Abstract:
1. A method for electroplating titanium and titanium alloys into a plastic or carbon foam comprises the steps in combination of: (a) activating of a surface of a substrate to promotes adhesion of a metal, wherein the substrate is a plastic or carbon foam; wherein the activating of the surface of the substrate further comprises the steps: removing of water in the surface of the substrate by a dehydrator solution; conditioning of the surface of substrate by a plurality of first counter flow conditioning rinses; etching of the surface of the substrate is etched by a solution of 20% hydrochloric acid; rinsing of the surface of the substrate is rinsed by a plurality of rinses; activating of palladium in the surface of the substrate by an activator solution; conditioning of the surface of the substrate is conditioned by a plurality of second conditioning rinses; preparing a low catalyst drag-in of the surface of the substrate by an accelerator; conditioning of the surface of the substrate is conditioned by a plurality of third conditioning rinses; (b) depositing of electroless nickel metal to the surface of the substrate; (c) electroplating of titanium and titanium alloys to the surface of the substrate; and depositing of electroless nickel metal onto the surface of the substrate wherein a pH level is maintained at 8.5-9 and a rate of deposition is kept at 0.0001 μm/h.
