Abstract
AbstractIn this study, micro-cracks analysis has been carried out on pure bio-implant titanium material in terms of length and number of micro-cracks after wire electric discharge machining (WEDM). The effect of WEDM parameters on micro-cracks propagation was subjected to metallurgical characterization through a scanning electron microscope and EDX. The experimental results show that the quantitative analysis of micro-cracks plays a significant role to deteriorate the morphology of machined surfaces, resulting in deeper, bigger globules of debris and micro-cracks. X-ray diffraction was used to study the phase transformations that occurred in the formation of substances like titanium dioxide (rutile), Ilmenite, titanium carbides (TiC), and copper titanium dioxide. To reduce the micro-cracks, an optimal parametric setting was obtained through the desirability function. A BBD approach was used to develop the experimental design. The effect of WEDM parameters: POT, PC, and SGV for micro-cracks were predominantly affected.KeywordsWEDMMicro-cracksBio-implantANOVAXRDEDX
