Surface defects, characteristic of high-zinc cast brass, which form when zinc vapor condenses on the surface of the metal, where it is oxidized and then absorbed by the solidifying metal. Zincrometal - Zincrometal. Steel product with a coating consisting of an oxide sub-layer containing zinc particles and a zinc-rich organic top layer. It is weldable, formable, paintable and compatible with commonly used adhesives. Zincrometal is used to protect the exterior of cars from corrosion. Zone melting - zone melting. Highly localized melting is usually induction heating of a small volume of a metal bar. Moving the coil of the inductor along the rod, the molten zone passes from one end to the other. In binary compositions, where there is a large difference in composition on the liquidus and solidus lines, high purity can be achieved by concentrating one of the elements in the liquid moving along the rod.
