等离子喷涂高温自润滑涂层的发展概况

Development Survery of High Temperature Self-Lubrication Coatings Prepared by Plasma Spraying

为了满足高新技术发展的需要，研制从常温到８００℃乃至１０００℃都具有良好摩擦学性能的固体润滑材料，是高温固体润滑领域的一个重要研究课题，而开展等离子喷涂高温自润滑涂层的研究，则是达到这个目的的有效途径之一。因此，在已有研究工作的基础上，通过文献调查对国内外等离子喷涂高温自润滑涂层的发展概况作了综合介绍与评述，并就其基体（连续相）、润滑相和耐磨相等进行了比较全面的分析与讨论。结论认为，要加速解决工程实际中的高温润滑问题，就应当充分利用已有的研究成果，向不同材料（如自润滑耐磨合金、非金属基材料及陶瓷）和应用超音速等离子喷涂技术的方向发展。

To meet the needs of development of high-new technology,developing the solidlubrication material which has the good tribological properties at high temperature(800℃ to1000℃)is one of the major subject of high temperature sofid lubrication area. Cattying out thestudy on the high temperature self-lubrication coating treated by plasma spraying is one of theeffective ways to achieve this goal,therefore,on the basis of existing work,the developmentsurvey of high temperature self- lubrication coating prepared by plasma spraying at home and abroadwas reviewed by literature in vestigation ,and the matrix(continuous phase), lubrication phase andantiwear phase was entirely analyzed and discussed.To conclude that to solve the high temperaturelubrication problem exiting in the engineering practice, achievements in scientific research should beused, the different materials(self-lubrication antiwear alloys,non-metal base materials andceramics)and the ultrasonic plasma spraying technique also should be developed.
