Abstract:
We look into theoretical and experimental aspects of tribometric interaction between two dielectric substrates with identical surfaces in the course of rapid analysis of their cleanliness. It is shown that if the coefficient of sliding friction equals that of static friction the surface can be defined as being of production grade. The tribometric interaction of the substrates is experimentally shown not to result in a mechanical damage of the surface under study. It is suggested that the device should be complemented by a diffraction grating that generates light pulses. Based on the grating parameters, such as light pulse duration, average sum of three pulses, and degree of their deviation from reference values, the level of substrate surface cleanliness is assessed. The use of the diffraction grating of period T = 63 μm and slit width b = 20 μm is shown to provide a 16-fold increase in the resolution of the tribometric device.

Key words:
surface, dielectric substrates, cleanliness, tribometric device.
