RESEARCH OF POSSIBILITIES OF RE-USE OF CASTING ALLOYS IN ORTHOPEDIC STOMATOLOGY

Abstract

During the casting of products for orthopedic stomatology, there are ingates and profits which are cut off, and are used again only in volume of 10 %. Other parts of ingates and profits aren’t used and goes on recycling. Restriction in a reuse due to that at fusion and molding oxides of cobalt and chrome which have negative influence on mechanical properties of alloys are formed. At that time the design of ingates and profits promotes collecting oxides in this part of foundry system. The way of refinement of cobalt-chrome alloys with AK - 5 allows full use of technological return that renders an essential role on formation of the cost price of manufacturing of tooth artificial limbs. The received results demonstrate that the way of refinement with AK - 5 gives the chance to keep physicomechanical properties of cobalt-chrome alloys received of 70 % of primary structure and 30 % of technological return for use in orthopedic stomatology.
