Sintering and Characterization of SiC Reinforced Ni Powders in Microwave Furnace
Abstract
SiC reinforced nickel matrix composites,
microwave at different temperatures It is produced by sintering in oven. Nickel
deposition on SiC powders was achieved by using electroless nickel plating
technique. It is sintered at temperatures
between 500°C, 600 °C, 700°C, 800°C and 900°C under Ar atmosphere. XRD, SEM
(Scanning Electron Microscope), pressure test and hardness measurements were
used to characterize the properties of sintered samples in microwave furnace. The
experimental results, maximum compressive strength (σmax) and hardness (HV)
were carried out at 800 °C. Microwave
sintering of Ni-coated SiC powders without electric current can be a promising
technique for producing ceramic-reinforced nickel composites.
