Abstract
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 μm 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 μm has the highest abrasion resistance. DOI: http://dx.doi.org/10.5755/j01.mech.24.6.22473

Summary
Metal arc welding, sintered carbide tiles bonding, gas tungsten arc (GTA), plasma transferred arc (PTA), thermal spraying, laser cladding modification processes have been widely used in the composite wear plate production of various types of machine parts and tools. Pulsed detonation spray technique was used for deposition of Cr3C2-NiCr, Stellite-21 and WC-Co-Cr coating powders on high tensile steel Wear properties of these coatings were investigated via the pinon-disc mechanism under dry conditions at ambient temperature in accordance with ASTM G-99 standard [15]. Due to the centrifugal force and relatively high density of WCP, particles in the Fe–C melt moved towards the outer region, leading to the formation of a surface composite ring part This method was used to fabricate SiC particles-reinforced Al alloy-based composite pistons and here, only a brief overview is given [19-21]. The fabrication approach proposed in this study is based on the vertical centrifugal casting where the reinforcement is placed directly over the predetermined locations in the casting mold
