== Solution to the Problem ==
=== Patent Portfolio ===
* US6869690B1 :- This patent shows how Ni-Zn can be used to replace NI-Cd for Corrosion/Heat resistance.
* US7018486B2 :-This patent Proposes Use of environment friendly Trivalent Chromium Instead of hazardous hexavalent Chromium to enhance the anti-corrosive strength if the coating.
* US6757134B2 :-This patent explains a method of forming a thin film of high density on the substrate in order to remove any voids or grooves which might initiate corrosion.
=== Benefits ===
* Environmentally friendly alternative to NiCd.
* Eliminates Materials of Concern from the product such as Cadmium, hexavalent chromium and Cyanide from the plating process.
* Provides sacrificial Protection to the steel also as in case of cadmium.
* Offers equivalent or superior protection to the baseline NiCd coatings.
* Chemicals used in cadmium and cyanide processes are toxic to humans and are strictly regulated by local, state, and federal agencies. Replacing those processes with a non-cadmium/cyanide process reduces the volume of hazardous waste, and decreases the amount of cadmium and cyanide at the facility. The reduction of hazardous waste helps facilities meet the requirements of waste reduction under RCRA, 40 CFR 262, Appendix. It may also help facilities reduce their generator status and lessen the amount of regulations (i.e., recordkeeping, reporting, inspections, transportation, accumulation time, emergency prevention and preparedness, and emergency response) they are required to comply with under RCRA, 40 CFR 262. In addition, this technology allows facilities to eliminate cadmium and cyanide bath solutions, so there is less chance that the facility would exceed reporting thresholds for cadmium and cyanide under SARA Title III (40 CFR 300, 355, 370, and 372; and EO 12856). Both process types may require an industrial wastewater discharge permit (local issue).
