Özet
Additive manufacturing (AM) is gaining attention in the industry as it allows the production of material types with desired mechanical properties and parts with complex geometric shapes and is constantly evolving. This manufacturing method can consist of many different manufacturing techniques. In these production techniques, there are many different parameters to produce materials with the desired properties. Depending on the properties of the part we will produce, production can be done at low cost. One of the main reasons for the widespread use of additive manufacturing is that parts with special design can be produced with this method. Laser additive manufacturing, one of the additive manufacturing methods, is the process of joining different metal powders by melting/sintering with the help of laser beams. In this study, samples produced by Direct Metal Laser Sintering (DMLS) technology were taken as ready-made In this study, AlSi10Mg samples were fabricated by DMLS method using fixed fabrication parameters (laser power (w), energy density (j/mm³), layer thickness (mm), process speed (mm/sec)). An experimental study was carried out by surface roughness measurement, surface abrasion (volume loss) calculation and surface hardness measurements. For this purpose, cylindrical specimens of AlSi10Mg alloy were produced using DMLS method at appropriate parameters and different angles (0°, 45° and 90°). Hardward surface hardness measurement with HV 0.1 (100gr. pressure) was performed on these materials, followed by surface roughness measurement and then surface abrasion of the samples at different loads with 320 mesh sandpaper on TURKYUS device and volume losses were measured. These measurement experiments on materials produced in different geometric parameters (production direction) were compared and it was determined which samples and under which load had more wear and new information about AlSi10Mg alloy was provided to the literature.
