Thermal Debinding and Sintering of water atomised SS316L Metal Injection Moulding Process

Abstract

Thermal debinding of SS316L metal injection moulding samples was done with temperatures of 400°C, 500°C and 600°C was done. Weight loss, density and shrinkage values of the brown part being analysed. X-ray diffraction (XRD) and scanning electron microscopy (SEM)/electron dispersive spectroscopy (EDS) were used to monitor the carburization and oxidation of the thermal debound samples. It is found that, samples under thermal debound temperature of 400°C was less oxidation and carburising as compare to other temperature. Weight loss also indicates higher in percentage although the percentage shrinkage is less. XRD pattern also indicates minor affected in peaks changes as compare to other temperature. Sintering of the thermal debound samples of 400°C temperature shows good microstructure formation and mechanical properties.
