Optimization on WC-Co formulation using Taguchi method for cutting tool application

This research paper is focusing on selection of WC-Co formulation using Taguchi optimization method based on design factors such as percentage of cobalt, vanadium carbide and PKS activated carbon. The effect of design factors on mechanical properties is analyse based on the orthogonal array set-up using the Taguchi method. WC-Co samples were fabricated using powder metallurgy press and sinter technique. Based on the results obtained, hardness and flexural strength were analysed using means value to identify the optimum WC-Co formulation. For high hardness and flexural strength, WC-8Co-0.3C-0.4VC and WC-6Co-0.4VC found to be the optimized combination of levels of all the three control factors.
