High temperature fretting wear behavior of WC-25Co coatings prepared by D-gun spraying on Ti-Al-Zr titanium alloy

► Mixed fretting regime was disappeared at different temperature in WC-25Co coatings prepared by D-gun spraying. ► Wear volume of the coatings obviously decreased with the increase of temperature in slip regime. ► WC-25Co coatings prepared by D-gun spraying exhibited an excellent fretting wear resistance.
