磁记录非牛顿液膜润滑仿真

随着记录密度的不断提高，头盘浮动间隙不断减小。目前近场光、磁混合记录已经在研究10nm以下的浮动系统。由于浮动间隙已远小于空气分子平均自由程(室温下约65nm)而有使气膜浮动技术有失效的危险。非牛顿液膜浮动技术就是在这种背景下在近几年备受关注的。该文提出了一个新的非牛顿润滑液膜，建立了考虑表面粗糙度影响的非牛顿液膜浮动系统模型，对不同表面粗糙度形状系数进行了仿真研究。研究表明，非牛顿液膜浮动系统的性能与气膜的情况有很大的差异。     

液力挤压高比重钨合金材料的润滑与摩擦

应用流体润滑理论研究了液力挤压大变形高比重穿甲弹芯钨合金材料的润滑与摩擦,并对液力挤压中形成连续滑润膜的必要条件进行了公式推导.结果表明,坯料的表面状态、润滑剂和液体介质的种类影响液力挤压高比重钨合金材料的润滑和摩擦.当坯料用二硫化钼润滑脂润滑并以蓖麻油或其它矿物油作为压力介质时,就可获得最有利的摩擦状态和润滑状态.且当坯锭移动速度达到某一数值以上时,还可以形成连续的滑润膜.而连续滑润膜的形成是实现稳定挤压、改善挤压制品质量、消除粘着滑移的最有效手段.     

Characterization of tribo-layers on self-lubricating plasma-assisted chemical-vapor-deposited TiN coatings

Recently, several new solid lubricants and modern lubrication concepts have been developed to achieve lower friction and wear and thus longer lifetime in severe tribological applications. The aim of this study is to characterize tribo-layers formed during ball-on-disc testing on low-friction, Cl-containing TiN coatings deposited by plasma assisted chemical vapor deposition and to clarify their formation mechanism. Characterization of the transfer layers was done by optical microscopy, optical profilometry, Raman spectroscopy, Auger electron spectroscopy and X-ray photoelectron spectroscopy. Differential scanning calorimetry was used to provide information on the chlorine-influenced chemical reactions of the coatings in ambient air. Iron oxide layers of a thickness in the nm-range have been found on low-chlorine containing TiN coatings (<3 at.% Cl) showing friction coefficients of approximately 0.8, whereas on TiN coatings with higher chlorine contents (>3 at.% Cl) rutile layers were preferably formed, resulting in friction coefficients below 0.2. This self-lubrication mechanism can be explained by the in-situ formation of easy-shearable titanium oxides in the contact zone in the presence of humidity and oxygen.     

Diffusion-limited evaporation of thin polar liquid films

The stability of evaporating very thin films of a polar liquid is investigated. The microscopic interaction with the substrate and capillarity are taken into account in a lubrication equation. The stability of a flat interface is studied when evaporation is limited by the diffusion of the vapour in the gas phase. The evaporation rate is computed and evaporation is shown to be stabilizing. A stability phase diagram is obtained. A weakly nonlinear analysis leads to a film-thickness amplitude equation that is non local in space. Physical consequences of the results are eventually discussed.

粉末冶金静电模壁润滑是一种新颖的润滑方式。本文通过试验研究了在粉末冶金静电模壁润滑技术中润滑剂粉末荷电情况的各种影响因素，包括润滑剂种类、电压和输粉管长度，并对其进行了初步理论分析。结果表明：硬脂酸锌荷电性能最好，不存在荷电阀门值(能使润滑剂粉末荷电的最低电压)，而EBS蜡、W-special蜡及硬脂酸锌和EBS蜡的各种混合粉均存在一荷电阀门值；另外，输粉管长度越短，EBS蜡的荷电阀门值越高，荷电性能越差。
