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,… … Wikipedia
Vacuum engineering — deals with technological processes and equipment that use vacuum to achieve better results than those run under atmospheric pressure. The most widespread applications of vacuum technology are: * Pyrolytic Chromium Carbide Coating * Antireflecting … Wikipedia
Vacuum deposition — Not to be confused with Vacuum coating. Vacuum deposition is a family of processes used to deposit layers atom by atom or molecule by molecule at sub atmospheric pressure (vacuum) on a solid surface. The layers may be as thin as one atom to… … Wikipedia
