Research project: Surface texturing of a lightweight aluminium-silicon alloy

Currently Active: 
Yes

The project explores the potential of using electro-chemical jet machining to surface texture light-weight hyper-eutectic aluminium alloys for automotive applications

Hyper-eutectic aluminium-silicon alloys are difficult to surface texture using conventional laser techniques due to the unique surface topography they require to function correctly. Electro-chemical jet machining provides an alternative approach to introduce surface textures by dissolving material using electro-chemistry. This allows Al-Si alloys to be textured, improving the friction behaviour when sliding against piston ring materials.
