A comprehensive study on surface integrity of nickel-based superalloy Inconel 718 under robotic belt grinding

The components being manufactured in aerospace industry must be capable of being utilized for long periods without failure. Thus, the functional behavior of these machined components is greatly dependent upon their surface integrity. The present work compares the performance of palm oil and synthetic ester on surface integrity when drilling of Inconel 718. The results indicate the substantial benefit of MQL by palm oil on microhardness, surface roughness, surface defects and sub-surface deformation.

Robotic Belt Grinding

Surface corrosion resistance of nickel-based superalloys after grinding is an important consideration to ensure the service performance. In this work, robotic belt grinding is adopted because it offers controllable material processing by dynamically controlling process parameters and tool-workpiece contact state. Surface corrosion behavior of Inconel 718 after robotic belt grinding was investigated by electrochemical testing in 3.5 wt % NaCl solution at room temperature. Specimens were characterized by morphology, surface roughness and residual stress systematically. The potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) analysis indicate the corrosion resistance of the specimen surface improves remarkably with the decrease of abrasive particle size. It can be attributed to the change of surface roughness and residual stress. The energy dispersive X-ray spectroscopy (EDS) indicates that niobium (Nb) is preferentially attacked in the corrosion process. A plausible electrochemical dissolution behavior for Inconel 718 processed by robotic belt grinding is proposed. This study is of significance for achieving desired corrosion property of work surface by optimizing grinding process parameters.

The use of GH4169 nickel-based superalloy for the manufacture of gas turbine engines components for aerospace/energy applications has become a routine exercise. However, components with complex designs specifications might pose manufacturing challenges especially when grinding processes are needed to enable their compliance with tight industrial standards for workpiece surface integrity. Information on grinding processes for such sensitive industrial applications is scarce. The paper reports on the influence of grinding methods/strategies on the quality and integrity of workpiece surfaces obtained after abrasive belt grinding methods on GH4169 nickel-based superalloy. The influences of grinding speed, contact pressure and oscillation frequency on surface roughness were discussed. The performance of the abrasive belt and surface topography were discussed. As a result, the maximum surface roughness of Ra is 0.072μm, and have a good performance of the abrasive belt, it could be concluded that abrasive belt grinding might be considered as a viable process for grinding aero-engine components.
