SETT ATT VARMMETALLISERA METALLFOREMAL

摘要

In order to improve the quality of an alloy e.g. Zn/Al coating formed by immersion in a liquid bath of the alloy, the metal object to be coated is first immersed in a liquid bath of zinc. There is thus no need for special pretreatment other than that conventionally provided before galvanizing. The Zn/Al bath may be maintained at approx. 600 DEG C and may further include Mg and/or Si. Forced drying may be provided after each bath.
