Tribotechnical properties of sintered bronze strengthened by aluminide of Ti–46Al–8Cr
Source abstract
Abstract
The influence of ultrafine powder Ti–46Al–8Cr intermetellic addition obtained by MASHS on tribotechnical properties of Bro10 sintered bronze has been investigated. The addition of aluminide makes it possible to decrease the instantaneous friction coefficient of sintered bronze under concentrated loading upon friction with 40X hardened steel by 1.2–1.3 times upon continuously increasing loads by two times and to reduce temperature in the friction area by 1.15–1.6 times while increasing the wear resistance by 20 times upon permanent loadings and by 35–40 times upon continuously increasing loading.
