Interference coloring of the regular component of a polychromatic light scattered by a colorless dielectric slab with a rough surface is considered. To explain the observed alternation of colors as the depth of roughness grows, we apply the model of a transient layer associated with surface roughness, which extends the well-known analogy between the layer and a light-scattering particle. It is shown that coloring of the forward-scattered component of a white light can be interpreted as the action of a peculiar quarter-wavelength (anti-reflecting) layer for some spectral component of a polychromatic probing beam. By applying the modern chromascopic technique, we compare the coloring of the forward-scattered and the specularly reflected radiation. As the demonstration, the effect of “a blue Moon” and “a red Moon” caused by the spectral changes induced by white-light scattering at the rough surface of a colorless glass is represented. — Natura simplex et fecunda, A.

This paper deals with the formation of wear-resistant antifriction coatings on components of friction couples. We suggest a new antifriction composite material containing nonferrous intermetallic compounds reinforced with explosion-synthesized ultradispersed  diamond, to be used for coating friction surfaces. We report the experimental results and by the example of sleeves of internal combustion engines we show the effieiency of using this material as a function coating for friction couples.

The paper discusses residual stresses in vacuum-plasma-sprayed titanium nitride coatings. It is shown that replacing of continuous coatings with discrete-structured ones reduces residual stresses in them. A decrease in residual stresses depends on the size of a discrete segment: the smaller the segment, the greater this dependence. The approach proposed makes it possible to limit residual stresses in a coating while maintaining its continuity, and to reduce the probability of its contact fracture.

The use of graded coatings, with elastic moduli decreasing gradually from the contact surface to the substrate, is shown to result in considerably reduced stresses at the coating—substrate interface under indentation and friction and sliding contacts subjected to surface loading.
When solving a contact problem, the researchers have demonstrated that the stress distribution pattern, including stresses at the substrate—coating interface, as well as the coating thickness parameters and elastic characteristics depend on the contact plane and relative surface area of the loading zones.The case under study here differs fundamentally from those discussed in the available publications, not so much in considering a coated tool as in the fact that the contact discontinuity depends also on the dimensions of the discrete coating segment. This requires taking up and considering a problem of contact loading of a discrete coating segment on a tool.The objective of the present work is to minimize stresses in the substrate—coating adhesive contact under contact loading with friction.

Production of powder metallurgy is highly dependent on the quality of sintering powder parts, which is characterized by relative density sintering. That is why, quality control? witch based on acoustic sound can determined that the relative density of sintering.. Last years, much attention was paid to determining the relative density of powder melted parts. The connection characteristics of composite materials parts is achieved by extensive using the methods of nondestructive quality control.

For realization a control method for composite materials was proposed new solution based on the using the acoustic signals.
