Thermal Spray
Thermal spray coating involves the use of a torch to heat a material, in powder or wire form, to a molten or near-molten state, and the use of a gas to propel the material to the target substrate, creating a completely new surface. The coating material may be a single element, alloy or compound with unique physical properties that are, in most cases, achievable only through the thermal spray process.
Thermal spray coatings are a highly cost-effective and straight-forward method for adding superior properties and performance qualities to a given engineering surface. The variety of products and coatings that can be enhanced by thermal spray are virtually limitless. The coatings are usually metallic, ceramic, carbides, or a combination of these materials to meet a range of physical criteria.
