Abstract(in English)	An experimental study was carried out to learn about the damage of contacting surfaces through repeated normal loadings without any tangential slip. To achive this purpose, two steel balls with the same size and materials were placed in contact under a cyclically oscilating normal load. Surface damages were observed only in the peripheral annulus of the Hertzian circle, where a contact-separation was repeated; while no damage occurred in the central zone of the Hertzian circle, where the normal stress and the amplitude of the varying pressure were high. The effect of environmental gases and liquids on the damage was also studied.
