Substrate (materials science)
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
deposited coatings. It could be the base to which paint, adhesives, or adhesive tape
is bonded.
A typical substrate might be rigid such as
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[2]
- 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[3]
- Industrial coating
- Silicate mineral paint
- Fusion bonded epoxy coating (FBE coating)
- Pickled and oiled, a type of plate steel coating.
- Plating
- Teflon
- Sputtered or vacuum deposited materials
- Vitreous enamel
In
antireflection coating to reduce reflection, or a mirror
coating to enhance it.
A substrate may be also an engineered surface where an unintended or natural process occurs, like in:
