COMBINED PLANTING OF ANNUAL CROPS - IMPORTANT PROBLEM OF PRACTICAL ECOLOGY
DescriptionSelf-regulation of agricultural systems is based upon taking into account the interaction of their components released in variety of species and trophic relations; agricultural systems is diversified in towards a sustainable, productive and strategic development of the systems; one of the most promising areas of diversification of agricultural systems is considered to be an introduction to the practice of combining crops, known in agriculture for a long time, which shows us the nature. The most developed technology for creating combined crops is the practice of creating mixtures and the nature of the relationship between their different components

FORMATION OF SURFACE LAYERS OF NANOSTRUCTURED TINICO, STIMULATED WITH MECHANICAL ACTIVATION
DescriptionThis article presents a complex method of formation of the surface-modified layers of materials with shape memory effect, including high-speed flame spraying powders TiNiCo with a cobalt content of 2 and 5%, subsequent thermal and thermomechanical treatment, allowed forming nanostructured surface layers with a high level of functional and operational properties. It is shown that the TiNiCo complex processing layer allowed reducing the porosity of coatings and increasing the strength of adhesion of the coating to the substrate. Surface modification TiNiCo for optimal regimes allowed increasing fatigue life under high cycle loading by 30-40% and wearing 3-3.5 times. Based on comprehensive research metallophysical surface layers obtained new information on the nanoscale composition
