Abstract

<jats:title>Abstract</jats:title><jats:p>Recently, additive manufacturing techniques have begun to be implemented extensively in the production of implants. Selective laser melting (SLM), one of the layered manufacturing methods, is a method that is fre-quently used in implant production. Ti6Al4V alloy is a material of choice for implants due to its low density and high biocompatibility. Recent research, however, has demonstrated that Ti6Al4V alloy emits long-term ions (such as Al and V) that are hazardous to health. Surface modifications, including coating, are therefore required for implants. Selective laser melting (SLM), one of the layered manufacturing methods, is a method that is frequently used in implant production.&amp;#xD;In this study, zinc-supported TiO2 was deposited on a part produced by SLM using the electrodeposition method, which has not been applied before. Thus, Al and V ions that would be released from the Ti6Al4V alloy were prevented. The effects of processing time, amount of TiO2 addition, microstructure of anode materials, and resistance to wear and corrosion were investigated. The coating hardness and thickness increased with increasing processing time and TiO2 concentration. It has been observed that the addition of TiO2 to zinc anode coatings results in an increase in wear and a decrease in corrosion rate. It was noted that the specimens exhibiting the most significant wear also possessed the highest hardness value. The specimens were gene-rated utilizing a graphite anode, underwent a 30-minute processing time, and comprised 10 g/l of TiO2.Keywords: electrodeposition coating; additive manufacturing; Ti6Al4V Grade 5 ELI; TiO2 ceramic; corrosion&amp;#xD;</jats:p>
