TOULOUSE, Lafrans - Airbus, an patenarya ak Messier Bugatti Dowty, Carpenter Technology ak Advanced Manufacturing Research Center nan University of Sheffield, ap devlope matirite nan yon nouvo alyaj asye pur ki reziste korozyon ke yo rekonèt kòm "CRES" - pou itilizasyon posib nan konpozan aterisaj nan lavni. Kòm yon pati nan evalyasyon an kolaborasyon, nèf konpozan Kovèti pou prensipal A320 yo te fòje nan nouvo asye a ak itilize pou plis devlopman materyèl, ki gen ladan etabli pwopriyete nan materyèl yo kòm-fabrike ak defini wout la endistriyalizasyon pi gwo. Anplis de sa, de eleman yo te fabrike nan yon 'fini final'. Nan tan kap vini an, ekip la espere rasanble yon machin aterisaj konplètman CRES pou evalyasyon an sèvis.
Nouvo asye CRES la, ki evite nesesite pou itilize tradisyonèl Kadmyòm ak chromate kouch, konfere rezistans korozyon intrinsèques epi li ta ka vin yon altènativ a tou de ki deja egziste ba-alyaj kabòn asye ak alyaj Titàn pou aterisaj avyon nan lavni. Fòs la se konparab ak asye aktyèl epi li ta ka disponib pou mwens pase mwatye pri a nan alyaj Titàn. Asye CRES tou amelyore pri a nan an komen akòz rediksyon nan korozyon nan sèvis. Anplis, gras a yon gwo amelyorasyon nan severite ka zo kase ak estrès korozyon krak rezistans, yo pi plis anviwònman an gaya.
KISA POU RETIRE NAN ATIK SA A:
- 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.
