Remote Controls, Inc. Offers a variety of Chemical Finishes to Iron and Steel Parts. 

BLACK OXIDE.  An oxide film formed by exposing iron parts to a hot solution of salts.  The finish is a tight knit, microscopic thin, film that efficiently traps and retains oil.  The entrapped oils provide enhanced corrosion resistance and provide an attractive Black finish. 

Specifications: AMS-2485, Mil-C-13924 plus various Customer Specs.

PHOSPHATE COATINGS.  RCI offers both Manganese and Zinc Phosphate coatings.  Formed by a chemical reaction between the process solution and the iron surface, these coatings are prescribed as a pretreatment for paints, for corrosion resistance, and as a "break-in" barrier on hardened and close fitting surfaces.

Specifications: Mil-P-16232, Mil-DTL-16232, DOD-P-16232, Mil-Std-171, plus various Customer Specs.

PASSIVATION of Stainless Steel.  Treatment of Stainless Steel surfaces to (a) remove traces of free iron and (b) produce a PASSIVE or IMMUNE barrier that inhibits and retards corrosion.

RCI has recently added the "CITRIC ACID PASSIVATION" process.  "Citric Passivation" provides Equal to Superior "PASSIVATION" while being vastly less dangerous and environmently harmful than the conventional Nitric Based processes.  Contact us for information on Capacity and Cost.
