To prevent wear and corrosion of mechanical parts, we all should analyze the cause of abrasion first, as there are different measures to prevent and resolve for different types mechanical wear and corrosion. For example, heat treatment or surface heat treatment can significantly improve the he anti adhesive wear ability between friction pieces, Oxidizing and phosphating, sulfide, chromium plating, aluminizing process can reduce the damage caused by corrosion and oxidation, and easy to wear parts made from hardfacing wear resistant alloy materials can significantly improve the abrasion resistance ability of parts.

The most easy to wear equipment in thermal power plant is heating surface of boiler and auxiliary boiler (fan, coal mill and ash feeding system), and hydraulic turbines is the most vulnerable  equipment in hydro-power station. To prevent mechanical damage and wear, we should know how to choose suitable wear resistant materials for these. The wear damage accident will be reduced if we can select reasonable wear resistant steel with high abrasion resistance and wear-resistant alloy. Besides,we can also enhance the surface wear resistance by welding wear resistant alloy materials on the steel plate surface.

Welding and spraying are effective ways to improve the wear resistance of parts as wear and abrasion often occurred on the surface of parts. This can also save a lot of valuable wear-resistant alloy and reduce the manufacturing cost, therefor they are widely used in the damaged parts.
