Effect of hybrid modification by ceramic layer formation in MAO process and laser remelting on the structure of titanium bio-alloy Ti13Nb13Zr
Abstract
To improve the biological properties of titanium alloy Ti13Nb13Zr, hybrid modifications involving micro-arc oxidation (MAO) and Nd: YAG laser remelting were carried out in two combinations. The first consisted of laser modification before the production of the ceramic layer by the micro-arc oxidation process, and the second combination involved Nd: YAG laser modification after the MAO process. The creation of developed surface morphologies on titanium alloys used in implant manufacturing is currently a widely discussed trend. The modifications used by the authors offer the possibility of obtaining a porous, wettable surface with altered nanohardness. To investigate the structural properties of the obtained hybrid Nd: YAG-MAO and MAO-laser Nd: YAG modifications, the structure roughness tests were performed with a suitable apparatus and atomic force microscope (AFM) and available software. The surface wettability was evaluated and the surface of the modified Ti13Nb13Zr alloy was subjected to evaluation using a scanning electron microscope (SEM), and an optical microscope. Using available software, chemical composition analysis, porosity analysis, and, adhesion analysis were performed. Based on the tests carried out, the possibility of carrying out hybrid modification in various combinations was demonstrated. The presence of Na+ and Ca2+ ions was demonstrated for samples in the combination of laser modification and MAO modification, which is important for biomedical reasons. Each modification allowed changing of the nanohardness, wettability, and roughness in the direction expected, required from biomedical materials. This paper presents an innovative approach to the use of two modifications one using the effect of heat on the matrix and the other focused on the formation of a ceramic coating. Currently, hybrid modifications are desirable in that they allow them to interact positively with each other.
