The recent innovations in dry etching make it a promising technology for the fabrications of micromoulds. The high aspect ratios, directional freedom, low roughness, high etch rates and high selectivity with respect to the mask material allow a versatile fabrication process of micromoulds for subsequent electroplating and embossing, as is demonstrated with the DEEMO process. DEEMO is an English...

n this paper a finite element model has been proposed for evaluation of primary and secondary current density values on the cathode surface in nickel electroplating operation of a revolving part. In addition, the capability of presented electroplating simulation has been investigated in order to describe the electroplated thickness of the nickel sulfate solution. Nickel electroplating experi...

Electroplating pada dunia industri banyak dimanfaatkan akhir-akhir ini dengan tujuan untuk perbaikan penampakan benda kerja yang dilapisi maupun mencegah atau menghambat laju korosi logam. merupakan proses pelapisan logam dilakukan mengalirkan arus listrik searah elektroda-elektroda melalui larutan elektrolit. Tembaga, krom dan nikel biasanya digunakan sebagai pelapis saat electroplating, karen...

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...

Abstract The article presents the possibility of recovering nickel from waste produced as a result wastewater neutralization during electrochemical surface treatment metals. Leaching sludge with concentrated hydrochloric acid enabled metals contained in precipitate to solution efficiency 74.4% (Se) 100% (Zn). content elements was determined using ICP-OES method. next step precipitation obtained...

BACKGROUND High salinity (1-10% w/v) of tannery wastewater makes it difficult to be treated by conventional biological treatment. Salt tolerant microbes can adapt to these saline conditions and degrade the organics in saline wastewater. RESULTS Four salt tolerant bacterial strains isolated from marine and tannery saline wastewater samples were identified as Pseudomonas aeruginosa, Bacillus fl...
