==Issue at Hand = Areas Of Application === [[Image:Cadmium Consumption.jpg]] == Regulatory Concerns == The Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment 2002/95/EC (commonly referred to as the Restriction of Hazardous Substances Directive or RoHS) was adopted in February 2003 by the European Union.The RoHS directive took effect on 1 July 2006, and is required to be enforced and become law in each member state. This directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment. It is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC which sets collection, recycling and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of huge amounts of toxic e-waste. * '''It restricts the use of the following six substances:''' 1. Lead (Pb)<BR>2. Mercury (Hg)<BR>3. '''Cadmium (Cd)'''<BR>4.''' Hexavalent chromium (Cr6+)'''<BR>5. Polybrominated biphenyls (PBB)<BR>6. Polybrominated diphenyl ether (PBDE)<BR> Thus,Is id evident that cadmium is Losing its place in Industrial Usage.Thus, it becomes imperative that there is a need for finding out alternative technology can can replace cadmium and provide similar features which will be more environment friendly. * '''Other Issues Related to Use of Cadmium.'''1. Cadmium is a toxin for both animals and plants. 2. Cadmium is known to sublimate in a hard vacuum environment .The sublimation products, which are conductive, can redeposit resulting in short circuits. The sublimation products may also interfere with sensitive optics. 3. Cyanide solutions used in Cadmium plating are highly Toxic. 4. Cadmium is subject to the spontaneous growth of Cadmium whiskers. Cadmium whiskers (like tin whiskers) grow spontaneously and are capable of causing electrical failures ranging from parametric deviations to sustained plasma arcing that can result in catastrophic short circuits. == Rationale ==[[Image:Chromium spring image.jpg|thumb|right|350px|Cadmium plating]]
* It is very difficult to ensure complete protection of steel from corrosive environment at temperatures as high as 900°F.
* Traditionally used Ni-Cd Coatings involve use of Hexavalent chromium, cadmium and cyanides which are very toxic. Thus, making it difficult to ensure safety of the work environment.
* US6869690B1 [http:- This patent shows how Ni-Zn can be used to replace NI-Cd for Corrosion/Heat resistance/en.wikipedia.org/wiki/Restriction_of_Hazardous_Substances_Directive RoHS] disallows use of cadmium in electrical equipment.
* US7018486B2 :-This patent Proposes Use Cadmium is subject to the spontaneous growth of environment friendly Trivalent Chromium Instead Cadmium whiskers. Cadmium whiskers (like tin whiskers) grow spontaneously and are capable of hazardous hexavalent Chromium causing electrical failures ranging from parametric deviations to enhance the anti-corrosive strength if the coatingsustained plasma arcing that can result in catastrophic short circuits.[http://www.finishing.com/100/89.shtml Source]<BR><BR>
* Provides sacrificial Protection to the steel Not just an idea but a patented & experimentally proven technology. Pratt&Whitney also as in case has a working prototype of cadmiumthe technology.
* Offers equivalent or superior protection to the baseline NiCd coatingsNot very capital intensive, as it utilizes already established processes used for electroplating.
* 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 A green technology eliminating the volume use of hazardous waste, and decreases the amount of cadmium and cyanide at in 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 coating process types may require an industrial wastewater discharge permit (local issue).
== Area of Application Areas == * Coating material for steel surfaces and certain other metals like aluminum and copper which might be exposed to highly corrosive atmosphere and extremely high temperatures. == Electrical Transmission Industry == [[Image:Electrical connectors Cadmium1Area of Application.jpg|thumb|right700px|350pxcenter|Electrical Connectors Used in Military Application]]The elimination Area of cadmium on electrical connectors presents a unique problem not applicable to other components. Items such as fasteners, washers, etc. use cadmium primarily for its corrosion resistance and lubricity. Although these properties are equally important on electrical connectors, the connector shell materials must also provide electromagnetic and radio frequency interference (EMI/RFI) protection. This protection is gained by maintaining an electrically conductive pathway across the connector interface. Suitable alternatives for cadmium must have similar corrosion resistance, lubricity and electrical conductivity. <BR><BR><BR>== Fasteners ==[[Image:Fastners cadmium.jpg|thumb|right|350px|Fasteners Used in Aerospace IndustryAplication]]Cadmium plating is banned as far as fasteners are concerned,you need to take special permission and abide to local norms of effluent treatment for cadmium plating to be practiced.Zinc Alloy plating is of great help-Zinc/Nickel deposits from these baths, with the appropriate chromate conversion coating can withstand well over a thousand hours of Neutral Salt Fog testing.<BR><BR><BR><BR><BR> <BR><BR><BR><BR><BR><BR><BR>
== Automotive Parts Legal Status ==[[Image:countrywise filing.jpg|thumb|700px|center|Geographic Spread]]
[[ImageMedia:Automotive parts cadmiumOriginal patent document.jpgpdf|thumb|right|350px|Parts used in Automotive IndustryClick here to download the original patent document]]There is an impending EU restriction on lead, cadmuim, hexavalent chrome, and mercury in vehicles.This EU restriction affects vehicles globally since car manufacturers will have to change all components if some fall under this guideline. All major auto manufacturers are now coming up with guidelines and specifications for this transition.
