Plating For Corrosion Resistance On Steel

What Are The Best Plating Processes For Corrosion Resistance For Steel?

Corrosion will jeopardize the integrity of components of aircrafts, vehicles, and many other all types of equipment. Paramount Metal Finishing provides metal plating solutions that improve the corrosion resistance of metal parts for the aerospace, military, medical as well as industrial and energy industries. The following brief guide offers the best plating solutions Paramount Metal Finishing offers for corrosion resistance to help you decide which type of plating may best fit your requirements.

Metal Plating For Corrosion Resistance On Steel

Electroless Nickel Ams 2404, Astm B733

Because it does not need electric current, electroless nickel plating takes less time than electroplating processes like hard chrome. This type of metal plating improves corrosion resistance by creating a thick, even coating of nickel onto a metal surface. EN can plate down deep recesses of complex shapes. The protective nickel coating has a high hardness and is able to fill any flaws, making it the best metal plating solution for worn or degraded metal parts. Another advantage of electroless nickel plating is that after the plating process is complete, the metal part is ready to go—there’s no need for further surface finishing, grinding, or machining, unlike with other metal finishes.

Manganese Phosphate Mil-dtl-16232 Type M

Manganese phosphate is the hardest type of phosphate coating, and it provides superior corrosion resistance for steel parts. Unlike other phosphate coatings, manganese phosphate can protect steel parts even after they are broken in. Manganese phosphate coatings absorb lubricants on steel surfaces to enhance corrosion resistance and prevent the galling of parts like bearings, bushings, and fasteners that are subject to wear.

Zinc Nickel AMS 2417, ASTM B841

Zinc platings alone have marginal corrosion resistance, but provide even better protection when alloyed with nickel. Zinc nickel plating protects steel, copper, and brass against high temperatures. It can also minimize galvanic corrosion caused by dissimilar metals. This type of metal plating is commonly used in the aerospace industry for landing gears, flap tracks, and other metal parts. It’s also used widely in the defense, automotive, heavy equipment, and agricultural machinery industries. Zinc nickel is a sacrificial coating and is an environmentally safe alternative to cadmium that offers equivalent and, in some cases, better corrosion resistance.
