Abstract:(prepared by KAKISAWA)
Professor Sanjay Sampath has expanded the conventional view of thermal spray from a coating process to a versatile layered manufacturing process. Thermal spray is not limited to depositing protective coatings on existing components; instead, it is regarded as a manufacturing platform capable of building materials, structures, and functions through controlled layer-by-layer deposition. A key advantage of this approach is the ability to control not only geometry, but also material composition, microstructure, and functionality during deposition. By increasing the deposited thickness, thermal spray can be extended from thin coatings to thick deposits, near-net-shape structures, and even free-standing components. It can also be used for additive repair and remanufacturing of damaged components. Another important feature is multi-material manufacturing. By changing feedstock materials or their mixing ratios during deposition, metallic, ceramic, and composite layers can be combined. This enables the fabrication of functionally graded materials (FGMs), in which composition and properties gradually change through the thickness, reducing thermal and mechanical mismatch between dissimilar materials.
Sampath’s research has further extended thermal spray and direct-write technologies toward functional surfaces, sensors, and electronic structures. This opens the possibility of integrating structural, protective, thermal, electrical, and sensing functions within a single component.
