The pulse electroplating or pulse electrodeposition (PED) process involves the swift alternating of the electrical potential or current between two different values, resulting in a series of pulses of equal amplitude, duration, and polarity, separated by zero current. By changing the pulse amplitude and width, it is possible to change the ...
A spoon (UK: / ˈ s p uː n /, US: / ˈ s p u n / SPOON) is a utensil consisting of a shallow bowl (also known as a head), oval or round, at the end of a handle. A type of cutlery (sometimes called flatware in the United States), especially as part of a place setting, it is used primarily for transferring food to the mouth (eating). Spoons are ...
Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
Plastic spoon — cheap, disposable, flexible, stain resistant, sometimes biodegradable; black, white, colored, or clear; smooth, non-porous surface; varied types and uses; Rattail spoon — developed in the later 17th century; with a thin pointed tongue on the bottom of the bowl to reinforce the joint of bowl and handle
Copper electroplating baths can be used to plate either a strike or flash coating, which is a thin highly-adherent initial layer that is plated with additional layers of metal and that serves to improve adhesion of the subsequent layers to the underlying substrate, or a thicker coating of copper that may serve as the finish layer or as a ...
Nickel silver first became popular as a base metal for silver-plated cutlery and other silverware, notably the electroplated wares called EPNS (electroplated nickel silver). It is used in zippers , costume jewelry , for making musical instruments (e.g., flutes , clarinets ), and is preferred for the track in electric model railway layouts, as ...
Such zinc electroplating or zinc alloy electroplating maintains a dominant position among other electroplating process options, based upon electroplated tonnage per annum. According to the International Zinc Association, more than 5 million tons are used yearly for both hot-dip galvanization and electroplating. [ 1 ]
Modern soup spoons are usually stainless steel or silver-plated, but in the past wooden and horn spoons were more common. The idea of including a separate soup spoon in a table setting originated in the eighteenth century, when the bowl shapes varied widely, deep or shallow, oval, pointed, egg-shaped or circular. Spoon shapes became more ...
