2. Bethanization - Wikipedia

   en.wikipedia.org/wiki/Bethanization

   Bethanization is a process patented by the Bethlehem Steel Company to protect steel from corrosion by plating it with zinc, [1] a process similar to electrogalvanization.In advertising materials, Bethlehem Steel claimed the process was more effective than hot dip galvanization, the most common means of using zinc to protect steel.

   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 galvanizing and electroplating. [ 1 ]

4. Electroplating - Wikipedia

   en.wikipedia.org/wiki/Electroplating

   Simplified diagram for electroplating copper (orange) on a conductive object (the cathode, "Me", gray). The electrolyte is a solution of copper sulfate, CuSO 4 in sulfuric acid. A copper anode is used to replenish the electrolyte with copper cations Cu 2+ as they are plated out at the cathode.

5. Cathodic protection - Wikipedia

   en.wikipedia.org/wiki/Cathodic_protection

   Aluminum sacrificial anodes (light colored rectangular bars) mounted on a steel jacket structure. Zinc sacrificial anode (rounded object) screwed to the underside of the hull of a small boat. Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an ...

6. Electrophoretic deposition - Wikipedia

   en.wikipedia.org/wiki/Electrophoretic_deposition

   Certain metals, such as zinc, may become embrittled from the hydrogen gas which is evolved at the cathode. The anodic process avoids this effect since oxygen is being generated at the anode. The major advantages that are normally touted for the cathodic processes are: Higher levels of corrosion protection are possible.

7. Galvanic anode - Wikipedia

   [7] [8] Where this is a concern, zinc anodes may be used. An aluminum-zinc-tin alloy called KA90 is commonly used in marine and water heater applications. [9] Zinc and aluminium are generally used in salt water, where the resistivity is generally lower and magnesium dissolves relatively quickly by reaction with water under hydrogen evolution ...
