Abstract
To improve the tribological and anticorrosive performances of the copper alloy engine bearings, three types of EP/PAI/PI-PTFE coatings filled with ZnO and Ce2O3 were prepared on the surfaces of CuPb22Sn2.5 by liquid spraying. Their performances and mechanisms were studied under different lubrication conditions and different temperatures. The results show that the excessive ZnO leads to agglomeration phenomenon and increases pores of the coating. As the content of Ce2O3 increase, the pores and defects of the coatings are reduced, and the hydrophobicity of the coating is improved. The coating with 2 wt % ZnO + 3 wt % Ce2O3 has the best wear resistance and corrosion resistance at all conditions. Hardness has the more dominant influence on wear rather than lubricant media.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
