MICROINDENTIFICATION OF HARD DISK SURFACE WITH CARBON DIAMOND-LIKE COATING

Dependence of time of recovery of the deformed area around of a print after microindenting surface of a rigid magnetic disk of a personal computer with a carbon diamond-like film thickness of 100 ... 200 nm, deposited by pulse arc discharge method, from thickness of a sheeting and a relative positioning of prints is investigated. The sizes of prints measured with the help scanning probe microscope SMENA-A. The effect of restoration of the deformed surface with a diamond-like carbon coating in 24 and 72 hours is found out. The possible mechanism of the given phenomenon connected to a relaxation of internal stresses of compression in a covering is offered.
