This study examines the surface texture, wear, and corrosion properties of Inconel-800, machining with electric discharge machining (EDM) using boron carbide as a powder additive. Due to Inconel-800’s unusual qualities, it is frequently utilized in a variety of sectors, particularly as a material that can tolerate high temperatures. However, standard methods of machining this material are quite challenging. Using a hybrid technique, the insulating strength of the oil is broken by mixing metal powder in the EDM oil; this technique is commonly known as powder mixed electrical discharge machining (PMEDM). The principal prospective structural material for high-temperature gas-cooled reactors (HTGRs) is Incoloy 800HT. The presence of impurities in the coolant, such as H2O and CH4, may cause corrosion processes that impact tribological behavior. All tests were conducted using a single graphite electrode, and inputs that varied during the research were current, pulse-on-time, and pulse-off-time. Every experiment was conducted twice to avoid error. After machining the surface texture of the specimen, wear and corrosion properties were examined. In comparison to outcomes obtained without using powder additives in EDM oil, the findings demonstrated that the addition of boron carbide powder significantly enhanced the response characteristics, particularly improving the machining properties. Together with the confirmation tests, the findings have been examined both with and without powder mixed dielectric. An energy-dispersive spectrograph (EDS) and scanning electron microscope (SEM) have also been used to analyze the specimen’s surface properties.
