Thermal Spray Powders are powders of a specific grain size that are sprayed onto a substrate. The powders are propelled by a gas through a high temperature torch that heats the powder to its melting point, where it attaches to the substrate creating a uniform coating on the substrate. The coatings are used to add or alter the properties of the substrate. Washington Mills manufactures a variety of high quality powders that are used in thermal spray applications. We also specialize in creating custom fused materials for special thermal spray applications. Please contact us today if you are interested in learning more about our customized solutions.
