Effects of Abrasion Rate and Thermal Conductivity on Copper-Chill Plate/DCT-Chill Plate Amalgamated with Al-Mg/Sic Composites

Abstract

Engineers today face a significant problem in choosing the best material and production process for an application because of the huge variety of materials available. In this study, silicon carbide reinforcement was supplemented with various compositions, ranging from 3 to 12%wt. The sand-cast Al6061alloy with adding Deep-Cryo Treatment (DCT) of a copper chill plate d to other composites, which exhibits high thermal stability and can withstand elevated temperatures without crucial degradation, making SiC reinforced suitable for applications requiring thermal resistance, such as aerospace components, automotive parts, and high-temperature machinery. via the stirrup-die casting process. To prevent any leakage of the molten metal from the joints, the edges were sealed with DYCOTE 140 ceramic paste. The results show that incorporated with DCT-Cu chill plates exhibits finer grain structure bonding between matrix and reinforcement. The highest wear rate and coefficient friction was noted at a testing temperature of 150^oC for all chilling plates. Furthermore, the DCT-3%Cu chill plate enhance better wear and friction resistance compared to other compositions. The SiC exhibits high thermal stability and can withstand elevated temperatures without crucial degradation. This property makes SiC-reinforced suitable for scope requiring thermal resistance, such as aerospace components, automotive parts, and high-temperature machinery.
