Abstract

In many industrial applications, hardness and wear come to the fore, especially in materials in contact with each other. It is almost impossible to completely prevent abrasion loss in materials in contact with each other. However, it may be preferable to minimize this rate with various methods or to ensure the abrasion of the material with lower economic value. New and up-to-date materials are needed to minimize wear loss, which is one of the most important mechanisms in engineering applications. It is important to use engineering materials with high friction resistance, especially in places where there is friction. In this study, Al2024 was used as matrix material. A mixture of 50% by weight of Magnesium oxide (MgO) with an average diameter of <40 nm and a 50% multi-walled carbon nanotube (MWCNT) 1.5 µm in length and 9.5 nm in diameter were used as reinforcement. It is produced by composite mixing casting method. Mechanical properties, hardness analysis and abrasive wear behavior of composites have been investigated at different sliding distances (250m-500m-1000m) under 2N and 5N loads.
