Black Oxide is an inexpensive conversion coating that does not chip, flake, or create dimensional changes and can be welded. Adding an oil or topcoat adds corrosion resistance to the oxide coating.

Chemical conversion coatings are applied to aluminum and zinc substrates to slow corrosion and are great for paint adhesion and low electrical resistance. Our RoHS-compliant conversion coatings are used in many industry applications.

Electroless Nickel Plating uses chemical processes to plate nickel onto steel, aluminum, brass, stainless steel, and zinc die-cast for corrosion and wear protection, solderability, and lubricity. Its unique properties allow us to engineer this coating to function in many applications.

Electroless Nickel Boron is a popular coating chemically applied to uniformly coat complex shapes. It increases hardness, heat, and wear resistance while providing lubricity to reduce abrasion.

Electropolishing is an electrochemical process that removes material from a stainless steel part. It is used to chemically polish and brighten a part, with the added benefit of removing free iron from the surface.

Avtec Finishing Systems offers nitric acid passivation, sodium dichromate, and citric acid passivation to remove free iron from the surface of stainless steel and prevent corrosion.

Type II Anodizing, or Sulfuric Acid Anodizing, uses electrolytic oxidation to create an aluminum oxide surface on an aluminum part for increased wear and corrosion resistance, heat dissipation, and aesthetics.

Type III Anodizing, also known as Hardcoat Anodize or Hard Anodizing, creates a thicker and more durable layer than Type II Anodizing. Hardcoat is corrosion resistant and non-conductive. With wear properties similar to a part with a Rockwell Hardness over 60, it is a very durable coating option for aluminum.

Both Avtec Finishing and Nico Products offer numerous value-added services, including dry film lubricants, blasting, tumbling, masking, baking, and more.

Solvent vapor degreasing is a popular parts-cleaning process for removing contaminants on materials in the medical, electronics, aerospace, and communications industries. Removing contaminants, oil, and debris from parts provides clean surface conditions for successfully plating your parts.
