Project summary

Objective of the project is the elaboration of new metal-ceramic materials with elevated wear- and high-temperature resistance (HRA 89, sb > 350 MPa at 1000 °C with no dete-rioration of impact and plastic properties) for the fabrication of hard metal tools (dies, press-extruders, cutters, turbine-blades, boring heads and throttles for oil production equipment, etc.). Another goal of the project is the development of technological scheme for the pilot production of developed tools, arrangement and equipment of an appropriate shop, production of experimental batch of the elaborated instruments.

Novelty of the project is in using new dispersion hardened materials, such as cobalt har-dened with highly dispersed particles (<100 mmn) of aluminium or lanthanum oxides, for the bonding of conventional hard alloys based on tungsten and titanium carbides.

The proclaimed goal is realisable if the scientific achievements, experience and equipment of F.N. Tavadze Institute of Metallurgy (Georgian Academy of Sciences) are taken into consideration as starting base. In its turn, this will give an opportunity to create a quite new generation of composites.

Scientific and practical value of the project in case of its realisation is the following:

1. Elaboration of new metal-ceramic composite materials with a remarkable combination of abrasive, high temperature strength and heat-insulating properties of ceramics in combination with plastic and impact properties of metals.

2. Significant increase of the resource and service temperature interval of hard alloys, in particular, creation of a new generation of specially tailored hard-alloy tools, various instruments for the needs of oil-production.

3. Development of technological scheme for the pilot production of elaborated tools (5 - 10 tons per year); arrangement and equipment of an appropriate shop on the territory of the Institute of Metallurgy; production of the experimental batch of the developed instruments ( ~100 kg).

Support of the project can bring great social and economic benefits to Georgia, since, on one side, a team of leading scientists of one of the basic research institutes which was fulfilling mainly the orders of the USSR Defence Organisations, will direct scientific potential to the development of peaceful production at lowest financial expenses (if compared to analogous conventional projects of the same kind). On the other hand, a new scientific branch can be developed for the manufacturing facilities of widely demanded products both in Georgia and world market.
