Mid Phos Electroless Nickel Plating Services

 Mid Phosphorous “Bright” Electroless
Nickel is designed by the manufacturer to
provide a high quality electroless nickel
deposit from a highly stable plating solution at an economical cost. The bath plates
at approximately 0.7-1.0 mil per hour,
depositing a Nickel Phosphorus coating that
is bright in appearance while maintaining
the engineering properties of an Electroless
Nickel plate. The deposit’s corrosion resistance functions as a barrier coating. The
deposit is completely amorphous (no crystal or phase structure). If the deposit is heat
treated, particles of Ni3P will precipitate
and the coating crystallizes, resulting in a
significant increase in the hardness and
wear resistance.
