In this study, the sintering of nickel-based colmonoy superalloy powder was investigated using the Spark Plasma Sintering process. The sintering process was performed by a device under a pressure of 40 MPa and 700, 750, 800 and 850 ° C for 5, 10 and 15 minutes. The powder used was first analyzed by XRF and XRD tests. After the process, the effect of temperature and time changes on the porosity and strength of the produced samples was investigated. The porosity of the structure was measured by image processing method and ImageJ software. Optical microscope images showed that the samples were sintered for 5 minutes at temperatures of 700, 750 and 800 ° C had a porous structure with insufficient strength. In the next stage, sintering was performed at 850 ° C for 5, 10 and 15 minutes. The results showed that with increasing sintering time, the porosity of the structure decreased. Shear punch test was used to measure the strength of the samples. The test results showed that with increasing sintering time and temperature, the strength and deformation rate of the samples increased. The lowest porosity was related to the sample that sintered at 850 ° C and a time of 15 minutes with 1.9%, which results in a strength of 266 MPa. The oxidation test results showed that the sample sintered at 850 ° C and 5 minutes time were the most and the sample sintered at the same temperature and time of 10 and 15 minutes after 24 hours, the least weight change.
