Mspecs offers two different processes: Electroless Nickel plating and Electroplated Nickel to ensure optimal finishes on varied products.
Electroless Nickel is an auto-catalytic chemical technique used to deposit a layer of nickel-phosphorus ferrous and non-ferrous metals. The process relies on the presence of a reducing agent, for example hydrated sodium hypophosphite (NaPO2H).
Electroplated Nickel offers a versatile coating that uses 99.9% pure nickel and requires an electric current to plate the part to achieve the desired finish/plating thickness.
High Phosphorus (10% and above): superior corrosion protection; most resistant to acidic environments; greater than 65 Rc hardness with post-plate thermal treatment; amorphous deposit structure
Medium Phosphorus (5% to 9%): best appearance; mixed amorphous/crystalline deposit structure
Plating thicknesses from 0.0001 to 0.0010 inches
Precision masking for selective plating
Salt spray corrosion testing per ASTM B117
Post-plate hydrogen embrittlement relief
Hardnesses up to 70Rc (high phosphorous with post-plate bake)
Thickness Analysis
