钢铁发黑技术的现状及展望

Current status and prospect of the blackening of iron and steel

钢铁发黑主要包括高温碱性发黑、常温发黑、常温无毒发黑、黑色磷化、化学镀和电镀黑色镀层。概述了发黑技术的机理及现状 。

The blackening of iron and steel includes alkaline blackening at high temperature, blackening at room temperature, non-toxic blackening at room temperature, black phosphating, blackening on electroless and electro-deposits, and black nickel-zinc or nickel-tin alloy electrodeposits. Mechanism, current status of the blackening of iron and steel were described, direction of the study in future was suggested.
