A Description of Surfaces Created on the Hybrid MMC by the AWJ Cutting Technology

Metal Matrix Composites (MMCs) are one of the appropriate choice of materials in today‘s manufacturing industries for various engineering applications. However, machining of such hard materials is still a challenging task due to high tool wear in conventional methods. Non-conventional method such as abrasive water-jet cutting is one of the preferred choice for processing of these materials. In this work, the study of machined surfaces produced by Abrasive Water-Jet (AWJ) cutting on hybrid MMC A359/Al2O3/B4Cis discussed. Three different samples of producing hybrid MMC were taken for the study at different proportion (2%, 3% and 4%) of each reinforcement. The study includes the comparison of AWJ created surfaces for each sample in terms of microstructural examination and surface characteristics. It also focused on 2D and 3D detailing of the surfaces to discuss the major points of topographical aspects. The results reveal the successful cutting of hybrid MMCs.
