Thyristor – Working, VI Characteristics, Types, Applications, Advantage & Disadvantage
A Thyristor is basically an on-off switch to control the output power of an electrical circuit by switching on and off the load circuit in intervals of time
Galvanic Corrosion
Galvanic corrosion may occur in fresh or salt water. It generally happens whenever two/or more metallic elements having unlike galvanic-voltages connects to each other electrically in the presence of an electrolyte. In other words, it can also be said that Galvanic corrosion is an outcome of the usual property of an active metal (greater in […]
Corrosion
It is generally understood that Corrosion means rust and is treated like an almost universal object of hatred. This word ‘Rust’ has been specifically reserved for iron corrosion. However, Not so many knows that corrosion is such a destructive process which affects almost all metals. Since iron is the first and most extensively used metal […]
Importance of Hull protection
If we go back in history, we can understand that the man has involved himself with works and resources of sea from a long time. He has been continuously improving and producing structures for using it in such harsh conditions. Earlier, structures were manufactured by using Iron. After some time, mankind invented steel and started […]
Hull protection methods
Paints alone cannot accord complete protection to underwater hull. Areas above keel blocks are not always possible to protect by painting. Stern areas suffer erosion due to high turbulence caused by propeller. In these areas, chances of galvanic corrosion are more due to presence of bronze propeller which is directly coupled to mild steel hull […]
Theory behind Impressed current cathodic protection
Impressed current cathodic protection is a method for ship’s hull protection. But, before discussing the Impressed current cathodic protection, its important to know the theory and history of cathodic protection. Cathodic Protection is a method of controlling corrosion and is based on electrochemical process. In this method, the corrosion of the cathode is achieved by […]
Cathode Ray Tube (CRT)
Every one must have seen TV/Computer picture tubes. Have you ever thought, How the display on TV screen comes?? Its all because of the CRT ( of any mode) used in them. CRT denotes for Cathode Ray Tube. In any class of CRT, it consists five fundamental parts: Electron Gun Anodes Horizontal deflection plates Vertical […]
