The present study investigated a hybrid electrical discharge machining (h-EDM) process for producing functionally graded titanium surface. Herein, a stream of hydroxyapatite/titanium oxide abrasive slurry jet has been supplied, through a specially designed tool, to the ionized zone created by the EDM process, and the abrasive particles were finally directed towards the melted region of titanium through ultrasonically produced kinetic energy. The finally produced functionally graded surfaces have been characterized through microscopic analysis to assess the efficacy of the as-produced surfaces. The results highlighted that the abrasive particles have been successfully embedded into the surfaces. The proposed hybrid technology could be used for various engineering applications, including automotive and biomedical sectors.

本研究研究了一种用于生产功能梯度钛表面的混合放电加工（h-EDM）工艺。在此，通过特殊设计的工具将羟基磷灰石/氧化钛磨料浆射流提供给由EDM工艺产生的离子化区域，最终通过超声产生的动能将磨料颗粒引向钛的熔融区域。最终生产的功能渐变表面已通过显微镜分析进行了表征，以评估所生产表面的功效。结果表明，磨料颗粒已成功嵌入表面。提出的混合技术可用于各种工程应用，包括汽车和生物医学领域。
