Anti-corrosion treatment of magnets for wind turbine generators

Why is corrosion important for offshore wind generators?

Corrosion is a critical phenomenon to be considered in the design, construction, commissioning, and operation lifetime of offshore structures such as offshore wind generators.

Why is corrosion protection important for turbines?

The high salinity, humidity, and wave action around the splash zone create different problems, and corrosion protection must be much more robust. New technologies are required to provide protection for larger turbines in deeper water and harsher conditions, with new types of foundations.

Are monopile-based wind turbines corrosion prone?

However, differences in construction details between monopile-based wind turbines and multiple legged platforms as well as the necessary choice of non-proven protection technology have since given rise to different corrosion related issues inside and outside the foundations.

How to improve coercivity and corrosion resistance of Nd-Ce-Fe-B sintered magnets?

Improvement of the coercivity and corrosion resistance of Nd–Fe–B sintered magnets by intergranular addition of Tb 62.5 Co 37.5 Grain boundary engineering towards high-figure-of-merit Nd-Ce-Fe-B sintered magnets: synergetic effects of (Nd, Pr)Hx and Cu co-dopants

Can NDT methods be used for corrosion monitoring in offshore wind?

TABLE 2. Comparative study of feasible NDT methods for corrosion monitoring in offshore wind. Taking all the requirements and the OWT use case into account, the ultrasound (US) technique seems a very promising candidate for the design of a corrosion monitoring solution as is shown in Table 2:

Why do offshore turbines need anti-corrosion coatings?

The harsh environment offshore requires highly effective anti-corrosion coatings and the difference in exposure compared with onshore turbines is vast.
