PARAMETRIC STUDY IN SURFACE OF INCONEL 718 SURFACE WITH MAGNETIC ABRASIVE FINISHING PROCESS. - Softcover

Inhaltsangabe

Inconel 718 is a nickel based alloy used in high pressure and temperature applications due to its high strength and thermal resistance properties. Machining of Inconel 718 is very difficult due to its toughness characteristics. Surface finishing of Inconel 718 is also a difficult task to deal with. In present work, magnetic abrasive finishing process has been used for external surface finishing of Inconel 718 flat surface (5 mm thick plate). A number of experiments have been designed and conducted to study the effect of three selected process parameters i.e. processing time, pole rotation speed and weight percentage of abrasives on percentage improvement in surface finish. An ANOVA has been used to analyze the experimental results. Experimental results indicate that all the above mentioned parameters have considerable effect on surface finishing of Inconel 718. Effect of different process parameters on surface microstructure of has also been observed using scanning electron microscopy.
