Study on Developments in Protection Coating Techniques for Steel

Steel, also known as iron alloy, is found 35% of the whole mass Earth. It in many applications due to its unique properties. Alloying elements provide backbone support for iron, improving mechanical, physical, chemical, and structural Failure steel chemical reaction i.e., corrosion, it unavoidable, but can be prolonged. Applications such marine have a salt corrosive environment. High-temperature power plants, gas turbines components, combustion engine components accelerate air oxidization at higher temperatures. Protection coating alters composition alloy surfaces by using techniques like conversion coating, mechanical alloying, ion beam implantation, laser cladding, thermochemical treatments. coatings adhere surface prevent from direct contact with environment, which formed vapor deposition, physical electroplating, bath, sol-gel, thermal spraying, hot-dip coating. These are used reduce accelerated corrosion environments so that life span further enhanced, thereby decreasing replacement cost. methods materials play vital role other corrosion-associated failure protection. The chromium cadmium produce carcinogenic gases. Coating treatment by-products affect environment releasing pollutants. essential choose do not influence ecosystem. In this work, processing available prepare protective discussed. enhance properties various real-time characterizations addition, challenges opportunities proposed scope included.
