“…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) . The normal load is marked on the X-axis, while the sliding velocity is marked on the Y-axis and the resultant wear rate is plotted on the Z-axis.…”

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 paper deals with improvement of the electron-beam additive forming of metal products using a vertically fed filler wire in vacuum with two electron beams as a heating source. We compared the importance of the power of the heat source required for fusing the layers with each other and the calculated power of the heat source required to melt the filler wire and the surface of the product. Within the experimental conditions of the multilayer electron beam deposition using side wire feeding, the electron beam power of 2.4 kW was required to ensure fusion without the defect formation between the layers during the deposition of Ti-6Al-4V titanium alloy. At the same time, approximate calculations of the minimum power of the heat source required to melt the filler wire and the surface of the product showed a level of 730 W.
