摘要

Rene 41 alloy is now widely employed in various applications, such as constructions, due to its corrosion resistance and outstanding strength-to-weight ratio. However, due to the decreased density of the Rene 41 alloy, it was unable to sustain greater pressures and stresses in some circumstances. When reinforced materials are added to Rene 41 alloy, it becomes harder than pure alloy. Using the casting method, zirconium oxide particles were combined with Rene 41 alloy at a weight% of 3. Rene 41 alloy - Z2O2 composites were manufactured using the EDM machining technique with current, pulse on time and voltage as input variables. Surface finish and substance removal rate are the results. When compared to other traditional machining methods, the reason for using EDM is to reduce surface roughness and increase material removal rate. The experimental design for this study was structured using the L9 orthogonal array. An AFM and SEM examination was carried out specifically to evaluate the surface parameters of the Rene alloy. The pit and valley surface was observed in the machining surface and the variation in input current and voltage showed noticeable change in the surface roughness and metal removal rate.
