Abstract

The invention relates to an anticorrosive application of a thermal spraying technology on electricity-generating members of a wind-driven generator. A zinc-aluminum alloy material is sprayed on the electricity-generating members of a wind-driven generator through a thermal spraying technology so as to form an anticorrosive layer. Compared to the prior art, an anticorrosive layer is formed by spraying a zinc-aluminum alloy material on the electricity-generating members of a wind-driven generator through a thermal spraying technology, and the anticorrosive layer protects the iron steel substrate on the basis of the oxygen gas insulation theory and the sacrificial anode protection theory. The thermal spraying technology adopts a zinc-aluminum alloy material as the spraying material, and the zinc-aluminum alloy material has the advantages of low cost, simple preparation technology, and good anticorrosive performance. A film is formed on the electricity-generating members of a wind-driven generator through a thermal spraying method so as to effectively alleviate the corrosion.

Description

technical field [0001] The invention relates to the application of a thermal spraying process, in particular to the anticorrosion application of a thermal spraying process on the power generating components of the wind power generator. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Our country is rich in energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kW, while the total installed power capacity of the country at the end of 2003 was about 567 million kW. It can be seen that wind power has broad prospects and market benefits in my country. [0003] However, the various parts of wind turbines are basically cast iron or steel parts. These parts will rust after long-term use, and the height of the wind turbine body is very high after installation, so how can these parts be used for decades? No rust in use is a necessary condit...
