化学镀镍对铸铁热疲劳性能的影响

The Effect of Chemical Plating of Ni on the Thermal Fatigue Property of Cast Iron

采用实验室手段探索了表面化学镀镍对提高铸铁热疲劳抗力的作用。结果表明,化学镀镍可以提高铸铁的热疲劳抗力，但对灰铁不如对球铁有效。

The paper has made a study with laboratory method on the effect of chemical plating of Ni on the thermal fatigue property of cast iron.The results show that, chemical plating of Ni treatment can improved thermal fatigue property, but the effect improved of ductile cast iron is better than that of grey cast iron.
