ZrSiO4 的磨擦穿性质增强了样品被测量,与那些相比,平原,铜基于。为这个目的,密度,坚硬,磨擦系数穿样品的行为被测试。在 sintering 和穿的表面前后的样品的微观结构被扫描电子显微镜学(SEM ) 也调查,并且 wear 类型是坚定的。最佳磨擦穿行为在在最后的样品的 820 ° C .Density 在 500 MPa 和 sintered 压缩的样品被获得与增加在 sintering 以后在 pre-sintering.However 前增强元素(ZrSiO4 ) 的数量减少了,在包括增强元素(ZrSiO4 ) 的样品的密度没有变化。与增加磨擦表面温度,在样品的磨擦系数的减小被观察。然而,在磨擦系数的最高的减小在包含样品的 0,5% 增强的 ZrSiO4.The SEM 图象的同样收到的样品被观察当没有 ZrSiO4 的基于铜的裂缝衬里材料显示出磨料时,显示了那穿行为,增加 ZrSiO4 的数量结果在到粘合剂的磨料的一个变化穿机制。所有样品展出了磨擦穿价值,它在在 SAE-J661 标准显示出的价值以内。与增加增强 ZrSiO4 的数量,穿样品的抵抗被增加。然而,与 5% 和 6% ZrSiO4 增强的样品证明最好结果。
Friction-wear properties of the ZrSiO4 reinforced samples were measured and compared with those of plain bronze based ones. For this purpose, density, hardness, friction coefficient wear behaviour of the samples were tested. Microstructures of samples before and after sintering and worn surfaces were also investigated by scanning electron microscopy (SEM), and the wear types were determined. The optimum friction-wear behaviour was obtained in the sample compacted at 500 MPa and sintered at 820℃. Density of the final samples decreased with increasing the amount of reinforcing elements (ZrSiO4) before pre-sintering. However after sintering, there is no change in density of the samples including reinforcing elements (ZrSiO4). With increasing friction surface temperature, a reduction in the friction coefficient of the samples was observed. However, the highest reductions in the friction coefficients were observed in the as-received samples containing 0. 5% reinforced ZrSiO4. The SEM images of the sample indicated that while bronze-based break lining material without ZrSiO4 showed abrasive wear behaviour, increasing the amount of ZrSiO4 resulted a change in abrasive to adhesive wear mechanism. All samples exhibited friction-wear values, which were within the values shown in SAE-J661 standard. With increasing the amount of reinforcing ZrSiO4, wear resistance of the samples was increased. However samples reinforced with 5% and 6% ZrSiO4 showed the best results.
