5. Sherardizing Sherardizing is the formation of a corrosionresistant, zinciron alloy coating, on the surface of steel or iron. The method involves the heating of the object in an airtight container that has zinc powder. A thermal diffusion process occurs and the zinc diffuses into the object's metal surface, forming the zinciron alloy. The external layer of the zinciron alloy formed is ...

1. When an active carburizer (charcoal mixed with barium or sodium carbonates) is used, the carburizing temperature of dense iron powder parts should not exceed 1223° K, as otherwise blister formation, swelling, and layering may take place on the surface of the parts. It is recommended that carburizing should be performed at ° K.
