TOULOUSE, Farani - ʻO Airbus, ma ka hui pū ʻana me Messier Bugatti Dowty, Carpenter Technology a me ka Advanced Manufacturing Research Center ma ke Kulanui o Sheffield, ke hoʻomohala nei i ke oʻo ʻana o kahi hui kila kuhili-kūpaʻa hou i kapa ʻia ʻo "CRES" - no ka hoʻohana ʻana i loko. nā mea hoʻopaʻa pae e hiki mai ana. Ma ke ʻano o ka loiloi like ʻana, ua hana ʻia nā ʻāpana ʻeiwa A320 i loko o ke kila hou a hoʻohana ʻia no ka hoʻomohala ʻana i nā mea hou aku, me ka hoʻokumu ʻana i nā waiwai o nā mea i hana ʻia a wehewehe i ke ala ʻoihana ʻoi loa. Eia kekahi, ke hana ʻia nei nā ʻāpana ʻelua i kahi 'hopena hope'. I ka wā e hiki mai ana, manaʻolana ka hui e hōʻuluʻulu i kahi pahu pae CRES piha no ka loiloi i ka lawelawe.
ʻO ke kila CRES hou, e pale ana i ka pono e hoʻohana i ka cadmium kuʻuna a me ka chromate coatings, hāʻawi i ke kūpaʻa ʻana i ka corrosion intrinsic a hiki ke lilo i mea ʻokoʻa i nā kila kalapona haʻahaʻa haʻahaʻa a me nā alloys titanium no nā mea hoʻokele mokulele e hiki mai ana. Hoʻohālikelike ka ikaika i nā kila o kēia manawa a hiki ke loaʻa ma lalo o ka hapalua o ke kumukūʻai o nā alloys titanium. Hoʻomaikaʻi nā kila CRES i ke kumukūʻai o ka ʻona ma muli o ka hōʻemi ʻana o ka corrosion in-service. Eia kekahi, mahalo i ka hoʻomaikaʻi nui ʻana i ka paʻakikī o ka haʻihaʻi a me ke koʻikoʻi o ka corrosion cracking resistance, ua ʻoi aku ka paʻa o ke kaiapuni.
He aha e lawe ʻia mai kēia ʻatikala:
- 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.
