John Wright (1808–1844) was a surgeon from Birmingham, England who invented a process of electroplating involving potassium cyanide. The process was patented in 1840 by Wright's associate George Richards Elkington. He was born on the Isle of Sheppey, Kent and was apprenticed to a Dr Spearman in Rotherham, Yorkshire.
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 ...
Zinc plating was developed and continues to evolve to meet the most challenging corrosion protection, temperature, and wear resistance requirements. Electroplating of zinc was invented in 1800, but the first bright deposits were not obtained until the early 1930s with the alkaline cyanide electrolyte.
Scheme of Ritter's apparatus to separate water into hydrogen and oxygen by electrolysis. In 1800, English chemists William Nicholson and Johann Wilhelm Ritter succeeded in separating water into hydrogen and oxygen by electrolysis. Soon thereafter, Ritter discovered the process of electroplating.
In 1802, Brugnatelli successfully carried out the first gilding electroplating experiments [4] with the coating of carbon electrodes by a metallic film, finally refining the process in 1805 for which he used his colleague Volta's invention of five years earlier, the voltaic pile, to facilitate the first electrodeposition. He hypothesized that ...
Alexander Parkes was born at Suffolk Street, Birmingham, the fourth son of James Mears Parkes and his wife Kerenhappuch Childs. Samuel Harrison, described by Sir Josiah Mason as the inventor of the split-ring (or key-ring) and widely credited with the invention of the steel pen, was his great-uncle. [6]
Electroplating – the Moche independently developed electroplating technology without any Old World influences. The Moche used electricity derived from chemicals to gild copper with a thin layer of gold. In order to start the electroplating process, the Moche first concocted a very corrosive and a highly acidic liquid solution in which they ...
Luby holding the thin film heads he invented. The challenges to extend the storage technology at that time were: [16] 1, to achieve areal density beyond 3 Megabits per square inch; and 2, to batch fabricate the read/write heads. Romankiw invented several key inventions that enabled the extendibility of the magnetic storage technology. 1.
