立方氮化硼表面硬化层的制备及性能

用渗硼和新型的等离子体浸没式氮离子注入技术（PⅢ）对Cr12MoV钢进行复合处理，制备出了含有立方氮化硼的表面硬化层。经X光电子能谱和X射线衍射分析发现硬化层中的组织主要是立方氮化硼（c-BN）、六方氮化硼（h-BN）、FeB和Fe2B。在与单独渗硼处理的Cr12MoV钢试样进行对比时，对立方氮化硼表面硬化层进行了维氏显微硬度和滑动摩擦试验。结果表明：硬化层具有高达48GPa的高硬度和优良的摩擦性能。     

RESEARCH ON DESIGN METHOD OF A MULTIPLE DISC WET BRAKE IN LUBRICATED ENVIRONMENT

The rmomechnical phenomena occurring between friction pairs greatly change the distributions oflining pressure and friction surface temperature of a multiple disc wet brake. It has become one of the maincauses of brake failure. In order to understand these thermomechanical phenomena, several design and mate-rial factors tha have great influence on thermomechanical phenomena, such as heat transfer coefficient, fric-tion factor, sliding velocity initial lining pressure and so on, are analyzed. An isothermal design method isproposed for designing a multiple disc wet brake.     

Influence of External Voltage on the Tribological Behavior of Brass／Silicon Nitride Rubbing Couple

Tribological behaviors of the brassl silicon nitride rubbing couple under external voltages were investigated by a self-made friction tester.Three different aqueous solutions were used to find the optimum lubricant that can support a rapid voltage-controlled friction phenomenon Experimental results show that.for all of the solutions,friction coefficients in the presence of an external voltage higher that 6V DC were approximately 2 times higher that those in the absence of an external voltage.the response time of friction force to a step incrensed under external voltage could be as short as 0.5 s in these solutions,while 1.58s was needed for the recovery process of friction the main factors predlominating the step response of friction discussed.     

浅谈设计多绳摩擦式副立井提升机房

随着煤矿生产能力的提高，副立井提升机房的设计也发生相应变化。以往的单一的提升方式已不能满足现代企业生产的需要，并逐步发展到多轮、多绳的提升方式。由于煤炭行业无提升机房土建设计的标准，有关提升机基础的技术参数只能参考现有其他规范，某些参数取得过于保守，且无根据。提升机基础的配筋应该引起设计人员的重视，基本概念必须明确。论文对副立井提升机房厂房主体及提升机基础的设计进行了简要阐述。     

气封解决了致命的摩擦问题——针对冷凝式汽轮机的气体润滑机械式密封

高能电子辐照对二硫化钼填充酚酞聚芳醚酮复合材料摩擦磨损性能影响的研究

石墨、二硫化钼、聚四氟乙烯是常用的固体润滑剂，但石墨和二硫化钼并不能在任何情况下都降低材料的摩擦磨损；聚四氟乙烯一般仅能降低材料的摩擦系数，而对磨损的降低不显著。填料对复合材料的影响很复杂，因此必须在实际的摩擦学系统中来评价填料的作用。
