The brittleness of intermetallic compounds severely hampers their appliance in industry as high temperature structural materials. In order to make use of their good qualities and avoid the influence of their disadvantages, this paper put forward another method on the application of intermetallic compounds--using as coatings on the surface of structural materials. Lots of experiments have been done on Fe-Cr-Al intermetallic compounds and excellent coatings were acquired by high temperature in-situ reaction process. The coating is compact and bonded well with substrate. And the result of experiment shows that it has wonderful corrosion resistance to molten zinc. |
