Membrane electrolysis (ME) is the only commercial technology using ion-exchange membranes for chromic acid recycling and recovery. On one hand, the technology has a number of promising advantages, but on the other hand, it has not yet gained common acceptance probably due to a lack of operation stability and efficiency. Published results of the research can be divided into three categories: lab...
متن کاملAlternatives to hard chromium plating on piston rods
As a main part of hydraulic cylinder, the piston rod is used in tough surrounding and corrosive condition; consequently a high quality protecting layer is essential. Currently EHC, electroplating hard chromium (hard chrome) is a widespread method for piston rod due to powerful performance and low cost. Unfortunately the plating process contains hexavalent chromium (Cr) which is toxic and carcin...
متن کاملAn epidemiological study on lung cancer among chromium plating workers.
High risk of lung cancer among chromate workers have been reported by many investigators, but it has been limited to the refining process. A recent report demonstrated that there was a significantly high number of deaths from cancer among chromium platers. In this report, a cohort study was carried out on platers in Tokyo. Among 952 chromium platers who were followed up from April 1, 1970 to Se...
متن کاملAn Improved Plating Process
Microtubes, are a basic component for a myriad of potential products. They are very small tubes (hundreds can fit ina human hair) that can be made from practically any material. Tubes larger than 1 micron diameter can be made withany cross-sectional shape desired. The significance of microtubes and microtnbe composites is that they provide theopportunity to miniaturize (even to the ...
