The investigation of traditionally and waste reinforced metalic matrix composites wear behaviour

In this study, a new cheap and easily reachable support material definition aimed alternatively to ceramic with carbide and oxide which is using as support material in particle supported hybrid composite production. Therefore the availability of the wastes which comes up burning of the solid fuel commonly used in our country especially by pulverizing researched. Two stage process molding with agitated is used for hybrid composite production. In this process the aliminum alloy (Al 6061) which will be used as matrix melted in graphite basket in owen with electrically resisted on 700°C, after that coal dross which is used as support element with 45 µm piece size, 22-59 µm alüminyum oksit (Al2O3) and 22-59 µm silisyum karbür (SiC) dusts added by decreasing the heat to 600°C. After mixed by hand of the mixture in shape of slurry, the heat increased to 800°C (super heating) and mechanically mixed in speed of 450 rpm on this heat. The cylindirical samples with length of 300 mm and with diameter of 30 mm producted by pouring the mixture to a metalic cast which is heated to 250°C already. Producted cylindirical samples is cutted by sensitive cutter, the surface is prepared by automatic surface preparetor for micro structure investigation. The porozite quantity of the producted samples determined by Archimed principle, Brinell hardness measurement method used for hardness measurement. Wear experiments did by Pin_on Disk device with the application of constant slip distance, on constant rotation speed with load values of 1N, 3N and 5N. The porozite quantity of composites supported by coal dross is higher than the porozite quantity of compozites supported by SiC ve Al2O3 compared by porozite quantity of uniqe compozites. The increasement on the value of the hardness of the composites in which the coal dross is used as support element is almost equal to the composites wich is produced by traditional support element when the hardness value of produced uniqe composites compared. The loss of the mass has decreased by increasing weight proportionally of the support added to the matrix, the loss of the mass has increased by increasing the applied load value, considering the quantity of the mass loss obtained from wear experiments of produced composites. The coal dross determined as a support material which can be used increasing strength of composite production when the affect of coal dross to the wear evaluated. The availabilty of using coal dross as a support material which is improving the mechanical features of the composite putted forth as a result. Key Words: Composite materials, materials with metalic matrix, alluminium alloy, waste material, wear behavior.
