Tribology Properties of Fe-based Amorphous and Nanocrystalline Coatings Prepared by Automatic Arc Spraying Process
Fe基非晶纳米晶电弧喷涂层的摩擦学性能

Automatic high velocity arc spraying process was used to deposit the FeCrBSiMnNbW amorphous and nanocrystalline coating on an AZ91 magnesium alloy substrate.The tribological properties of the coating under dry sliding were investigated on a UMT-2 micro tribo-tester.The microstructure of the coating was characterized by using scanning electron microscopy(SEM) equipped with energy dispersive X-ray analysis(EDAX) and X-ray diffraction(XRD).Mechanical properties were measured on Vickers hardness tester and nano...
