[Problem] In corrosive and abrasive environments, it is considered that low-grade materials such as carbon steel can be coated with corrosion-resistant and wear-resistant thermal sprayed coatings to provide functionality as an alternative to conventional high-grade materials. The problem is that although the thermal spray coating itself is corrosion resistant, the fine pores unique to the thermal spray coating allow corrosive solutions to reach the material.
As a result, corrosion of the material and eventually peeling of the sprayed coating will occur. Therefore, the development of a structure and manufacturing method for a coating that can protect materials with poor corrosion resistance even if a corrosive solution permeates the thermal spray coating has been awaited.
