Seedless electroplating on patterned silicon
Nickel thin films have been electrodeposited without the use of an additional seed layer, on highly doped silicon wafers. These substrates conduct sufficiently well to allow deposition using a peripherical electrical contact on the wafer. Films 2 μm thick have been deposited using a nickel sulfamate bath on both n+and p+-type silicon wafers, where a series of trenches with different widths had ...
متن کاملRemoval of Zn2+ from Electroplating Wastewater Using Modified Wood Sawdust and Sugarcane Bagasse
This paper describes the preparation of new adsorbents derived from sugarcane bagasse and wood sawdust Manilkara sp. to remove zinc II ions from electroplating wastewater. The first part deals with the chemical modification of sugarcane bagasse and wood sawdust, using succinic anhydride to introduce carboxylic acid functions into the material. The obtained materials modified sugarcane bagasse M...
متن کاملChrome Electroplating Waste BAT
During the past several years, waste produced by the electroplating industry has attracted attention due to the level of pollutants found in the waste stream, the difficulty associated with treatment, and the cost of waste disposal. EPA has enacted regulations to control the discharge from plating facilities and estimates that 140 million lb of metal pollutants will be prevented from being disc...
متن کاملTreatment of Electroplating Wastes
~sing of the environment, the electroplating industry is likely to be one of the industries to be affected by the introduction of the water pollution control legislation in Hong Kong. The effect may be even more pronounced for the operators of small and medium-sized electroplating factories since they are unlikely to have any expertise in pollution control and will therefore require outside tec...
متن کاملElectroplating of Ni4W
Nickel-tungsten alloys were electrodeposited on stationary working electrodes from a nickel sulfate, sodium tungstate, and tri-sodium citrate-based bath under different operating conditions. The microstructure of the deposits was studied by X-ray diffraction, the morphology by scanning electron microscopy and atomic force microscopy, and the approximate composition by energy dispersive spectros...
