Abstract
This study aimed to prepare Cu-based coatings with excellent corrosion resistance by cold spraying. Cu, Zn, and Al particles with different mass ratios were mechanically blended as the feedstock materials. The microstructure, element content, mechanical properties, and corrosion resistance of the coatings were investigated. Results showed that all the prepared coatings presented a dense microstructure. In addition, the thickness of the coatings exceeded 290 μm, and the existence of the “hammer effect” made the thickness and hardness of the coatings present an obvious negative correlation. Electrochemical test results indicated that changes in the element content could significantly affect the corrosion behavior of coatings. During the immersion period, the coatings containing Al exhibited better corrosion resistance.
