Özet

Additive manufacturing (AM) is a manufacturing method used to produce high-performance components for automotive, aerospace, and medical applications. Selective laser melting (SLM), one of these methods, has been used to produce aluminum alloy components in recent years. However, the properties of aluminum alloys produced by this method need to be improved. In this study, rotary bending fatigue tests were performed on AlSi10Mg alloy produced by the SLM method and electroplated with nickel. In addition, the surface properties, fracture surfaces, and fatigue life of the nickel electroplated and non-plated specimens were investigated. While most surface coating treatments applied to conventional materials reduce fatigue strength, nickel plating positively affects AM-produced aluminum alloys. Thus, the results are promising for the use of nickel plating in AM fabricated machine parts. Furthermore, nickel coating, which reduces the surface defects of additive manufacturing, is the reason for the increase in fatigue strength, and the results confirmed this.
