“…In order to classify the different wear modes for this study Fuzzy C-means Algorithm is adopted. The wear modes are categorized as mild wear, severe wear and ultra severe wear (28) . The wear mechanisms map of Ti-6Al-4V was constructed using the Probabilistic Neural Network tool in MATLAB software based on the following procedure (29) .…”

Objectives: To investigate the Micro Hardness, Micro structures and wear characteristics of the TPMS (Triply Periodic Minimal Surface) Gyroid structures with optimized porosity percentage for Bio medical application. Methods: Micro Hardness tester is used to find the micro hardness of the as cast Ti-6AL-4V and Gyroid Ti-6Al-4V Sample. Wear tests using pin-on-disc tribometer was used to assess the Gyroid Ti-6Al-4V wear samples for various loads and sliding velocity. The wear test parameters were test as load of 10, 30 & 50 N, with the sliding velocity of 0.5, 1.0 7 1.5 m/s. Atomic force microscope has been used for finding the surface roughness of the as cast and Gyroid Ti-6Al-4V samples before and after wear test. Findings: According to the test results. It is found that Gyroid Ti-6Al-4V samples posses more wear resistance than as cast Ti-6Al-4V. The micro hardness test results depicted clearly that, the Gyroid Ti-6Al-4V alloy posses' micro hardness of 408 HV in comparison with as cast Ti-6Al-4V alloys' hardness of 358 HV. The morphological characteristics of the worn-out samples were investigated using scanning electron microscope. At higher sliding conditions occurrence of large friction events lead to higher wear rates and the periodic localised fracture of transfer layer. At low sliding conditions, the Gyroid Ti-6Al-4V samples experienced ploughing, peeling off, plastic deformation types of wear mechanism. Novelty: The wear modes were categorised by the Fuzzy C-means algorithm, and a novel PNN tool in MATLAB created a wear map mechanism suitable for the Gyroid Ti alloy. The research conducted in this paper demonstrates a novel methodology for investigating wear mapping using a Probabilistic Neural Network on wear samples with a Gyroid lattice structure.

“…The surface properties of magnesium implants may deteriorate over time due to wear, potentially impacting their biocompatibility and mechanical stability. Surface modifications, coatings, and treatments must be designed to withstand the dynamic and challenging conditions within the human body, ensuring that the wear resistance of magnesium implants is maintained over the course of their intended service life [167]. Magnesium implants, especially those used in load-bearing joints, are subjected to complex loading conditions in the human body.…”

Magnesium has been a focal point of significant exploration in the biomedical engineering domain for many years due to its exceptional attributes, encompassing impressive specific strength, low density, excellent damping abilities, biodegradability, and the sought-after quality of biocompatibility. The primary drawback associated with magnesium-based implants is their susceptibility to corrosion and wear in physiological environments, which represents a significant limitation. Research findings have established that plasma electrolytic oxidation (PEO) induces substantial modifications in the surface characteristics and corrosion behavior of magnesium and its alloy counterparts. By subjecting the surface to high voltages, a porous ceramic coating is formed, resulting in not only altered surface properties and corrosion resistance, but also enhanced wear resistance. However, a drawback of the PEO process is that excessive pore formation and porosity within the shell could potentially undermine the coating’s corrosion and wear resistances. Altering the electrolyte conditions by introducing micro- and nano-particles can serve as a valuable approach to decrease coating porosity and enhance their ultimate characteristics. This paper evaluates the particle adhesion, composition, corrosion, and wear performances of particle-incorporated coatings applied to magnesium alloys through the PEO method.

“…The Special Issue is composed of six full papers concerning plastic deformation processes and their applications. Four out of them are dedicated to burnishing, an advanced finishing operation widely used in various industries [2][3][4]. Burnishing is a plastic deformation process, in which a workpiece surface improves due to sliding contact with a tool called a burnisher.…”
