Water-jet guided laser drilling of SiC reinforced aluminium metal matrix composites

Laser drilling of monolithic materials like metals and alloys is a well-established process and used extensively in a wide range of applications in many sectors including aerospace, medical and automotive. However, conventional laser drilling of materials like metal matrix composites is challenging due to the differences in the chemical and physical properties of the hard ceramic reinforcement particles and the soft-metal matrix. The water-jet guided laser process has the potential to machine advanced materials such as an aluminium metal matrix composite reinforced with silicon carbide particles (Al MMC), with exceptional quality. The main objective of this research is to understand the material removal mechanism associated with water-jet guided laser drilling of Al MMCs and compare this with conventional laser drilling of Al MMC. Experimental results showed that the water-jet guided laser process is an excellent technique for drilling holes in composite materials like metal matrix composites. During water-jet guided laser drilling of Al MMC, the material has been removed by cold ablation, without leaving any residual melt layer within the bulk material. Both soft-matrix and hard-particles are removed by the same process of cold ablation, which is completely different to the conventional laser drilling process in which the solid SiC are ejected without melting, along with the molten aluminium.

Abstract: Aluminum based metal matrix composites (AMCs) are very useful and demanded in space and vehicle sector because they carry excellent properties like light weight, ductility, great strength, and toughness apart from this they can be handled by predictable methods. Melt casting and powder metallurgy methods are widely adopted for fabricating the compounds as compared to other technique. Casting methods is used for prepare the complex shapes because powder metallurgy technique is not able to prepare such type of complex shape though it is further cost effective than the melt casting techniques. Casting with stirring has certain advantages over powder metallurgy because it allows for better matrix particle adhesion, easier matrix structure control, low cost, simplicity, and the formation of precise shapes. The Casting process can be utilised with a wide range of materials. Aluminium metal matrix composites, on the other hand, have been found to have superior wear resistance and mechanical qualities. The tribological and mechanical properties of aluminium based alloy matrix composites manufactured using various casting processes are summarised in this review paper. Keywords: Metal Matrix based on aluminium, Manufacture methods, mechanical and tribological characterization.
