Functional Trivalent Chromium Electroplating of Internal Diameters
This paper discusses recent research work on the development of a functional trivalent chromium plating process from a trivalent-based electrolyte to replace hexavalent chromium plating. Hexavalent chromium plating has been used for many years to pr...

Corrosion-Current Data for Nickel-Chromium Couples
When nickel electroplate is coupled with chromium, a high current density and corrosion rate at the anode, usually nickel, are favored by a high electrolyte concentration, a high temperature and a low nickel-to-chromium area ratio.

Electroplating of Zinc-Base Die Castings in a System Incorporating Dual Chromium
In the CASS testing of 1961 outside door handles plated in one of six exterior die-cast plating machines equipped for the dual chromium system at the Flint, Michigan plant of the Ternstedt Division of General Motors Corporation, 97% of the handles t...

Growth of ZnO Nanorod Arrays on Flexible PDMS Substrates
In this work, well-aligned zinc oxide (ZnO) nanorods were successfully deposited on flexible polydimethyl-siloxane (PDMS) substrates by a simple hydrothermal growth method. The low temperature (<100°C) synthesized ZnO nanorods were investigated by s...

Stripping Metallic Coatings
The stripping of electrodeposited and flame-sprayed coatings is a necessary part of surface finishing. Stripping may be required to allow for the re-plating of a part rejected due to defective finishing or as part of rework processes such as those c...

Characterization of Electroless Deposition of Ni-P-Al2O3 and Ni-P-TiO2 from Alkaline Hypophosphite Baths in the Presence of Gluconate as a Complexing Agent
Electroless deposition of Ni-P-Al2O3 and Ni-P-TiO2, in the presence of gluconate as a complexing agent, on copper substrates was studied. The dependence of the composite formation on different plating variables was investigated. The deposited coatin...

Investigation of Tin Whisker Formation
Immersion tin and lead-free hot air solder leveling (HASL) coatings based on SnCu or SnAgCu alloys are widely used as surface finish materials for printed circuit boards (PCB). These coatings prevent the underlying copper from corrosion and preserve...
