Sintering and Mechanical properties of Hydroxyapatite by Spark Plasma Sintering

Abstract

This research focuses on the sintering and its mechanical properties of hydroxyapatites by spark plasma sintering (SPS) process. Sintering conditions are heating rate, sintering temperature, sintering time, sintering pressure, etc. The sintering conditions intricately affect each other. To determine the optimum sintering conditions, many sintered compacts are typically fabricated using all the combinations of sintering conditions. In this research, the optimum sintering conditions of HAp powders were determined by using the methodology of Robust Engineering. The optimum conditions can be determined with fewer compacts without sintering under all combinations of sintering conditions using this methodology. The mechanical properties of HAp sintered compacts were discussed.
