| Abstract Scope |
Thermal sprayed cemented carbides are widely used for protecting engineering components used in harsh environments against wear and corrosion. Numerous industries including aerospace, energy systems, heavy machinery, oil/gas extraction etc all reply on these coatings for both protection and sustainability by allowing the underlying structural materials from damage. Tungsten carbide and chrome carbide and primary hard face materials with a range of metallic bindings from Cobalt, Nickel, and mixed alloys such as cobalt chrome, nickel chrome and iron chrome systems. Unlike conventional liquid phase sintered cermets, thermal sprayed coatings rely on inertial impaction and consolidation to form dense coatings and rely on the matrix to support the formation. In this presentation, the role of matrix type and content will be critically addressed through multitude of measurments. The results suggest the importance of higher matrix content for beneficial processing and performance. |
