Relationship between Microstructure and Wear Behaviour in A356 Alloy and A356/Al2O3 and A356/WC Composites After Casting and Hot-Extrusion
The present study, with its practical implications, evaluates the relationship between microstructure and specific wear rate/friction coefficient in A356 alloy and A356/Al2O3 and A356/WC composites after casting and hot-extrusion. The characterization of crystalline phases was carried out using X-ray diffraction, and the microstructure was characterized by scanning electron microscopy. The comprehensive use of rotating (Pin-on-Disk) and linear reciprocating wear testers ensures a thorough understanding of the materials’ specific wear rate and friction coefficient behaviors. The results show a direct relationship between specific wear rate, friction coefficient, microstructure evolution, and hardness in the systems studied after casting and hot extrusion. In addition, the specific wear rate and friction coefficient decrease as the load increases during tests; however, the friction coefficient is more sensitive to hardness values at low loads; at as-cast conditions, this value decreases concerning the reference sample a 13% and 10% for the A356/Al2O3 and A356/WC composites, but at the extruded conditions, increases by 30% and 111%, which is in a direct relationship to values of hardness obtained.
期刊介绍：
Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
