Phosphating

Doogood can offer both Zinc and Manganese Phosphating coatings. Phosphating is a process commonly used on steel components for corrosion protection, lubricity or as a pre-treatment for further coating or painting. A typical Phosphating process will include a series of cleaning, pickling and rinsing processes, prior to the parts being immersed in a Phosphate bath and subsequently rinsed and dried or treated with oil.

Phosphating will only provide short term corrosion protection when treated with a oil, grease or other sealer. On it’s own it will provide very little corrosion resistance due to the porous nature of the coating. This is commonly known as Phosphate & Oil.

Being a porous, crystallized finish phosphate is a superb pre-treatment for most coatings with it’s excellent adhesion properties due to the porosity allowing for additional materials to seep into the coating, therefore becoming mechanically interlocked after curing.

We apply our Phosphate coating processes as per AS1627.6-1994 Preparation and Pre-Treatment of surfaces – Chemical conversion treatment of metals. We take regular titrations on all baths involved in our Phosphate process to ensure we remain within specifications at all times.
