Structure and microhardness of titanium-based coatings formed by multichamber detonation sprayer

A series of titanium-based coatings (50-550 m thick) on an aluminium substrate was deposited via multichamber detonation sprayer with different barrel lengths (300, 400, and 500, all in mm). The titanium-based coatings obtained in these three experiments were examined by optical microscopy, scanning electron microscopy, and X-ray phase analysi

Deposition and characterization of alumina-titania coating by multi-chamber gas-dynamic sprayer

In this paper, alumina-titania coatings have been formed on aluminium substrate by multi-chamber detonation sprayer. The results show that the alumina-titania coatings consist of both fully melted regions and partially melted regions, and the fully melted region has a lamellar-like structur

Possible interactions in the solar system and synchronism of cyclic variations in solar activity with climatic changes on Earth

Probability of the variant of future development of climate in Europe tovards cooling has been substantiated. Namely, mechanism for redistributing angular momentum of the rotational motion of the solar system (including the Sun) at the expense of this wave component is assumed. Experimental data of foreign and domestic researchers on the impact of distant objects on the motion features of pendulums and rotating mass is confirm the existence of this additional component. Importance of works of O. A. Chyzhevskiy, Maki Takata, Hideo Moriyama and other scientists are denoted in formation of hypothesis on wave interactions in the Solar system. We suggest new land-space experiments, which make possible obtaining additional information to substantiate the statements given in the paper
