A material is diffused into an electrically conductive substrate to enhance and add desirable properties through a metalliding process employing an electrolytic bath within an atmosphere substantially free of oxygen. The substrate to be coated is submerged within the bath as a cathode along with multiple anodes, each anode having a distinctive composition from the other. A variable power source provides preselected current densities to each of the anodes so as to result in a diffusing of material from each anode for coating the substrate in proportion to the current densities applied to each anode. Products of the invention include an electrically conductive substrate and an alloy coating diffused into a surface of the substrate, wherein the alloy coating comprises a compound of beryllium, boron or silicon, plus at least one refractory metal.
