Just received a shipment of parts. I'm familiar with the brownish-black
"black oxide" method of coloring steel, but these came in glossy and coated
almost like a black anodized aluminum part... But not as durable as either
anodizing or oxide...
It's not paint... It's more durable than that or even a sharpie marker...
Any clue what the difference is between methods of "blackening" the steel?

Please log in for more thread options Our parts always came glossy, almost "waxy"... then we switched vendors
and got the dirty, brown, crappy black oxide that comes off on your hands
and clothes. The difference appears to be the "sealer"... or lack of sealer
on the brown parts.
Caswell sells their regular penetrating sealant and a new acrylic
"non-oily" sealant.

How about Iron Phosphate. It is a harder black conversion coating,
which when oiled is VERY shiny and quite durable.

Please log in for more thread options If it feels/looks like anodizing, it might be "e-kote"
http://www.metokote.com/coatingTechnologies/electrocoating.asp
The process is about half way between a dip painting and a plating
process. Prduces a very good corrosion inhibitor but it is not as
durable as paint and does not do well when exposed to UV. It makes a
great undercoat/primer for powder coating. Snowmobile (Arctic Cat) and
commercial lawn mower (Toro) use E-kote then powder.

Sounds like Electro Coating. Basically a THIN paint process that applies
the coating using electrostatic spray or dip. Depending on the material
it can be a good finish or a crappy one.
