Anodic Protection is an electrochemical technique used to prevent corrosion on metals which exhibit a passive behavior in highly acidic or alkaline environments. Anodic Protection is commonly found on Sulfuric Acid tanks and Kaymr Digesters.

Write differences between Anodic Coatings and cathodic coatings?
In anodic system, small amounts of the metal migrates into the coating film limiting it's usefulness in corrosion protection. Anodic coatings are used in less severe environments and are generally economical and produce a nice surface finish. Cathodic systems produce an coating free of metal migration and are much more robust. These systems are useful in heavy corrosive environments.
What is the Anodic index of stainless steel?
There is not a straight forward answer. There are many grades and variants of Stainless steel. The highest contributor to the Anodic index of stainless steel is the amount of Chromium in the different grades. Taking this into consideration, High Chromium content Stainless Steel would have an Anodic index of around 0.50, whiles the lowest grade stainless steel variants would have an Anodic index of around 0.85.
What is the process called to thicken the oxide layer on aluminium?
Anodizing. Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish.
Why does part of a nail inside the wood undergoes corrosion easily?
The part of the nail inside the wood is not exposed to atmospheric conditions, whereas the remainder part of it is exposed directly to atmospheric air. due to differential aeration, the nail inside the wood (not oxygenated part) becomes anodic, while the upper part of nail (well oxygenated) becomes cathodic. Consequently, a differential current starts flowing, whereby the anodic part (nail inside the woo) gets corroded easily.
How is metal formed?
Abstract of the Disclosure A method for the electrolytic production of metal, includes electrolyzing, between anodic and cathodic surface areas, a compound of the metal dissolved in a molten solvent, the electrolyzing being performed at a temperature such that the metal is formed in the molten state, the metal collecting in a molten metal pad, wherein the improvement includes the provision of cathodic surface area in the form of an array of elements protruding out of the pad into the melt toward the anodic surface area for establishing a series of locations at which the anode-cathode distance is up to 1-1/4 inches

What does blast protection do in Minecraft?
Blaze protection, or fire protection is an enchantment applied to armor. It reduces the amount of damage done by fire and lava.
Why would you do if you gave a piggyback ride to someone and They felt nervous and peed but was wearing protection?
What can you do? What's done is done! I suppose you should just be thankful that they were wearing protection!
Why anodic inhibitors are not satisfactory?
there is a certain critical concentration of solution above which inhibition may be experienced... when an insufficient concentration is used all the anodic areas may not be covered, as a result it leads to increase in current density at that place......hence, it can be dangerous..if not used in right concentration...
