Wear And Corrosion Resistance

Compared with ordinary coatings, nano-composite coating usually has a higher hardness and better wear and corrosion resistance. As coating materials, the nano-CeO2/Zn composites were prepared by nano-CeO2 and Zn powder. The microstructure was investigated by XRD and FESEM. The corrosion resistance and hardness of nano-CeO2/Zn composites with different amount of nano-CeO2 were comparatively studied. The results show that the metal corrosion resistance, hardness and density of the composites may be improved significantly by addition of nano-CeO2, and the optimal amount of nano-CeO2 is 1%.

Wear And Corrosion Resistance

Nitrotec is characterized as a low-distortion treatment for ferrous materials where surface enrichment, predominantly by nitrogen, forms a hard surface layer of epsilon iron nitride, beneath which there is a nitrogen diffusion zone. The surface layer imparts wear and corrosion resistance and the diffusion zone increases the yield and fatigue strength, particularly in thin section sizes. Process developments have significantly enhanced the corrosion resistance and aesthetic appearance of treated components to make Nitrotec competitive with electroplated finishes. Major commercialization took place during the 1980s with a wide range of successful applications from windscreen wiper systems to bumper armatures, using combinations of the unique properties obtainable from the process to provide cost and weight savings.

Wear And Corrosion Resistance

Thermal spraying coating techniques have emerged as very effective surface protection technology to apply protective coatings for corrosion and wear resistance applications. These coatings have gained more importance in recent past. Advances in powder and wire production have resulted in development of various types of surface coatings with excellent wear and corrosion resistance properties. Because of excellent mechanical, thermal and electrical properties of Carbon Nanotubes, CNTs reinforced composite coatings are being developed for various applications, e.g. automotive, aerospace and sports equipment industry. It is observed that if properly deposited, these CNTs ceramic composite coatings can provide improved properties like wear and corrosion resistance. It has been found that CNTs composite coatings can be successfully deposited by thermal spraying techniques, and these coatings provide better performance than conventional coatings. This paper reviews the performance of such coatings developed by various researchers.
