Study on Making Ceramic Composite Steel Plate by SHS Process
Large cross-section composite rectangular steel tubes with ceramics inner liner, which can be used directly, and also cut into the ceramics clad plate, were made by a new effective way. The material type, shape and size parameters of cores were determined and thickness and hardness of the ceramic coating were measured. The bond stress between steel substrate and alumina ceramics were analyzed and the bond modes also were checked. The dimension parameters of hemming plate used in the experiment were determined and the bond strength between the coating and tube substrate in normal and tangential direction was examined. The results show that the ceramics coating surface is glossy, which thickness is among 1.5-3.5 mm, the hardness of alumina ceramics inner liner is above HV1100. Metallurgical bonding between steel substrate and ceramics coating could not come into being and the mechanical bonding with lower bonding force is the mainly joint mode.
