Advantages to our Vaporblack Process
- Blacking time dramatically reduced.
- Non-hazardous blacking, environmentally friendly
- Self-contained, space-saving design.
- Operation at room temperature (18°C to 24°C).
- No pre-cleaning required.
- No dimensional change to components.
- Inherent corrosion protection.
Traditional methods of blacking iron and steel
machined parts involve the use of aggressive caustic-based
solutions, often in open tanks, operating at temperatures
up to 140°C.
The Vaporblack process enables parts to be processed
for blacking at room temperature (18°C to 24°C)
employing a special chemical that is far more environmentally
friendly than conventional solutions and non-hazardous
Typical process time is less than five minutes, compared
with the 45 minutes needed for traditional blacking.
The process comprises wet blast pre-cleaning in the
first chamber to remove surface contamination, such
as heat treatment oxides and scale, followed by blacking
with Blackfast 181 blacking solution in the second chamber,
a water wash and then the application of a surface sealant
(Blackfast 833) using dip tanks mounted to the right
of the second chamber.
The operation is carried out manually under preset
process control parameters.
Immersion in Blackfast 181 removes minute particles
of iron and steel from the component surface and replaces
these with an iron copper complex, which is then oxidised
(black). The surface complex produced by the process
is similar to a phosphate finish but, importantly, there
are no dimensional changes. The Blackfasted substrate
will absorb oil / wax sealants into the component surface
to give the treated parts corrosion protection.
