Process fluids
Blackfast is the room temperature black oxide process that turns steel and cast iron black at around 20 °C. For the complete cycle Phibo supplies the four process fluids and the tanks your parts go through. The blacking paste for manual work is available here as well.
Four fluids
Every step of the cycle has its own fluid: degreaser, conditioner, blacking fluid and corrosion protector.
Removes oil, grease and soiling from the surface. Without that step there is no even black.
Lowers the pH value of the surface, after degreasing and rinsing with water.
This is where the part takes on its deep black colour, at around 20 °C.
A water-displacing oil that dries and protects the blackened surface, suitable for indoor applications.
In practice
The blacking cycle
Parts go through the baths in a fixed order, according to parameters set in advance.
The surface is cleaned and degreased, free of mill scale, rust and other residues. That step is essential for a high quality black finish.
After degreasing and rinsing, the parts go into the conditioner to lower the pH value.
In the blacking fluid, one minute is enough for a uniform black surface. Above 22 °C or with special materials, thirty seconds can be enough.
Finally the parts go into a water displacing oil. It drives out the water and leaves a protective layer after drying.
