Abstract

A group 1B metal, e.g. copper is electrolessly deposited from a solution pH 10 to 14 comprising (moles 1 litre) 0.002 to 0.6 water soluble metal salt, 0.002 to 2.5 alkali metal borohydride or amine borane, and a complexing agent in an amount between 0.7 and 10 times the moles of the water soluble salt. In an example a solution comprises copper sulphate 0.05 moles/1., E.D.T.A.0.12 moles 1 litre, sodium cyanide 0.008 moles/1., and sodium borohydride 80 mg/1. The substrate may be Ni, Co, Fe or steel, Pd, Pt, Cu or brass, Mn, Cr, Mo, W, Ti, Sn, Ag paper, glass, ceramic or plastics. A surfactant, e.g. organic phosphate esters or oxyethylated sodium salts may be present up to 5 g.11.
