RESOURCE - SAVING MANUFACTURING TECHNOLOGIES AND THERMAL HARDENING OF MACHINE PARTS AND TOOL

A large range of high-value imported machine-building products is manufactured and operated in Uzbekistan. To reduce costs, it is of interest to use unconventional technologies for the manufacture and hardening of machine parts and tools using energy and material-saving technologies from components produced in the Republic of Uzbekistan. These components include powder materials and polymeric materials produced in Uzbekistan. When using these materials, powder metallurgy and heat treatment methods are applied. As a result of using these methods, four technological problems were formulated and solved: -development of cast metal layered compositions of tool material-structural steel for various types of tools by casting according to gasified models; -development of unconventional methods of thermal hardening of tools made of high-alloy steels to sharply increase their durability and, on this basis, to save alloy steels; -selection of the type of water-soluble polymers produced in the Republic of Uzbekistan for the manufacture of quenching media that replace quenching oils and allow (due to their higher cooling rates) to replace alloyed steels with carbon ones; -development of the composition and technologies for the production of porous cermet products for antifriction purposes from powders obtained from the waste of metallurgical production of the republic.
