A coating material is applied to a moving web of flexible substrate during the coating process. The carrier substrate can be paper, film, or aluminium foil, and the extra qualities of the final material will vary depending on the application and end-use. The composition and processing factors have a big impact on coating application and performance. Coatings with qualities ranging from wholly ceramic to purely organic have quite varied properties, but they can provide crucial benefits to a component. Understanding the operating requirements, as well as candidate application methods and supply chain factors, is necessary for selecting the most appropriate coating type and deposition process.
Surface engineering is a broad term that encompasses a variety of techniques for modifying the surface properties of metallic and non-metallic components for ornamental and/or functional objectives. Improving corrosion and wear resistance to increase component life; making objects more visually appealing; and adding specific features like lubricity improvement, non-stick surfaces, and so on are just a few examples. Surface engineering is a sub-discipline of materials science concerned with solid matter's surface. Chemistry, mechanical engineering, and electrical engineering are among the fields where it can be used (particularly in relation to semiconductor manufacturing).
