Abstract
Tetragonal zirconia polycrystal-alumina (Z-A) composite behaves differently from other ceramics when stressed; it clogs the crack tip and eventually maintains its mechanical robustness. This promising characteristic of Z-A is considered for any load-bearing application where structural strength is needed, especially in the healthcare sector. The present study delineates the fabrication of a novel 2.5D squircle structure intended for bone scaffolding by fiber laser step-down milling (FLSDM) approach on Z-A composite. This article asserts experimental inquisitions to scrutinize the FLSDM process against the ablation characteristics, dimensional veracity, mechanical property, and quality of the treated surface, followed by ceramography analysis (SEM, EDS, XRD, and FTIR). In continuation to that, desirability-based multi-response optimization using the computational PSO-algorithm (MRPSO) was employed to acquire the desired values of FLSDM responses. The current FLSDM process exudes its propriety that can be a choice for the convertible terrain of the Z-A surface to attain the necessitates of scaffolds.
