechanism of rare-earth elements on nitrocarburizing for ductile iron by adding various amount of rare-earth elements into conventional nitrocarburizing mediums.When Rare-earth catalyzed nitrocarburizing for ductile iron crankshaft of diesel engine,the nitrocarburizing rate can be increased 55% and the productivity can be increased 33% compared with conventional nitrocarburization and the properties (microhardness, toughness, wear resistance, fatigue resistance) of layer can be increased remarkably,the quality of products can be stabilized. It possesses remarkable economical and social benefits. |
