Effect of MgFeSi Inoculant on Properties of Cast 6061 Al Alloy for Brake Master Piston Application
The influence of varying amount of MgFeSi inoculant on properties of cast 6061 Al alloy for brake master piston application has been studied and reported in this paper. Cast samples were produced at three pouring temperatures (700, 750, and 800°C) with MgFeSi varied from 1 to 3%. Wear resistance tests were performed on cast alloy in brake oil. Wear resistance tests results were validated by nondestructive examinations using photomicroscopy, SEM, EDX, and XRD data. The addition of MgFeSi influenced both the mechanical (hardness, strength, and wear resistance) and metallurgical properties (microstructures) of the cast alloy. Al grains were more refined and yielded good strength properties. Inoculating the melt with MgFeSi forms insoluble compound particles and is responsible for grain refinement. The increased amount of MgFeSi from 1 to 3% improved the wear resistance of the cast piston under lubricating condition using brake oil.
