are similar, but whereas the friction continues to rise smoothly to a steady state value for 310 steel, the formation of α'-martensite in 304 steel gives a lower average value of friction coefficient with large fluctuations.

【期刊论文】Wear status and researches in tribology in coat mines of China
杨志伊, Z Y YANG
,-0001,():
-1年11月30日
The wear atatue of the mining industry in China is reported. Some researches and applications in tribology in coal mines of China are given. The outhor visited more than 10 collieries to investigate wear losses. We found that in a certain mining area approximately 0.2 Chinese Yuan per ton coal output were spent entirely on consumed parts and about 2 billion or more Chinese Yuan lost per year in coal mines of China due to wearing. The scope of Introduced research includes friction, lubrication, wear research, new technology transfer, wear condition montoring, evaluation of materials, and surface coatings in coal mining industry. Our institute's works are also reperted.

本文提出了利用KTP型旋转式铁谱仪提取机械设备工况特征参量的方法。给出了AM-500型采煤机的液压传动系统和齿轮传动系统的失效判据。突破了传统定性铁谱中单颗粒磨屑的讨论,把机械的工况与磨屑的各种类型和尺寸的总体情况联系起来。
