Manufacture of Nickel-Ceramic Composite Membranes in Agitated Electroless Plating Baths

摘要

Nickel hydrazine electroless plating baths with membrane stirring as a mass transfer enhancement is considered to evaluate the membrane morphological dependence on metal solution concentration, loading ratio (membrane area per unit volume of plating solution), and stirrer speed. Inexpensive sintered ceramic supports with an average pore size of 275Â nm were used for all experimental investigations. Other parametric investigations include conversion and plating efficiency. It was observed that the loading ratio significantly influenced metal film thickness but not the nominal pore size of the membranes. On the other hand, effect of stirrer speed is significant for solutions with 0.04Â mol/L metal solution concentrations, moderate for solutions with 0.08Â mol/L solution concentration, and insignificant for 0.16Â mol/L concentration. Based on several experimental investigations, it is inferred that the optimal choice of the agitated plating process are 0.08Â mol/L initial nickel solution concentration, 393Â cm2/L of loading ratio, and 100Â rpm stirrer speed.View full textDownload full textKeywordsConversion, Densification, Efficiency, Electroless, Hydrazine, Membrane, Plating, StirringRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10426914.2011.557134
