Özet

PURPOSE: This study aims to investigate the production of composite materials containing Al!Ti particles by centrifugal casting method for ship machinery parts. METHOD: Three different matrix composites reinforced with Al3Ti were produced as Al!Ti /Al, Al!Ti /Al-Cu and Al!Ti/Al-Si. Al!Ti particles were formed spontaneously by the in-situ technique. The prepared semi-solid mixtures were solidified under a centrifugal force for functional grading. Optical microscope, XRD (x-ray diffraction model), scanning electron microscope (SEM) and Brinell Hardness (BHN) were used to determine the properties of the composites produced. FINDINGS: Functionally graded Al!Ti reinforced pure Al, Al-Cu and Al-Si matrix composites were produced successfully by centrifugal casting method. CONCLUSION: It was observed that Al!Ti particles were graded with the effect of centrifugal force from the center outward, and it was determined that the hardness and wear resistance increased with increasing Al3Ti particles inside matrix.
