| Abstract: | AlCrN coating was deposited on the surface of Cast-iron piston ring by multi-arc ion plating.Al target arc current was investigated to study the effect on microstructures and mechanical properties of the AlCrN coating as other parameters remain.Scanning Electron Microscope,X-Ray Diffraction,Microhardness Tester and MM-200 friction testing machine were used to test the microhardness,surface microstructure and friction factor of the coating.The result shows that the Al target arc current has a great influence on the microstructure and mechanical property of the coating.As the Al target arc current raises,amount of Al in the coating increases,while the microhardness and friction factor decline.And with the amount of Al in the coating raises,amount of Al particles and the density increase. |
