抄録

It is difficult to detect the real contact area with lateral size of less than several μm by existing methods. In this study, using a principle of transfer between sputtered films coated on both of contact surfaces, detecting and measuring micro-contacts between a smooth steel ball surface and a smooth glass flat were carried out. It is found that the contours of the contact areas are very clear and the transfers between the two surfaces are supposed to be well done. To check the accuracy of the method, a circle of Hertz contact is detected and measured on a smooth glass surface with high accuracy.
