Electrical Sweater Processing (ECI) is an unusual manufacturing method preferred especially in the processing of very hard and complex shaped materials. The processing method with a powder-added electrical welder (TKEKI) is aimed at improving the processing performance with the powder particles involved in the dielectric fluid. For this purpose, many powder additives such as silicon carbon (SiC), copper (Cu), aluminium (Al), iron (Fe) and carbon (C) are used. Hydroxiapatitis (HA) is a bioyum ceramic that is commonly used as a filling material in the bones or to support implants. In addition, titanium (Ti) and titanium alloys are also often preferred in medical applications due to their mechanical properties and corrosion resistance. In this study, the surface characteristics of the Ti-6Al-4V alloy processed with the method of micronized HA powder contributions and the penetration of the powder contributions to the surface during processing were studied. The samples are processed by applying 4 different flow levels and 10 different hit times for each flow level. The processed samples were studied with the scaned electron microscope (SEM), the energy distribution spectrometer (EDS), the X-work breakdown diffractometer (XRD) and the optical microscope. On the surface have been observed rich formations in the direction of HA and the parameters in which these formations are observed have been identified. According to this, the best inflation was observed at 22 A shock streams and 100 μs and 800 μs shock times. Functional surfaces rich in HA are required for medical applications. It is also an innovative approach to obtaining these surfaces by the TEKKI method.
