Biocompatibility is usually observed as the absence of communication of a material with living tissue. Commercially pure titanium grade-2 has become the preferred biocompatible material for various devices mainly used in orthopedic and dental implants and it is also used in aviation and aircraft. Commercially pure titanium has good ductility, higher stiffness, and fatigue resistance. The novelty of the present research work was focused on studying the effect of wire electric discharge matching factors on surface roughness, material removal rate, crack density, and white layer thickness. After machining, the wire electro-discharge machined surface was analyzed through a scanning electron microscope. Further energy dispersive analysis and X-ray diffraction spectroscopy techniques were applied to investigate the material migration on a work surface and brass wire. Each output response has been modeled through analysis of variance to analyze the adequacy. It was observed that pulse on time, pulse off time, peak current, and spark gap voltage are the most significant factors. These factors have been significantly deteriorating the microstructure of machined samples remarkably deeper, leading to wider craters, globules of debris, and micro-cracks. A white layer thickness was also observed in a discontinuous and non-uniform pattern at the cross-section of the machined sample due to rapid heating and quenching phenomena in the wire electric discharge matching process. A multi-objective optimization “desirability” function was applied to obtain the optimal solutions by numerical and graphical methods. In essence, the wire electric discharge matching is a non-traditional process to achieve the accuracy of biocompatibility parts of commercially pure titanium and also finds the improvement in surface morphology.

生物相容性通常被观察为材料与活组织之间没有交流。商业纯钛 2 级已成为主要用于骨科和牙科植入物的各种设备的首选生物相容性材料，也用于航空和飞机。商用纯钛具有良好的延展性、更高的刚度和抗疲劳性。本研究工作的新颖之处在于研究线材放电匹配因素对表面粗糙度、材料去除率、裂纹密度和白层厚度的影响。加工后，通过扫描电子显微镜分析线材放电加工表面。进一步的能量色散分析和 X 射线衍射光谱技术被应用于研究工作表面和黄铜线上的材料迁移。每个输出响应都通过方差分析建模，以分析充分性。据观察，脉冲开启时间、脉冲关闭时间、峰值电流和火花隙电压是最重要的因素。这些因素使加工样品的微观结构显着恶化，显着更深，导致更宽的陨石坑、碎片球和微裂纹。由于线放电匹配过程中的快速加热和淬火现象，在加工样品的横截面处也观察到白色层厚度在不连续且不均匀的图案中。应用多目标优化“意愿”函数，通过数值和图形方法获得最优解。从本质上讲，线材放电匹配是实现商业纯钛生物相容性零件精度的非传统工艺，同时也发现了表面形貌的改进。
