A coating is a covering that is applied to the surface of an object, or substrate. [1] The purpose of applying the coating may be decorative, functional, or both. [ 2 ] Coatings may be applied as liquids , gases or solids e.g. powder coatings .
Polymeric coatings are another area of applied grafting techniques. In the formulation of water-borne paint, latex particles are often surface modified to control particle dispersion and thus coating characteristics such as viscosity, film formation, and environmental stability (UV exposure and temperature variations).
Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve ... reflective nature of the coating process. [7 ...
Surface engineering is the sub-discipline of materials science which deals with the surface of solid matter. It has applications to chemistry , mechanical engineering , and electrical engineering (particularly in relation to semiconductor manufacturing ).
Sample polymer brush. In materials science, a polymer brush is the name given to a surface coating consisting of polymers tethered to a surface. [1] The brush may be either in a solvated state, where the tethered polymer layer consists of polymer and solvent, or in a melt state, where the tethered chains completely fill up the space available.
A polymer coating is a form of plastic coating or surface coating and consists of a plastic base. There are also tribological polymer coatings that can be adapted to numerous application needs thanks to the variety of polymers available. [3]
Surface modification is the act of modifying the surface of a material by bringing physical, chemical or biological characteristics different from the ones originally found on the surface of a material. [1] This modification is usually made to solid materials, but it is possible to find examples of the modification to the surface of specific ...
The surface may not heat up significantly, allowing the coating of flammable substances. Coating quality is usually assessed by measuring its porosity, oxide content, macro and micro-hardness, bond strength and surface roughness. Generally, the coating quality increases with increasing particle velocities
