'''Coating''' is a covering that is applied to the surface of an object, usually referred to as the '''substrate'''. In many cases coatings are applied to improve surface properties of the substrate, such as appearance, adhesion, wetability, corrosion resistance, wear resistance, and scratch resistance. In other cases, in particular in printing processes and semiconductor device fabrication (where the substrate is a wafer), the coating forms an essential part of the finished product. | '''Coating''' is a covering that is applied to the surface of an object, usually referred to as the '''substrate'''.
