Abstract

Copper-based alloys are commonly used in a wide range of applications. In order to reinforce their oxidation resistance they are usually coated with less prone materials. In this work the structure and the oxidation resistance of zinc coatings, deposited on copper and leaded brass substrates with pack cementation process is examined. It was found that coatings on copper substrate consist of two distinct layers corresponding to different Cu-Zn phases while the coatings on leaded brass substrate consist of a single Cu-Zn phase. Furthermore, the oxidation results showed that the coated samples have elevated oxidation resistance while bare substrates undergo severe damage..
