“…However, the poor finishability of the β-TNTZ alloy is one of critical barriers that limit the performance quality by attracting bacterial infection [ 17 ] and vulnerability to attract plaques [ 18 ], which entail inflammation around the implant surface [ 19 , 20 , 21 ]. Indeed, a wide range of finishing processes, including grinding [ 22 ], honing [ 23 ], ball burnishing [ 24 ], flexible abrasive tools [ 25 ], etc., have been developed for processing the free-form surfaces of the developed implants. As per [ 26 ], the manual finishing of the implant surfaces is non-effective, imprecise, and takes more time.…”

The present work explores the potential of magneto-rheological fluid assisted abrasive finishing (MRF-AF) for obtaining precise surface topography of an in-house developed β-phase Ti-Nb-Ta-Zr (TNTZ) alloy for orthopedic applications. Investigations have been made to study the influence of the concentration of carbonyl iron particles (CIP), rotational speed (Nt), and working gap (Gp) in response to material removal (MR) and surface roughness (Ra) of the finished sample using a design of experimental technique. Further, the corrosion performance of the finished samples has also been analyzed through simulated body fluid (SBF) testing. It has been found that the selected input process parameters significantly influenced the observed MR and Ra values at 95% confidence level. Apart from this, it has been found that Gp and Nt exhibited the maximum contribution in the optimized values of the MR and Ra, respectively. Further, the corrosion analysis of the finished samples specified that the resistance against corrosion is a direct function of the surface finish. The morphological analysis of the corroded morphologies indicated that the rough sites of the implant surface have provided the nuclei for corrosion mechanics that ultimately resulted in the shredding of the appetite layer. Overall results highlighted that the MRF-AF is a potential technique for obtaining nano-scale finishing of the high-strength β-phase Ti-Nb-Ta-Zr alloy.

The article deals with fragments of technological heredity, which is the basis of a new scientific and practical direction in mechanical engineering technology aimed at improving machine parts' performance by technological methods in manufacturing parts. The purpose is to study thermomechanical phenomena affecting the quality of the surface layer, taking into account the processing of products and genetic heterogeneities formed in previous technological operations, to establish the influence of these inhomogeneities on crack and burn formation based on quantitative analysis of the thermal and stress state, as well as with taking into account the heterogeneity of the material of the products. The problem of determining the stress-strain state of a piecewise homogeneous product material, the upper layer containing thin inclusions and crack-like defects, and the active layer of which is subject to mechanical processing, is considered. It was found that the presence of various defects in the surface layer of the processed products, introduced at the stage of obtaining the workpiece and subsequent types of processing, requires the formulation of fracture mechanics criteria in the study of the causes of crack formation.

The traditional finishing method cannot keep up with recent labor market requirements, solve the problem of increasing production, improve the surface roughness and accuracy of workpiece. While the unconventional magnetic abrasive finishing (MAF) method has shown as a promising technique that can be used to finish complicated surfaces. MAF finishes metals, alloy, ceramic, and other materials that are difficult to finish by other processes. In another word, MAF improves the quality of surfaces with low cost. This paper focuses on optimize and study the effect of inductor and pole geometry (radius of hole, angle of core, angle of pole, radius of pole), on (surface roughness (Ra) and material removal weight (W)) and fined the optimum values that increase the efficiency of MAF method. Taguchi method employed to study the influence of geometry parameters and find the optimum values using orthogonal array L9. The results conclude that the most significant factor that effects change in surface roughness (ΔRa) and material removal weight(ΔW) are radius of the hole (R) and angle of core (α), respectively.
