摘 要
本研究將延性鑄鐵經沃斯回火處理後形成沃斯回火延性鑄鐵(ADI)，為了維持其機械性
質及減少表面球墨孔洞，使用廣泛應用之電鍍銅表面改質方法，及以陰極電弧沉積法
(Cathodic arc deposition, CAD)於ADI表面披覆CrAlSiN陶瓷薄膜，再探討後熱處理對ADI披
覆電鍍銅與CrAlSiN膜層磨耗特性之影響。實驗結果顯示，以電鍍銅做為中介層，可以有
效提升CrAlSiN膜層之附著性，且經過後熱處理會有較明顯的Cr2N相產生而改善膜層的緻
密性，這也得使ADI表面硬度值提高，耐磨耗性質較好。

ABSTRACT
In this study, the ductile iron was heat-treated to form austempered ductile iron (ADI). In
order to maintain its mechanical properties and reduce surface spheroidal graphite pores, the two
surface modification methods of electroplating copper and cathodic arc deposition were used.
Cathodic arc deposition (CAD) method was used to coat CrAlSiN ceramic film on the surface of
ADI, and then the influence of the post heat treatment on the wear characteristics of ADI clad
both electroplating copper and CrAlSiN film was discussed. The experimental results showed
that the use of electroplating copper as the intermediary layer could effectively improve the
adhesion of the CrAlSiN film, and after post-heat treatment, the Cr2N phase was produced and
the compactness of the film also was improved. Such a result, the surface hardness of ADI could
be improved and have the better wear resistance.
Keywords: Austempered ductile iron, Electroplating copper, CrAlSiN ceramic film, Post heat
treatment, Wear resistance.
