Mechanism of Boundary Lubrication and it's Application for Manufacturing Fine Surface

设计了一台滚动摩擦试验机，研究了边界润滑机理，阐明了板料滚动方向与摩擦行为的关系。另一种摩擦试验机--U型弯曲摩擦试验机也被设计出来，以弄清摩擦条件与产品减薄机理之间的关系。结果表明：1）要减小轧制方向对摩擦性能的影响，必须提高工作速度和润滑剂的粘度，降低材料表面粗糙度; 2）要获得薄壁的产品，必须确定最佳的润滑条件和退火条件。通过研究，阐明了这些条件，并指出了生产0.1mm厚无缝钢管的可能性.

A rolling - type tribometer has been devised to investigate the boundary lubrication mechanism and clarified the relation between the rolling direction of sheet and friction behavior. Another type of tribometer, U-bending type tribometer has also devised to make dear the relation of frictional condition and thinning mechanism of products. The following results are obtained.1) To diminish the effect of rolling direction on frictional behavior, it is necessary to increase the working velocity and viscosity of lubricants and to decrease of surface roughness of materials.2) To establish the best lubrication conditions and annealing conditions is very important to produce a very thin wall of products. Through this research, these conditions are clarified and possibility of producing 0.1 mm - thickness seamless pipe is shown.
