Abstract
Coatings are multifaceted having raw materials combined and utilized to a prepared substrate by allowing it to be dried and cured to obtain effectiveness. Majority of coating challenges occurs in coating manufacturing and its application in different environment not shielded away from the impact of rain, sunlight, wind, heat, cold, humidity, and oxygen. Few coatings, including those applied in marine, aerospace, automobile and medical cannot resist some difficulties arising from corrosion. This paper focuses on identifying the challenges in marine, aerospace and automobile. In marine, the antifouling coating at the watertight body of the ship destroy organisms before they get close to it. Tributyltin (TBT), which is released to the ocean or the sea happens to be the most effective compound used for antifouling coating but its pose serious problems to marine organism due to its toxic substance .In automobile, application of chromium coating is the main source of exposure for workers leading to sneezing, headache, skin irritation, ulcers and respiratory disorder because of its ions that comes in contact with the environment in form of chromate and dichromate anions from the sewage while in aerospace ,movements of a aircraft structural joint would deform, elongate the coating system making the structural component of the aircraft coating system a major challenge in determining aircraft joint displacement. The essence of identifying coatings challenges is to find measure of ensuring substrate are improve in terms of ;appearance, bonding, moisture ability, resistance to wear etc. Hard chromium coated constituents can now find application in agricultural equipment’s, aircraft industry, automobile, marine and other industries.
