      Substrate is a term used in materials science and engineering to describe the base material on which processing is conducted. Surfaces have different uses, including producing new film or layers of material and being a base to which another substance is bonded.


      Description


      In materials science and engineering, a substrate refers to a base material on which processing is conducted. This surface could be used to produce new film or layers of material such as deposited coatings. It could be the base to which paint, adhesives, or adhesive tape is bonded.
      A typical substrate might be rigid such as metal, concrete, or glass, onto which a coating might be deposited. Flexible substrates are also used. Some substrates are anisotropic with surface properties being different depending on the direction: examples include wood and paper products.


      Coatings



      With all coating processes, the condition of the surface of the substrate can strongly affect the bond of subsequent layers. This can include cleanliness, smoothness, surface energy, moisture, etc.
      Coating can be by a variety of processes, including:

      Adhesives and adhesive tapes
      Coating and printing processes
      Chemical vapor deposition and physical vapor deposition
      Conversion coating
      Anodizing
      Chromate conversion coating
      Plasma electrolytic oxidation
      Phosphate coating
      Paint
      Enamel paint
      Powder coating
      Industrial coating
      Silicate mineral paint
      Fusion bonded epoxy coating (FBE coating)
      Pickled and oiled, a type of plate steel coating.
      Plating
      Electroless plating
      Electrochemical plating
      Polymer coatings, such as Teflon
      Sputtered or vacuum deposited materials
      Vitreous enamel
      In optics, glass may be used as a substrate for an optical coating—either an antireflection coating to reduce reflection, or a mirror coating to enhance it. Ceramic substrates are also used in the renewable energy sector to produce inverters for photovoltaic solar systems and concentrators for concentrated photovoltaic systems.
      A substrate may be also an engineered surface where an unintended or natural process occurs, like in:

      Fouling
      Corrosion
      Biofouling
      Heterogeneous catalysis
      Adsorption
