This process is ideal for a decorative finish on ferris metals where no
dimensional change is required and no hydrogen enbritlement will occur. Fine
springs & delicate instruments will occur no damage. All types of machinery
such as printing press parts, conveyors, tools, aircraft maintenance
tooling, rifles, guns, lathe parts, manufactured items that need a
professional finish with rust inhibiting properties.

Parkerizing
A zinc phosphate coating giving a good corrosion resistance as well a
good base for painting. There is a build up of coating but it is crushable
to an extent. The coat must be sealed by light oil or a lacquer as it is
slightly porous in nature.

Manganese Phosphate
If a black satin finish with very little dimensional
change is required this would suit. Ferrophos is also heat resistant with a
good abrasive resistance. Being inexpensive it becomes ideal for a cosmetic
finish on all those little jobs needing to look professional. One advantage
is the article can be coated when assembled and will not lock up as with
powdercoat. |
