Abstract
Within this work, the effect of etching parameters on the surface morphology of Ti6Al4V alloy was investigated. For this purpose, different temperatures, different proportions of HCl-H2SO4 acid mixtures and different etching times were used for the etching process. After etching, XRD analyses, SEM images and surface roughness values of the samples were presented. It was observed that increasing etching temperature facilitated the formation of pore structure on the surface, but after a certain temperature, the increasing temperature started to show negative effects. When all the microstructure images are considered, it is understood that acid concentration and etching time are effective parameters besides temperature difference.

Summary
Due to their superior compatibility with the body, titanium and its alloys are often used in implant materials. The most important factor determining the performance of Ti6Al4V implant material in the body is the surface properties. Modifications of surface topography alterations are made to increase the response of cells to the implant. The speed and quality of osseointegration in titanium implants are related to their surface properties [2]. Various studies have been conducted to improve osseointegration of the implants with different surface modifications. The main objective of implant manufacturers is to improve the surface properties of implants for protein adsorption, cell differentiation, adhesion and osseointegration [3]. Implant surface modifications have been applied to titanium surfaces to increase biomechanical bonding between the implant and bone, to increase adhesion between the implant bone by enlarging the contact surface, and to increase osteoblast activity with faster formation of bone at the interface [9,10,11,12]
