Tantalum Carbide (TaC) reinforcement was made to lamellar graphite (gray) cast irons that were produced in the physical conditions of a foundry at ratios 0%, 0.025%, 0.155%, and 0.285%. Samples complying with standards prepared using TaC-reinforced iron alloys produced, Brinell hardness tests, compressive strength microstructural analyses conducted. According test results, highest average value...

Experiments are described towards optimizing tantalum silicide (TaSi 2 ) interconnect metal film sputter-deposition and annealing in a manner compatible with the NASA Glenn two-layer silicon carbide (SiC) JFET-R IC process flow. Films deposited on 100 mm diameter wafers were investigated over range of thickness, sputter deposition, post-deposition anneal conditions. An optimized that achieved T...

Porous tantalum has been reported to be a promising material for use in bone tissue engineering. In the present study, the biocompatibility and osteogenic properties of porous tantalum were studied in vitro and in vivo. The morphology of porous tantalum was observed using scanning electron microscopy (SEM). Osteoblasts were cultured with porous tantalum, and cell morphology, adhesion and prolif...

CHARACTERIZATION AND CORROSION OF BCC-TANTALUM COATING DEPOSITED ON ALUMINUM AND STEEL SUBSTRATE BY DC MAGNETRON SPUTTERING by Chirag Joshi Tantalum is one of the most versatile highly refractory corrosion-resistant metals. Tantalum coating can be used as an effective corrosion barrier if it is continuous, free from defects and it adheres well to the substrate. A DC magnetron sputtering techniq...
