<p>Solid inorganic particles and metals are codeposited from electroplating baths to form a coating of a very homogeneous structure, said positively charged resin particles, which have a particle size of less than 300 mu m, being kept dispersed in said baths in the presence of a cationic fluorocarbon surfactant in at least the same weight ratio to the particles in the bath liquid as in an 0,005 N KNO3-solution in which the particles assume a zeta-potential of at least +40 mV with the exclusive use of said cationic fluorocarbon compound.</p> |
