Thermal Spray Overview

Thermal spray is a process of depositing molten, semi-molten, or solid particles onto a substrate to form a functional coating or a freestanding part. The particles travel at high velocity, causing them to flatten on impact with the substrate.

These flattened particles, known as “splats,” build up to form the final coating or part. Thermal spray coatings are used in a number of industries because they offer benefits including corrosion resistance, increased conductivity, wear reduction, repair of damaged surfaces, thermal insulation, electrical insulation and biological functions such as bio-activity.
