Title: | Nanocomposites for hybrid and ceramic bearings |
Type of product: | Release of new product: materialParts for hybrid and ceramic bearings (balls,rolls. rings) |
Description: | Energy efficient technology of rate-controlled sintering has been developed. Dense wear-resistant nanoceramics parts (dry friction coefficient 0.2-0.4 , wear rate <10-6 mm3/Nm, grains size 50-70 nm) based on silicon nitride have been produced. |
Technical advantages: | Developed material twice time better in comparison with traditional ceramics for bearings. Possibility to utilize friction units under subzero and at extremely high temperatures in aggressive mediums (work temperatures -60 C up to 1200 С) |
The economic benefits: | Implementation of developed in IPMS technologies for production of wearproof nanocomposites, allow to achieve high-quality nanostructural parts which can compete at price with the Asian analogues. The calculated reference cost for unit of wearproof part from a nanocomposite with weight 5 g showed that it is twice chipper then analog |
The impact on the environment. Environment: | Utilization of up-to-date SPS and RCS technologies for production of the nanoceramic bearings allow to decrease energy consumption on 10-20%. |
The stage of completion: | Prototypelaboratory scale party of samples fron nanocomposites based on ceramic parts were consolidated by rate controlled and spark plasma sintering technologies. Estimated grains size of fully dense ceramics are ~50-200 nm |
Implementation: | not implemented |
Intellectual Property Rights: | Apply for a patentUA patent № 200512813 Thermochemical treatment of high melting point compounds in the gas flow |
Forms and conditions of transfer of products: | Co-productionCreation of startup company on producing of the ceramic bearing (flexibility and adaptivity at the market)
Necessary primary investments are 2,5 million USD
