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)
Aerospace: wear resistance of components, corrosion protection, chemical resistivity and lubricity on valves, pistons, engine shafts, engine mounts, compressor blades and other flight-critical components.
Telecommunications: solderability and conductivity properties.
Transport: chemical resistance.
Plastics Manufacturing: durability and release properties on injection molds and extrusion dies.
Automotive: wear protection and corrosion resistance on pistons, cylinders, gears, differential pinon ball shafts, fuel injectors, ball studs, transmission thrust washers, knuckle pins, hose couplings, heat sinks and others.
Stainless Steel Replacement: cost effective replacement for 300 and 400 series stainless steel in some applications
