A key fob is a generally decorative and at times useful item many people often carry with their keys, on a ring or a chain, for ease of tactile identification, to provide a better grip, or to make a personal statement. Key fob can also specifically refer to modern electronic car keys, or smart keys, which serve as both a key and remote.
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 ...
An example of this regulation being a fifteenth century law from Germany that prohibited women from displaying more than one gold chain at a time. [ 4 ] By the end of the period, the types of personal jewelry worn by wealthy women were not very different from those found today, with rings, necklaces, brooches, lockets and (less often) earrings ...
Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. [ 3 ] To clean and protect the part during the plating process, a combination of heat treating , cleaning, masking, pickling , and etching may be used. [ 1 ]
The electric current causes copper atoms to dissolve from the anode's surface and to enter the electrolyte as copper ions (Cu ++ in the figure). Copper ions are taken up by the mold's conducting surface at the same rate at which copper dissolves from the anode, thus completing the electrical circuit. [ 11 ]
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.
Women in Roman Britain wore 'chatelaine brooches' from which toilet sets were suspended. [6] The remnants of chatelaines and chatelaine bags have been found in the graves of women in the seventh and eighth century in the United Kingdom. Often found with the chatelaine artifacts would be wire rings, beads, buckles, knives and tools. [7]
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.
