This study presents the development of niobium carbide cermets bound to nickel and Ni-12Al (wt%). The use (wt%) Ni aims replace strategic elements such as cobalt (Co) utilized in tungsten carbide-based cermets. Cermets different compositions were processed by conventional powder metallurgy. Microstructural analysis with semi-quantitative chemical EDX, Vickers microhardness density measurement p...

In pelvic fracture operations, bone plate shaping is challenging and the operation time is long. To address this issue, a customized bone plate was designed and produced using selective laser melting (SLM) technology. The key steps of this study included designing the customized bone plate, metal 3D printing, vacuum heat treatment, surface post-processing, operation rehearsal, and clinical appl...
