TOULOUSE, France - Airbus, mogwirizana ndi Messier Bugatti Dowty, Carpenter Technology ndi Advanced Manufacturing Research Center ku yunivesite ya Sheffield, akupanga kukhwima kwa alloy zitsulo zosapanga dzimbiri zosapanga dzimbiri zomwe zimadziwika kuti "CRES" - kuti zigwiritsidwe ntchito zida zofikira m'tsogolo. Monga gawo la kuwunika kogwirizana, zida zazikulu zisanu ndi zinayi za A320 zidapangidwa muzitsulo zatsopanozi ndipo zimagwiritsidwa ntchito popanga zida zina, kuphatikiza kukhazikitsa zida zomwe zimapangidwa ndikutanthauzira njira yabwino yopangira mafakitale. Kuphatikiza apo, zigawo ziwiri zikupangidwa mpaka 'kumaliza komaliza'. M'tsogolomu, gululi likuyembekeza kusonkhanitsa zida zofikira ku CRES kuti ziwunikire muntchito.
Chitsulo chatsopano cha CRES, chomwe chimapewa kufunikira kogwiritsa ntchito zokutira zachikhalidwe za cadmium ndi chromate, chimapereka kukana kwa dzimbiri ndipo chitha kukhala m'malo mwa zitsulo zonse za carbon zotsika ndi ma aloyi a titaniyamu pazotera zamtsogolo za ndege. Mphamvu zake ndizofanana ndi zitsulo zamakono ndipo zitha kupezeka pamtengo wochepera theka la aloyi a titaniyamu. Zitsulo za CRES zimakwezanso mtengo wa umwini chifukwa cha kuchepa kwa dzimbiri mu ntchito. Kuphatikiza apo, chifukwa cha kuwongolera kwakukulu kwa kulimba kwa fracture ndi kupsinjika kwa dzimbiri kusweka, ndizolimba kwambiri zachilengedwe.
ZOMWE MUNGACHITE PA NKHANIYI:
- The new CRES steel, which avoids the need to use traditional cadmium and chromate coatings, confers intrinsic corrosion resistance and could become an alternative to both existing low-alloy carbon steels and titanium alloys for future aircraft landing gear.
- Airbus, in partnership with Messier Bugatti Dowty, Carpenter Technology and the Advanced Manufacturing Research Centre at the University of Sheffield, are developing the maturity of a new corrosion-resistant stainless steel alloy known as “CRES” – for possible use in future landing gear components.
- As part of the collaborative evaluation, nine A320 main gear components have been forged in the new steel and used for further materials development, including establishing properties of the as-manufactured materials and define the optimum industrialisation route.
