The objective of the present study was to laser process a refractory metal – refractory carbide alloy based on W-Ti-C ternary system for severe service applications. The key concept was to cast a eutectic alloy of tungsten and titanium carbide/carbonitride straight from the melt through laser materials processing route. In the present study, a W-Ti-C ternary alloy has been laser processed into three-dimensional objects and surface protective coatings. Two novel fabrication systems were designed to build three-dimensional objects, namely tower nozzle solid freeform fabrication system and axis-symmetric laser powder deposition system. W-Ti-C alloy based protective coatings were deposited on graphite substrates, through laser melting of pre-placed powder mixture, to widen the use of carbon structural elements for high temperature applications. A method for depositing W-Ti-C alloy on steel using multi-intermediate layers strategy is discussed and the preliminary results are presented in this study.
