- Chromate treatment and zinc phosphate treatment are commonly used as surface treatments for zinc-based metal materials used in automobiles, home appliances, building materials, etc., but the toxicity of chromium poses a problem. ing. Chromate treatment has the following problems: chromate fume is volatilized in the treatment process, wastewater treatment equipment is very expensive, and chromic acid is eluted from the chemical conversion coating. Hexavalent chromium compounds are extremely harmful because many public institutions have designated them as carcinogens for the human body, including the International Agency for Research on Cancer Review (IARC).
