Sherardisingとは 意味・読み方・使い方

Sherardising or sherardizing is a method of galvanising also called vapour galvanising. It is named for its discoverer Sherard Cowper-Coles (1900). Zinc evaporates and diffuses into the metal target object forming Zn-Fe-phases by heating the object in an airtight container with zinc powder. The temperature that the container reaches normally does not exceed the melting point of zinc. Another method of sherardisation is to expose the intended objects to vapour from molten zinc using a reducing gas to prevent oxidation.
