Manganese phosphate coating on steel: issues and answers

It is a conversion coating process and involves the dissolution of the base metal which subsequently forms part of the coating. In manganese phosphate coating the species that deposits on steel is manganese iron phosphate and hence requires a large amount of metal dissolution so that the formation of manganese iron phosphate is possible.

manganese phosphate coating -

May 16, 2008· Manganese phosphate was a complete failure (completely rusty), it was actually worse than black oxide and the same as uncoated steel. Parkerising showed no rust at all. Black oxide was about half and half. I believe both manganese phosphate and parkerizing take in some oil, so it helps to oil these finishes. Also, a wax spray can help black oxide.

Treating Manganese in Well Water – Pure Water Products, LLC

TDS: Softeners remove manganese best if the total dissolved solids (TDS) of the water is low. When TDS is high, other minerals in the water compete with the manganese for space on the resin and can even displace manganese which has attached to the resin. Water with . 500 ppm TDS works best for manganese removal by a water softener.
