General information
- Short Summary
-
An innovative method of controlled alloying of intermetallic γ-TiAl alloys with carbon has been developed by a team of inventors from Slovak research institute and a well-known Czech university. The novelty of the technology lies in the fact that by using suitable graphite crucibles and controlling the melting and casting parameters it is possible to achieve controlled and reproducible alloying of γ-TiAl alloys with carbon.
The preferred cooperation type are commercial or investment agreement. - Full Description
-
A team of inventors from an established Slovak research institute and Czech university has development by the new method of controlled alloying of intermetallic γ-TiAl alloys with carbon during vacuum induction melting in graphite crucibles. The new method consists in that the alloy is melted in a crucible from isostatically pressed graphite (with defined density, open porosity and average graphite grain size), wherein the melting of the alloy is carried out in a vacuum induction furnace by means of a medium-frequency induction heating with a medium-frequency inductor (with defined power and frequency) in a protective atmosphere of argon at a defined vacuum in the vacuum chamber of the induction furnace. The proposed technology of induction melting combined with centrifugal casting can be used to produce precise castings, e.g. turbocharger wheels for combustion engines, turbine blades or exhaust valves for combustion engines.
The institutions are looking for a partner to cooperate with via commercial agreement or investment agreement. - Advantages and Innovations
-
• lower production price of the product due to the use of graphite crucibles, which have an order of magnitude lower purchase price than Y2O3 crucibles,
• lower purchase price of the melting furnace compared with induction skull melting,
• higher superheating temperature of the melt enabling better fluidity when casting complex thin-walled castings,
• low oxygen contamination during melting compared with ceramic crucibles,
• controllable and reproducible alloying with carbon during melting and casting. - Stage of Development
