1. Chromate conversion is a type of conversion coating used to passivate a number of alloys

2. Antimony Antimony -based passivation was introduced by Phillips Petroleum in 1976 to passivate nickel compounds in the FCC feed

3. Trivalent Passivate/Chromate FAQ 1) What are passivates/Chromates? Passivates/Chromates are used to coat metal parts in order to provide a longer life for the part

4. By analogy to observed natural processes, an electrochemical method is described that is intended to re-alkalize the carbonatized top layer, and re-passivate the steel reinforcements that are no longer protected from corrosion by an alkaline environment by means of drying/humidification cycles.
