Wear/Erosion Resistant High-Temperature Coatings

Numerous mechanical parts, including, rotary vanes, emission and intake blowers, rotor rings, boiler tubes, steam turbines, gas turbines, pulverized fuel supply lines, nozzles, and gun barrels, are susceptible to erosive wear. Due to the simultaneous effects of various factors such as particle size, velocity, hardness, and impact angle, this erosive wear phenomenon is extremely complex. To alleviate the problems caused by erosion, several technical solutions have been proposed. Amongst these coatings are one such solution. The application of high-temperature coatings was found to be an efficient technique to reduce erosive wear in extreme environments. In recent years, many ceramic and metal coatings have both advantages and drawbacks. Therefore, it is crucial to discuss how different high-temperature coatings might enhance the erosive wear resistance. The technology development, influencing variables, properties, and failures of high-temperature erosion-resistant coatings are therefore highlighted in the current chapter. This could open up new opportunities for research into cutting-edge high-temperature erosive wear resistance coatings.
