In the first stage of the study, the matrix phases were determined using light microscope and scanning electron microscope examinations. The hardness values of the matrices were measured and variation of hardness as a function of dendrite morphology was evaluated. In the second stage, wear tests were carried out using "ball-on-disc" type tribometer. In the wear test, load, total distance and rotating speed were selected as 10 N, 250 m and 100 rpm, respectively. The results were evaluated using the friction coefficient-distance diagram and loss in weight. All worn surfaces were examined by light and scanning electron microscopes and wear characteristics of bronze materials were discussed as a function of dendrite morphology and abrasive layers formed on the worn surface. It was concluded that (i) CuSn10 material produced by sand mold casting technique had a finer dendritic structure and higher hardness than the material produced by investment casting technique, due to rapid cooling, (ii) after the wear test, wear loss of CuSn10 alloy produced by sand mold casting technique was lower due to its higher hardness, (iii) the mean friction coefficient of CuSn10 produced by investment technique was lower since higher content of abrasive layers were formed on its worn surfaces.eninfo:eu-repo/semantics/closedAccessCuSn10 alloyDendrite morphologyMicrostructureWearAbrasivesBronzeFrictionHardnessInvestment castingInvestmentsMicrostructureMorphologySafety engineeringScanning electron microscopyWear of materialsBronze materialCasting techniquesDendrite morphologyDendritic structuresFriction coefficientsHardness valuesSand mold castingWear characteristicsCastingConference Object116N/A108
