The development of new, advanced-performance hard protection coatings is very important for advancement in a number of science and industrial fields.The use of coatings on products in global manufacturing is now common to minimize production costs and increase profitability, both of which are necessary if the industry wants to stay economically competitive.Hard protective coating can significantly improve parts and system performance in many industrial applications, including aerospace, car, manufacturing, and the other industries, enhancing their service life and saving energy.The material's longevity depends on its quality.High quality materials are intrinsically durable.Durability can be improved by choosing products correctly to suggest, position and heal.One way to enhance durability of material is by the application of a coating.The coated materials have a high hardness than those of the uncoated materials. This review paper discusses various techniques of coatings.
