Özet
A novel approach of wear plate fabrication by vertical centrifugal casting was proposed and demonstrated in this paper. Wear plates were reinforced by the addition of M7C3 carbide particles during vertical centrifugal casting. The effect of size and the weight ratio of the carbide particles on wear resistance were investigated. The prepared carbide particles were used as 150-2000 ?m in size and 3-20 g in weight per casting. Spheroidal graphite cast iron has been used as matrix material. During casting, the machine was operated at 250 rpm. The carbide powders have been formed a local coating of 300-1600 µm thickness on the sample tip surfaces. The average thickness of the composite formed on the sample surface was found to be 1000-1200 µm. The elemental distributions were analyzed by EDS. XRD and XPS were used for characterizing the phase structures. The samples were subjected to a "block on ring" abrasive wear test. It has been observed that the abrasion resistance of samples having a powder size of 1000-2000 ?m has the highest abrasion resistance. © 2019 Kauno Technologijos Universitetas. All Rights Reserved.
