The applicability of a tribospectral analysis to the detection of nanoscale inhomogeneities and discontinuities at the nanocoating-substrate interface has been substantiated theoretically. The approach put forward in this work is based on the measurement of the counterbody sliding resistance force coupled with an analysis of its frequency spectrum. A theoretical study on the potentialities and limitations of nanotribospectroscopy has been performed with the use of a computer simulation by the method of movable cellular automata. The results of the investigation have shown, among other things, the possibility to estimate a number of parameters of nanoscale discontinuities (characteristic spacing, linear size, etc.). To obtain reliable information on the defect structure and spacing, nanotribospectroscopy must be supplemented by other diagnostic methods. The design of a prototype nanotribospectrometer with spatial resolution up to 8 nm is described. Applications of the examined approach as a promising nondestructive-testing technique for assessment of nanostructured coating and surface layer damage are discussed.
