Thermal Spray Solutions provides a range of coating solutions for a variety of electrical applications including conductivity, resistivity, non-conductivity, and EMI/RFI shielding.
Electrically Conductive Coatings
There are a variety of metals and metal alloys that are proven options to provide different levels of conductivity. Copper is widely used on electrical enclosures as well as aluminum and molybdenum. Conductive coatings can be effective over a broad range of operating temperatures.
Electrically Resistive Coatings
Electrically resistive coatings with high dielectric strength can be applied to form a continuous resistive coating on a component’s surface. Although aluminum oxide is commonly used for this purpose, a number of coating materials are available to solve a variety of electrical problems. Coatings can be applied to both metal and composite substrates.
Electrically Non-Conductive Coatings
Ceramic coatings such as alumina titania can be used to provide non-conductive coatings. An excellent example of Non-Conductive Coatings is the plasma application of a ceramic coating on submarine cable connectors, which prevents corrosion from galvanic action.
Uniform EMI and RFI shielding can be achieved on electronic equipment enclosures by using thermal sprayed copper, aluminum, and zinc. These coatings provide protection to electronic components from electric “noise” produced by electric motors, controls, switches, transformers, etc.
