摘要
在航空、航天、冶金、电力、石化、矿采等领域,零件高温摩擦磨损特性是影响装备寿命的重要因素,在关重零部件表面设计制备宽温域耐磨自润滑涂层是装备零件强化改性和再制造修复的重要手段。首先阐述了宽温域耐磨自润滑涂层设计中过渡层、基础相、增强相的材料选择依据;其次针对单一固体润滑剂适用温度范围窄的问题,梳理了从低温润滑剂发生氧化反应原位生成高温润滑剂,低温润滑剂与高温润滑剂长时协同作用,添加抑制剂减缓润滑相的损耗退化等三种宽温域耐磨自润滑涂层材料设计方法;而后总结了宽温域耐磨自润滑涂层的制备工艺,分析了不同喷涂工艺的技术特点和涂层制备实例,介绍了宽温域耐磨自润滑涂层在军事装备和工业设备上的典型应用;最后在此基础上对宽温域耐磨自润滑涂层的未来发展方向进行了展望。
In aviation,aerospace,metallurgy,electric power,petrochemical,mining and other fields,the high-temperature friction and wear characteristics of parts are important factors affecting the service life of equipment.The design and preparation of wide temperature range wear-resistant self-lubricating coatings on the surface of key parts are important means for strengthening modification and remanufacturing repairing of equipment parts.Firstly,the material selection basis of transition layer,basic phase and reinforcing phase in the design of wear-resistant self-lubricating coating with wide temperature range is described;Secondly,in view of the narrow applicable temperature range of a single solid lubricant,three design methods of wear-resistant self-lubricating coating materials with wide temperature range are sorted out,including in-situ formation of high-temperature lubricant from oxidation reaction of low-temperature lubricant,synergistic effect of low-temperature lubricant and high-temperature lubricant,and adding inhibitors to reduce the loss and degradation of lubricating phase;Then it is summarized that the preparation process of wide temperature range wear-resistant self-lubricating coatings,the technical characteristics of different spraying processes and the instance of coating preparation,and introduced that the typical applications of wide temperature range wear-resistant self-lubricating coating in military equipment and industrial equipment;Finally,it is prospected the development of wear-resistant and self-lubricating coatings with wide temperature range in the future.
