The paper examines the abrasive wear rate of samples produced by vacuum impregnation of ultrafine diamond (ASM 1/0) and molybdenum powders with tin bronze. The tests were performed using a SiC-based abrasive wheel in the presence of cooling water. The introduction of and increase in the ultrafine diamond powder in the samples substantially decrease their wear rate (by a factor of 78). The hardness of the samples first increases when diamond powder content rises to 5 wt.% and then decreases when ASM 1/0 content further rises to 11 wt.% because of small porosity that appears in the samples. The use of a bronze matrix containing more than 15 wt.% Sn does not decrease the wear rate of the test samples and, hence, of the associated diamond tools, in spite of increase in their hardness.

超细金刚石和钼粉增强金刚石管钻青铜基样品的耐磨性

该论文研究了用锡青铜真空浸渍超细金刚石 (ASM 1/0) 和钼粉生产的样品的磨料磨损率。测试是在冷却水存在下使用 SiC 基砂轮进行的。样品中超细金刚石粉末的引入和增加显着降低了它们的磨损率（降低了 78 倍）。当金刚石粉含量增加到 5 wt.% 时，样品的硬度首先增加，然后当 ASM 1/0 含量进一步增加到 11 wt.% 时，由于样品中出现的小孔隙率，硬度下降。使用含有超过 15%重量 Sn 的青铜基体不会降低测试样品的磨损率，因此不会降低相关金刚石工具的磨损率，尽管它们的硬度增加了。
