Progress of Multifunctional Organic Bonded Coatings with Lubrication,Wear and Corrosion
With the rapid development of modern equipment technology,the service conditions of high-end machinery and equipment have become more complex and demanding,and the coupling damage of wear and corrosion has accelerated the damage and failure of moving parts of high-end machinery and equipment,resulting in a significant reduction in the service life of equipment and serious safety problems.The integrated organic bond coating overcomes the single functional limitations of the lubricating wear-resistant coating and anti-corrosion coating,and provides an effective solution to the wear and corrosion problems of moving parts.This paper first discussed the severe challenge of key moving parts facing complex service conditions,the coupling damage mechanism of material wear and corrosion;then,the research progress of organic bonded coatings with integrated lubrication,wear resistance and corrosion resistance was introduced from three aspects:binder,filler and lubricant.The structure-activity relationship between the composition and mechanical properties,tribological properties and corrosion resistance of coatings was analyzed,and the limitations of different coatings were summarized.Then,the application status of integrated coating with lubrication,wear and corrosion resistance was summarized in detail.Finally,the development direction of integrated coatings with lubrication,wear and corrosion resistance was prospected.
