| CuSn10 pre-alloyed bronze with iron and graphite powders were mixed, pressed and sintered for the bronze pad fabrication. The powder mix was pressed under pressure in the range of 100-600 MPa and sintered at temperatures between 780-850°C. The optimum compression was at 500 MPa and the optimal sintering temperatures was 730°C. 2 wt.% of graphite addition was sufficient to adjust the friction and wear properties of produced bronze pad samples. Optical microscope and SEM images showed that a homogenous powder mix was achieved. The produced bronze samples and the commercial ones were compared and beneficial properties of them were determined. The wear behaviours of both the produced friction materials and the commercial pads were examined. The coefficient of friction and wear rates were determined. The sintered bronze samples and the commercial bronze pads have exhibited similar wear behaviour, although the commercial one have contained ceramic particles. |
