Abstract

This study delves into the necessity of surface treatment for pure nickel, with a primary focus on applying abrasive jet machining (AJM) in conjunction with a microcontact wear model to investigate the contact interface mechanisms involved in AJM. Experimental findings indicate that SiC particles primarily employ a cutting mechanism to remove asperity peaks on the workpiece surface. While this effectively removes these peaks, it may induce phenomena reminiscent of peen hardening and embedded hardening. Conversely, Al2O3 particles predominantly engage in a rolling extrusion mechanism, leading to noticeable hardening effects akin to peen hardening. The study utilizing microcontact theory derived a 90° erosion wear formula. The study demonstrates that SiC particles outperform Al2O3 particles. SiC particles significantly increase the curvature radius of surface peaks (ρ) and the real contact area (At) during equivalent grinding durations, substantially enhancing workpiece surface quality and service life. Furthermore, post-grinding, an expansion in the elastic deformation region at the particle-workpiece interface, attributed to workpiece surface hardening, mitigates wear, and stabilizes surface roughness. This comprehensive research thoroughly assesses the interfacial effects of different abrasives and grinding parameters, providing valuable insights for related fields.
