Mechanical and electrochemical properties of Zr and Zr–Er alloyed layers deposited on titanium alloy (TC11)

In this paper, Zr and Zr–Er alloyed layers were deposited onto the TC11 alloy by using double-glow plasma surface alloying technique. Microstructure analysis showed that Zr and Zr–Er alloyed layers were both well bonded to the substrate without defects of porosity and cracks. Nanoindentation test reflected that Zr and Zr–Er alloyed layers not only possessed high hardness but also had good elastic property. The electrochemical behavior of Zr and...
