With any great voyage of discovery the explorer should always be asked at the outset “Why are you doing this?” To answer the question “Why use ionic liquids for electrodeposition?” it is first necessary to look at current best practice and find its limitations. It is widely recognised that in 1805 Italian chemist, Luigi Brugnatelli made the first experiments in what we now know as electroplatin...

~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...

Fused Deposition Modeling (FDM) is a kind of Rapid prototyping (RP) technique, which allows direct transformation of CAD files into physical models. This paper attempts to identify and study the influence of electroplating layer thickness on the mechanical strength of Acrylonitrile butadiene styrene (ABS) samples developed from the FDM process. The study is conducted on the tensile test samples...

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...

Experimental investigations have been performed to determine the effects of nicotiana tobaccum (tobacco) extract additive on the electrodeposition of zinc on mild steel in acid chloride solution. The experiments were performed under different plating time, different additive concentrations and fi xed pH conditions. Zinc electrodeposition on mild steel was performed using a DC – supply at defi n...

The use of lithography and electroplating to fabricate variable-reluctance, nearly planar, integrated minimotors with 6-mm-diameter rotors on silicon wafers is described. The motors consist of six electroplated Permalloy@ horseshoe-shaped cores that surround the rotor. Copper coils are formed around each core. The Permalloy and copper electroplating baths, electroplating seed layers, and throug...

Water is prime requirement for surviving of any living beings.  The existence of surface water and groundwater sources are used for domestic, agriculture and industrial purposes in all over the world. Fresh water from both the water sources is highly contaminated in recent years because of rapid population growth, modern agriculture and industrial growth. Among them, contamination of water sour...

One of the problems electroplating industry is periodic discharge concentrated spent electrolytes together with rinsing wastewater. This leads to irreversible loss valuable components, as well risk heavy metal ions entering environment, which have toxic, mutagenic, and carcinogenic effects. The paper presents research on processing from zinc, nickel, copper, cadmium plating, collected over 3 ye...
