Selective chroming

A final injection molded assembly and process for making same that eliminates paint and reduces areas of wasted chrome material. The final injection molded assembly has at least one first injection molded part of a non-plateable first material, at least one overmolded part of plateable second material, at least one pathway through the assembly and integrated features operable for selectively applying an electric current. The pathway creates a predetermined surface path arrangement for applying chrome to desired predetermined plateable areas. A shot of each material is delivered to an injection molding rotary device to produce the injection molded assembly which is then affixed to a chroming process line where electric current is applied. As the electric current is applied and chrome is delivered only the plateable second material will accept the chrome.

An example method of coating a substrate involves cleaning the substrate and, after cleaning the substrate, sensitizing the substrate using a sensitizing solution including tin chloride and hydrochloric acid. The method also involves, after sensitizing the substrate, activating the substrate in an activating solution including palladium chloride and hydrochloric acid. Further, the method involves subsequently neutralizing the substrate using a neutralizing solution including ammonium hydroxide. Still further, the method involves, after neutralizing the substrate, depositing an electroless nickel layer on the substrate. The method may then involve depositing an electrolytic nickel layer on top of the electroless nickel layer, and depositing an outer layer of metallic material, ceramic material, polymeric material, or any combination thereof on top of the electrolytic nickel layer.

MANUFACTURING ENHANCED GRAPHITE METALLIC BIPOLAR PLATE MATERIALS

The present invention includes methods of manufacturing a metal infused graphitic material. Also described is how this device may be rendered impermeable. The present invention includes the electroplating/electroless deposition of metal on exposed internal and external surfaces of a porous graphitic substrate. The deposition of metal on the internal structure is accomplished by replacing the void space in the porous substrate with an electrolyte solution containing dissolved metallic species. The plating is initiated either through electrochemical means, electroless means, chemical vapor deposition means, or other means obvious to one familiar in the art of metal plating. A post-deposition bath is also described wherein the plating may be removed from one or both sides of the external surface without impacting the internal pore plating.
