Fretting Corrosion Behavior of Zn-Al-Mg-RE Coating under Dry Friction and NaCI Solution
The fretting behavior of Zn-AI-Mg-RE coating prepared by high velocity arc spraying was studied for the first time in this paper. All specimens were fretted in air and 3.5％NaCl solution independently. The worn surfaces of the coating were investigated by scanning electron microscopy and X-ray energy dispersive spectroscopy. Fretting tests have shown that friction coefficient in 3.5％NaCl solution was similar to dry condition for Zn-AI-Mg-RE coating. Study of worn surfaces revealed the main mechanism in dry friction was the oxidative wear; while in 3.5％NaCl solution, the main mechanisms were delamination process and abrasive wear.
