Brush electroplating has several advantages over tank plating, including portability, the ability to plate items that for some reason cannot be tank plated (one application was the plating of portions of very large decorative support columns in a building restoration), low or no masking requirements, and comparatively low plating solution ...
Various manufacturers, such as car companies and their suppliers, have produced their own specifications and supply rules in order to define the requirements for these coating systems. Zinc flake coating is a generic term for the coating technology and this is marketed by the different suppliers under their respective brand names.
At the time of the company's founding the electroplating industry was in its infancy. At that time, the company's main focus was in finishing cast-iron cookware , polishing the chrome on wood-burning stoves , and plating metals used in other products like locomotives , automobiles , and iceboxes .
Electroless nickel-phosphorus is used when wear resistance, hardness and corrosion protection are required. Applications include oilfield valves, rotors, drive shafts, paper handling equipment, fuel rails, optical surfaces for diamond turning, door knobs, kitchen utensils, bathroom fixtures, electrical/mechanical tools and office equipment.
Excluding the continuous strip plating industry, copper is the second most commonly-plated metal after nickel. [6] Copper electroplating offers a number of advantages over other plating processes, including low metal cost, high-conductivity and high-ductility bright finish, and high plating efficiency.
The plating of zinc was developed at the beginning of the 20th century. At that time, the electrolytic solution was cyanide-based. A significant innovation occurred in the 1960s with the introduction of the first acid chloride-based electrolyte. [2] The 1980s saw a return to alkaline electrolytes, only this time, without the use of cyanide.
Recent revisions of ASTM B633 defer to ASTM F1941 for zinc plating mechanical fasteners, like bolts, nuts, etc. 2019 is the current revision for ASTM B633 (superseded the revision from 2015), which raised required tensile thresholds when confronting hydrogen embrittlement issues and addressed embrittlement concerns in a new appendix.
Electroless deposition is an important process in the electronic industry for metallization of substrates. Other metallization of substrates also include physical vapor deposition (PVD), chemical vapor deposition (CVD), and electroplating which produce thin metal films but require high temperature, vacuum, and a power source respectively.
