Spray powder refers to fine, engineered powders used as feedstock materials in thermal spray processes, where they are heated and propelled onto a surface to form a coating. These powders are typically composed of metals, ceramics, cermets, or alloys and are designed to enhance surface properties such as wear resistance, corrosion protection, thermal insulation, or electrical conductivity.
Key characteristics of spray powders:
Available in various compositions (e.g., tungsten carbide, chromium oxide, nickel alloys)
Common applications include:
Corrosion- and wear-resistant coatings in harsh environments
Proper powder selection is critical for achieving optimal coating performance, adhesion, and durability.
