Microstructure and Wear Properties of Iron-based Alloy Coating by Laser Cladding

摘要：

　　The iron-based alloy coating was obtainment by laser cladding on grey cast iron (HT250).The microstructure and morphology of laser cladding were observed by scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS).The mierohardness of laser cladding coating was tested.The wear properties of laser cladding coating and grey east iron at room temperature without lubrication were evaluated by sliding wear tests.It was show that the laser cladding coating on grey cast iron has a homogeneous and dense microstructure.It was observed that the laser cladding coating presents a great hardness (average of 747 HV) and excellent wear resistance.
