Method for rapidly preparing manganese-cobalt spinel coating through microwave mixed heating
The invention discloses a method for rapidly preparing a manganese-cobalt spinel coating through microwave mixed heating, relates to the technical field of microwave processing and metal surface modification, and aims at solving the problems that components are uncontrollable, the preparation process is tedious, base metal is seriously oxidized and the like when the manganese-cobalt spinel coating is prepared through a traditional technology. The method for preparing the manganese-cobalt spinel coating comprises the following steps: 1, weighing Co powder, MnO2 powder and sintering aid powder as raw materials; 2, placing the raw materials in a ball-milling tank for wet ball-milling treatment; 3, carrying out surface treatment on the ferritic stainless steel; 4, evenly smearing the mixed powder on the surface of the ferritic stainless steel, and performing compression molding; and 5, imbedding the stainless steel attached with the prepressing coating in the high-microwave-absorptivity powder in the microwave sintering furnace, and performing sintering and heat preservation in the air atmosphere. The manganese-cobalt spinel protective layer is prepared by adopting a microwave mixed heating method, the heating rate is high, the heating efficiency is high, the sintering temperature is greatly reduced, the sintering time is shortened, overall uniform heating is realized, and the internal stress of the coating is small.
一种微波混合加热快速制备锰钴尖晶石涂层的方法,本发明涉及微波加工和金属表面改性技术领域,它要解决传统技术制备锰钴尖晶石涂层时成分不可控、制备过程繁琐、母材氧化严重等问题。制备锰钴尖晶石涂层的方法:一、称取Co粉末、MnO2粉末及烧结助剂粉末作为原料;二、原料置于球磨罐中湿法球磨处理;三、对铁素体不锈钢进行表面处理;四、将混合粉体均匀涂抹在铁素体不锈钢表面,模压成型;五、将附有预压涂层的不锈钢埋入微波烧结炉内的高微波吸收率粉末中,于空气气氛下烧结保温。本发明采用微波混合加热法制备锰钴尖晶石保护层,升温速率快,加热效率高,极大降低烧结温度,缩短烧结时间,实现整体均匀升温,涂层内应力小。
