中文摘要：利用重力分离SHS技术在带卷边钢板表面直接制备了陶瓷复合涂层。测量了涂层厚度和硬度，分析了钢基体与氧化铝陶瓷结合力产生的原因， 确定了二者的结合方式及卷边钢板的工艺尺寸参数，检测了涂层与基体法向和切向结合强度。结果表明，陶瓷复合钢板的涂层表面光滑，其硬度在1100 HV以上；钢基体与陶瓷涂层主要是机械嵌合。
英文摘要：Using gravitational separation SHS process, ceramic coating was prepared in hemming steel plate. The thickness and hardness of the ceramic coating were measured. The causes for bonding stress between steel substrate and alumina ceramics were analyzed and the modes of the bond were found. The technology dimension parameters and bonding strength between the coating and plate substrate in normal and tangential direction were confirmed. The results indicate that the surface of the ceramic coating is glossy. The hardness of the ceramic coating is above 1100 HV. The mode of the bonding between steel substrate and ceramics coating is mainly mechanical bonding.
