Development of Stellite alloy composites with sintering/HIPing technique for wear-resistant applications
AbstractCobalt-based superalloys, Stellite 694 and Stellite 712, composites were developed with the reinforcement of titanium-carbide particles for wear-resistant applications. The specimens were fabricated using the powder metallurgy technique, combined with hot isostatic pressing. Calorimetric effects of the alloy powders were investigated using the differential scanning calorimetry technique, which provided the theoretical basis of designing the sintering cycles. The phases formed in the microstructures were analyzed using the scanning electron microscope (SEM) and energy dispersive X-ray spectrum (EDS) techniques. The wear test was conducted on a ball-on-disc tribometer. It was demonstrated that the wear resistance of the alloys had been increased significantly by the titanium-carbide reinforcement and the hot isostatic pressing process had enhanced the wear resistance of the materials.
