Wind power is a clean energy source, has been widely used in various countries in recently , Corrosion protection is a major concern for every generator user. Excellent protection ensures a longer service life of the wind turbine, eliminating the need for frequent renewal of coatings and continuing to invest more money and shortening the payback period.

Offshore photovoltaic support is an important support structure for offshore power generation systems, and its anti-corrosion performance and service life are very important. Common offshore photovoltaic support materials are carbon steel, stainless steel and aluminum alloy. The Marine environment is extremely corrosive to photovoltaic supports, including factors such as seawater, salt spray, humid air and ultraviolet light. This corrosion environment is 55 times faster than that of the dry northwest of China.
