| Abstract: | The friction and wear properties of HEP Jet coating of Cu-14Al-X under dry sliding are mainly discussed in thispaper. The Cu-14Al-X powder was coated onto 45 steel by HEP Jet technique, and friction and wear test was conducted onMMW-1 friction and wear testing machine. The hardness of coating and worn surface morphology were respectively tested bymicro-hardness tester and scanning electron microscope （SEM）. The results show that the microhardness of HEP Jet coatingis up to 360 HV, and the wear mechanism of HEP Jet coating of Cu-14Al-X under dry sliding is adhesive wear under lowerload （100N-200N）, and adhesive wear with abrasive wear under medium load （300N-420N）, and adhesive wear again un-der high load 540N. The coating possesses great self-lubrication and wear-resistance, and belongs to mild wear, especiallyunder high load. |
