The Conditions Of Electroless Plating Are As Follows

The conditions of electroless plating are as follows:

 (1) the reducing potential of the reducing agent in the bath is significantly lower than the potential of the deposited metal, so that the metal may be reduced and deposited on the substrate. (2) The prepared bath does not produce spontaneous decomposition, when it is in contact with the catalytic surface, the metal deposition process occurs. (3) When the pH value and temperature of the solution are adjusted, the reduction rate of the metal can be controlled, so as to adjust the plating rate. (4) The metal precipitated by reduction also has catalytic activity, so that the REDOX deposition process can continue, and the coating can be continuously thickened. (5) The reaction products do not hinder the normal process of plating, that is, the solution has enough service life. There are many kinds of metals and alloys covered by electroless platings, such as Ni-P, Ni-B, Cu, Ag, Pd, Sn, In, Pt, Cr, and a variety of Co-based alloys, but the most widely used are electroless nickel and copper plating. The chemical coating generally has good corrosion resistance, wear resistance, brazing, and other special electrical or magnetic properties, so the surface treatment process can be very good to improve the surface properties of the material.
