Development and selection of an adequate bearing material with distinct characteristics for wear resistant applications is one of the most crucial tasks. Inappropriate selection of material may cause hindrance and result in failure of components during its functioning. To this end, this research focusses on fabrication of bearing materials reinforced with varying weight percentages of industrial waste, i.e. marble dust, and the physical, mechanical and tribological characteristics were determined. The proportions of marble dust were varied from 0 wt. % to 10 wt. % with a gap of 2.5 wt. % and filled in a silicon-bronze alloy. The physical and mechanical properties were realized by the Archimedean principle, micro-hardness tester and Instron 3369 universal testing machine respectively. The tribological properties such as friction and wear behaviour were determined utilizing pin-on-disk tribometer under different condition at normal room temperature. Due to the conflicting nature of desired properties in a bearing material, the Vise Kriterijumska Optimizacija Kompromisno Resenjemeaning under fuzzy environment was applied to rank and select the optimal composite among available alternatives because it can obtain compromise solution considering overall satisfaction and regret of the selection of the wrong provinces. From the analysis of the results, it was found that silicon-bronze-3 marble dust bearing material containing 7.5 wt. % marble dust achieved the best possible set of the properties for wear resistant applications.

轴承用高温真空铸造大理石粉尘增强硅青铜合金材料开发及选材的初步评价

为耐磨应用开发和选择具有独特特性的合适轴承材料是最关键的任务之一。材料选择不当可能会造成障碍并导致组件在其运行过程中出现故障。为此，本研究侧重于用不同重量百分比的工业废物（即大理石粉尘）增强轴承材料的制造，并确定了物理、机械和摩擦学特性。大理石粉尘的比例从 0 wt. % 至 10 wt. %，间隙为 2.5 wt。% 并填充硅青铜合金。物理力学性能分别通过阿基米德原理、显微硬度计和Instron 3369万能试验机实现。摩擦学性能如摩擦和磨损行为是在正常室温下使用不同条件下的销盘式摩擦计测定的。由于轴承材料中所需特性的冲突性质，模糊环境下的 Vise Kriterijumska Optimizacija Kompromisno Resenjemeaning 被应用于对可用替代品中的最佳复合材料进行排序和选择，因为它可以在考虑整体满意度和选择的遗憾的情况下获得折衷解决方案错误的省份。从结果分析中发现，硅-青铜-3 大理石含尘材料含有 7.5 wt. % 的大理石粉尘实现了耐磨应用的最佳性能。由于轴承材料中所需特性的冲突性质，模糊环境下的 Vise Kriterijumska Optimizacija Kompromisno Resenjemeaning 被应用于对可用替代品中的最佳复合材料进行排序和选择，因为它可以在考虑整体满意度和选择的遗憾的情况下获得折衷解决方案错误的省份。从结果分析中发现，硅-青铜-3 大理石含尘材料含有 7.5 wt. % 的大理石粉尘实现了耐磨应用的最佳性能。由于轴承材料中所需特性的冲突性质，模糊环境下的 Vise Kriterijumska Optimizacija Kompromisno Resenjemeaning 被应用于对可用替代品中的最佳复合材料进行排序和选择，因为它可以在考虑整体满意度和选择的遗憾的情况下获得折衷解决方案错误的省份。从结果分析中发现，硅-青铜-3 大理石含尘材料含有 7.5 wt. % 的大理石粉尘实现了耐磨应用的最佳性能。模糊环境下的Vise Kriterijumska Optimizacija Kompromisno Resenjemeaning被应用于对可用备选方案中的最优组合进行排序和选择，因为它可以在考虑总体满意度和选择错误省份的遗憾的情况下获得折衷解决方案。从结果分析中发现，硅-青铜-3 大理石含尘材料含有 7.5 wt. % 的大理石粉尘实现了耐磨应用的最佳性能。模糊环境下的Vise Kriterijumska Optimizacija Kompromisno Resenjemeaning被应用于对可用备选方案中的最优组合进行排序和选择，因为它可以在考虑总体满意度和选择错误省份的遗憾的情况下获得折衷解决方案。从结果分析中发现，硅-青铜-3 大理石含尘材料含有 7.5 wt. % 的大理石粉尘实现了耐磨应用的最佳性能。
