In 2000 the following two kinds of themes were studied until a micro electro-discharge machine was introduced. Theme 1 : effects of micro indentation pits and micro electrolyzed pits on lubrication characteristics and on pitting durability of medium carbon steel surfaces in rolling-sliding contact. Theme 2 : effects of moving three dimensional nano-textured disc surfaces on thin film gas lubrication characteristics for flylng head slider bearings in magnetic disc storage. The experimental work for Theme 1 revealed that texturing of micro pits improved the oil film creation between the surfaces in contact which successfully led to tough surfaces against pitting^<(1.3.4 and 5)> for Theme 2, computer simulation was carried out to find reasonable arrangement of nano-bumps which minimized the flying height fluctuations^<(2)> After introduction of the micro electro-discharge machine, the research group strived to be endowed with skills to machine micro pits and micro grooves on both flat and … More cylindrical surfaces so as to prepare test pieces for succeeding studies.In 2001 the following three themes were studied using steel surfaces with electro-discharged micro pits or micro grooves. Theme 3 : effects of micro pits on lubrication and pitting durability of medium carbon steel surfaces in rolling-sliding contact. Theme 4 : effects of micro pits on seizure characteristics of a parallel circular thrust bearing in heavily loaded sliding contact. Theme 5 : effects of micro grooves on run-in and seizure characteristics of slider pads on a rotating disc. The experimental results for Theme 3 show that the larger effects should be expected when the total volume of the pits within the contact band is increased. The results for Theme 4 show that the micro pits can lead the surfaces to be strong against seizure, and that the effect is strengthened when the total volume of the pits is increased without notable reduction in the solid area. The results for Theme 5 reveal that better run-in characteristics can be realized when the area of the ridge region becomes small relative to the groove region, and that stronger endurance against seizure can be realized when the area of the ridge region is held large enough by arranging narrow grooves in small pitch.

2000年，人们对以下两种主题进行了研究，直到微细电火花加工设备问世。主题1：微压痕和微电解凹坑对中碳钢表面滚动-滑动接触时的润滑特性和耐蚀性能的影响。主题2：移动三维纳米纹理磁盘表面对磁盘存储中飞行磁头滑动轴承的薄膜气体润滑特性的影响。主题一的实验工作表明，微坑的织构改善了接触表面之间的油膜生成，成功地导致了坚韧的表面抵抗点蚀。对于主题二，进行了计算机模拟，以找到合理的纳米凸起布置，使飞行高度波动最小。在引入微电火花加工设备后，研究组努力掌握在平板和…上加工微坑和微槽的技能。更多的圆柱形表面，以便为后续研究准备试件。2001年，使用带有微放电微坑或微槽的钢表面研究了以下三个主题。主题3：微坑对滚动-滑动接触中碳钢表面的润滑和耐蚀性能的影响。主题4：微坑对重载滑动接触的平行圆形推力轴承卡合特性的影响。主题5：微槽对旋转圆盘上滑块的磨合和卡合特性的影响。针对主题3的实验结果表明，当接触带内凹坑的总体积增大时，将产生更大的影响。对主题4的计算结果表明，微坑可以使表面具有较强的抗咬合能力，并且随着凹坑总体积的增大而固体面积没有明显减小，这种作用增强。对主题5的计算结果表明，当齿脊区域的面积相对于沟槽区域的面积变小时，可以获得更好的磨合特性，而当齿脊区域的面积足够大时，可以通过在小间距处布置窄沟来实现更强的抗卡死耐力。较少
