“…Очевидно, обеспечение качества изделия в целом невозможно без обеспечения качества этих многочисленных контактных соединений, которое в свою очередь в значительное степени является функцией качества контактирующих поверхностей. Не удивительно, что качеству поверхности уделяется большое внимание [1][2][3][4].…”

Исследована нанотопография технических поверхностей деталей из высоколегированной термообработанной стали и электротехнического серебра после финишной механической обработки. Экспериментально определены функции плотности вероятности параметров нанотопографии - высот выступов и радиусов кривизны их вершин, которые необходимы для теоретического описания процессов контактного взаимодействия технических поверхностей (на примере поверхностей серебра и стали). Установлено, что распределение указанных параметров наношероховатости сильно асимметрично и далеко от нормального. Доказано, что для исследованных поверхностей плотность вероятности указанных параметров наношероховатости адекватно описывается бета-распределением. Достоверность данного заключения подтверждается с помощью критериев согласия Пирсона χ и Романовского. The nanotopography of engineering surfaces of machine parts made of high alloy heat-treated steel and electric silver after finishing mechanical treatment was studied. The probability density functions of the nanotopography parameters - the heights of peaks and the radii of curvature of their vertices - were experimentally determined. These parameters are necessary for theoretical description of processes of the contact interaction of engineering surfaces (exemplifying on surfaces of silver and steel). It is established that the distributions of the above mentioned nanoroughness parameters are essentially asymmetrical and are far from normal ones. It has been proved that for the studied surfaces the probability densities of the above mentioned nanoroughness parameters are adequately described by the beta-distribution. The validity of this conclusion is confirmed by the fitting criteria such as χ (K. Pearson’s criterion) and Romanovsky’s criterion.
