Properties of FeCrBSiNi Wear-Resistance Coating by Supersonic Arc Spraying on Surface of Q235 Steel
摘 要
以FeCrBSiNi丝材为原料，利用自有专利技术的超音速电弧喷枪及喷涂装置在工业锅炉用Q235钢表面制备FeCrBSiNi涂层，研究了涂层的孔隙率、微观形貌、显微硬度、耐磨性能和结合强度。结果表明：超音速电弧喷涂制备的FeCrBSiNi涂层的孔隙率为0.71%，涂层与基体的结合界面相对平整，涂层没有明显的分层现象，涂层结构致密，孔洞较少；FeCrBSiNi涂层的平均显微硬度为720 HV0.3，远高于基体Q235钢的；涂层与基体以机械结合为主，结合强度可达到60 MPa；摩擦磨损试验后，基体的质量损失是涂层的28倍，涂层的耐磨性能远优于基体的。

Abstract
FeCrBSiNi coating was prepared on surface of Q235 steel used for industrial boiler by own patented supersonic arc spray gun and spraying device using FeCrBSiNi wire as raw material. The porosity, microstructure, micro-hardness, wear resistance and bonding strength of the coating were studied. The results show that the porosity of FeCrBSiNi coating prepared by supersonic arc spraying was 0.71%. The interface between the coating and substrate was relatively flat. The coating had no obvious delamination phenomenon. The structure of the coating was compact with few holes. The average micro-hardness of FeCrBSiNi coating was 720 HV0.3, much higher than that of substrate Q235 steel. The coating and the substrate was combined mechanically and the bonding strength reached 60 MPa. After the friction and wear test, the mass loss of the substrate was 28 times that of the coating, and the wear resistance of the coating was much better than that of the substrate.
