Investigation of tribological behavior and corrosion resistance in different environmental conditions of metal matrix composite samples obtained by impregnating 2D MXene doped epoxy on porous Ti6Al4V matrices produced by using the Selective Laser Melting method

With today's changing and developing technologies and the increasing population density of our planet, the need for energy is increasing. In addition to the search for new types of energy resources, the efficient use of existing energy resources has become the common goal of all scientists. Therefore, in the industrial sector, there is a trend towards easy-to-produce and long-lasting machine elements. In order to save energy, in addition to the easy production of machine elements, it is necessary to reduce the forces (friction, mass inertia, etc.) working in the opposite direction to the drive motor where they will be used. Especially when the machine elements used in the automotive and aviation industries work under extreme conditions (vacuum, low temperature, corrosive, etc.), these parts are expected to be light and have wear and corrosion resistance. In this way, the service life of the machine elements is long and the fuel efficiency of the vehicles is high. For this purpose in this thesis, a new generation metal matrix composite (MMC) material was designed and produced by combining the unique properties of 2D MXene materials and the advantages of metal additive manufacturing with no geometric design limits. The textured metal matrix of this MMC was produced with Ti6Al4V material by Selective Laser Melting (SLM) method and the reinforcement element that increases wear and corrosion resistance was produced with 2D MXene added to epoxy resin (ER). Thus, wear tests under different environmental conditions and corrosion tests in corrosive environments were applied to MMCs whose mass was reduced by 20%. Compared to samples produced entirely from Ti6Al4V, thanks to ER and MXene reinforcement, both friction forces and wear rates were reduced in all wear environments. Corrosion resistance was significantly higher than the untextured samples, again thanks to the addition of insulating ER.
