HOT BLACK OXIDE

 

We are the only finishing company that offers hot black oxiding for oil field components.  This black hot oxide finish can be applied to carbon and stainless components.
Our in-house hot black oxide coating is widely used for the oil field, machine tool, automotive, appliance and general forming parts.


 

 

What are the advantages and benefits of black oxide coating?


Dimensional Stability – Black oxide adds no more then 5 to 10 millionths of an inch to the dimension of a part (it also penetrates to an approximate depth of 5 to 10 millionths).  For all intents and purposes, the as-formed dimensions do not change (as they do when plated or painted).
 
Anti-galling – Where break-in of mating parts is necessary, the anti-galling surface lets the outer lubricating layer be sacrificed during the initial contact and abrasion while work-hardened surfaces are formed.  The black oxide itself has a hardness of 5.5 on the Moh’s scale.
 
Improved Lubricity – Oil post-treatment not only protects against corrosion, but will add lubricity in mating parts.

Decorative Finish – The resulting lustrous black finish adds visual appeal and a “quality” image.
 
Corrosion Protection – Black oxide coating can give stainless and carbon steel components corrosion resistance.
 
Reduced Light Glare – Moving machine parts, hand tools and surgical instruments coated with black oxide reflect less light and reduce eye fatigue when used under bright lights.
 
Cost Competitive - It is very difficult to achieve the same protection, appearance, and performance qualities from other finishing processes as black oxide.
