The availability of using nano-technologies for increasing of working capacity the agricultural machinery
The determining importance of nano-industry in socio-economic priorities of industrial countries for preferred production of advanced technology products according to up-to-date phase of economic progress was showed. Within of current concept, it’s integrated assembly which involves equipment, materials, software, knowledge system and also technological, metrological, informational, economic-organizing culture and qualified personnel which ensure the production of advanced technology products based on new, special properties of materials and systems in nanometer range. The intelligent basic of nano-systems – it's, of course, the system of knowledge and skills which is possessed by qualified personnel. The main form of investment in qualified personnel is qualitative and modern education. Together with purely economic problem statement – to improve the efficiency of production based on development of advanced technology industries, it’s necessary to solve one more social problem – to ensure high intellectual level of personnel by way of development of scientific researches and modern education. The important role of the agro-industrial complex in forming of budget and economic stability of Ukraine was underscored. The limiting wear of technological equipment couples (fixed assets) causes additional expenses for repair of equipment and loss of agricultural products. It is pointed on importance to improve the technological equipment reliability along with agricultural measures. The role of wear of main details and couples is specially emphasized. It was proved the advisability of improving reliability and working life of technological equipment and its separate heavy loaded elements and assemblies by using of special strengthening technologies which create nano-crystalline structures on the surfaces of machine elements. The wear resistance laboratory researches of specimens of 65G steel with surface nanostructure in conditions of dry friction were carried out on MI-1M machine according to ring-insert scheme. The researches were held in conditions analogical to working conditions for colters of seeding machines. The advisability of using surface nano-crystalline strengthening by mechanical-pulse treatment technology for improving of wear resistance was showed. The efficiency of using surface hardening due to creation of nano-crystalline structure was showed for colters of seeding machines to improve their working capacity. Abovementioned technology could be used for surface hardening of other elements of agricultural machines, food, processing and other branches of industry.
