In some cases, the use of pulse current still can reduce the lumber, improve the hydrogen cathodic current efficiency, thus reduce pinhole, striped and hydrogen brittleness, etc.
The zinc aluminum coating (also called "Dacromet") is a recently developed anticorrosive technology which has the advantages of high anticorrosion, low pollution and no hydrogen brittleness.
Zinc alloy coatings can be obtained from suitable range of bath, and it has attracted a great attention due to their unique high corrosion resistance, low hydrogen brittleness and chemical stability.
