Abstract
Abstract Spark Plasma Sintering (SPS) has been recognized, in the recent past, as a very useful method to produce metal matrix composites with enhanced mechanical and wear properties. Obviously, the material’s final properties are strongly related to the reinforcement types and percentages and the particles’ distribution, as well as to the processing parameters employed during synthesis. The present article analyzes the effect of microscopic and nanometric alumina particles, blended to pure aluminum in different combinations, on the final properties of metal matrix composites produced via SPS. A strong variation in the microstructural behavior, mechanical, and wear properties has been observed by varying the nano- to micro-alumina particles’ percentage and the distribution of the ceramic particles blended with aluminum ones.
