Aluminum-manganese alloy coatings were electroplated onto carbon steel by using AlCl3+LiAlH4+MnCl2 organic solvent electrolyte,and the surface morphology,composition,structure,thickness,adhesion and corrosion resistance of Al-Mn alloy coatings were observed and determined.
The optimum deposition parameters for Al-Mn alloy coatings in organic solvent electrolyte are the current density of 0.15 to 0.50 A/dm2 and deposition time of 30 to 45 min.
Al-Mn合金镀层在AlCl3+LiAlH4+MnCl2有机溶剂体系中的最佳沉积工艺为电流密度0.15-0.50 A/dm2、电镀时间30-45 min.
Cyanide-free electroplating baths for deposition of gold and gold alloy coatings, using sulphurous gold complexes that are stable for a relatively long time, can be used with current density over 1 A/dm2 and are practically odor-free, are obtained when the sulphurous compounds used are mercaptosulfonic acids, dye sulfide sulfonic acids or salts thereof.
A Rutherford backscattering (RBS) technique, x-ray diffraction microanalysis of phase composition, diffraction transmission electron microscopy (TEM), and hardness and adhesion measurements were used to examine the hard-alloy coating.
Electrochemical behavior of cobalt in a tungstate melt, as well as the effect of electrolysis conditions on the composition and structure of cobalt-molybdenum (tungsten) alloy deposits from tungstate-molybdate melts is studied.
The anomalous codeposition of iron is minimized and the quality of the alloy deposits is improved with the combination of sodium citrate and glycolic acid.
Objective: To study the techniques of placement of memory alloy plating gold biliary stent and plastic stent for palliation of malignant and benign biliary obstruction, and to assess its clinical effectiveness.
Conclusion: Memory alloy plating gold biliary stent and plastic stent were safe and efficacious methods for malignant and benign biliary obstruction, and could improve patient's living quality.
Electrodeposition of the single-phase β'-brass superlattice at underpotentials of Zn in Cu-Zn alloy plating is explained by an accumulative underpotential deposition (UPD) mechanism.
