Beryllium copper, yomwe imadziwikanso kuti copper beryllium, CuBe kapena beryllium bronze, ndi aloyi yachitsulo yamkuwa ndi 0.5 mpaka 3% beryllium, ndipo nthawi zina imakhala ndi zinthu zina zophatikizika, ndipo imakhala ndi magwiridwe antchito azitsulo.

Katundu

Beryllium copper ndi ductile, weldable, ndi machinable alloy.Imalimbana ndi zidulo zopanda oxidizing (mwachitsanzo, hydrochloric acid, kapena carbonic acid), kuzinthu zowola za pulasitiki, kuvala zonyansa komanso kuphulika.Kuphatikiza apo, imatha kutenthedwa ndi kutentha kuti ikhale ndi mphamvu, kulimba, komanso kuwongolera magetsi.

Monga beryllium ndi poizoni pali zovuta zina zokhudzana ndi chitetezo pogwiritsira ntchito ma alloys ake.Mu mawonekedwe olimba komanso omalizidwa, mkuwa wa beryllium ulibe vuto lililonse paumoyo.Komabe, kupuma fumbi lake, monga momwe kumapangidwira pakupanga makina kapena kuwotcherera kungayambitse kuwonongeka kwakukulu kwa mapapo.[1] Mankhwala a Beryllium amadziwika kuti ndi ma carcinogen a anthu akakokedwa.[2] Zotsatira zake, mkuwa wa beryllium nthawi zina umalowedwa m'malo ndi ma aloyi amkuwa otetezeka monga Cu-Ni-Sn bronze.[3]

Ntchito

Mkuwa wa Beryllium umagwiritsidwa ntchito mu akasupe ndi mbali zina zomwe ziyenera kusunga mawonekedwe awo panthawi yomwe amakumana ndi zovuta mobwerezabwereza.Chifukwa cha mphamvu yake yamagetsi, imagwiritsidwa ntchito pazolumikizana zotsika kwambiri zamabatire ndi zolumikizira zamagetsi.Ndipo chifukwa mkuwa wa Beryllium siwopsereza koma wolimba komanso wopanda maginito, umagwiritsidwa ntchito popanga zida zomwe zingagwiritsidwe ntchito m'malo ophulika kapena chifukwa cha EOD.Zida zosiyanasiyana zilipo monga screwdrivers, pliers, spanners, chisel ozizira ndi nyundo [4].Chitsulo china chomwe nthawi zina chimagwiritsidwa ntchito pazida zosayaka ndi aluminium bronze.Poyerekeza ndi zida zopangidwa ndi chitsulo, zida zamkuwa za Beryllium ndizokwera mtengo, osati zolimba komanso zimatha msanga.Komabe, ubwino wogwiritsa ntchito mkuwa wa Beryllium m'malo owopsa umaposa zovuta izi.

Mkuwa wa Beryllium umagwiritsidwanso ntchito kaŵirikaŵiri popanga zida zoimbira zaluso, makamaka maseche ndi makona atatu, kumene amaukonda chifukwa cha kamvekedwe kake komveka bwino komanso kamvekedwe kamphamvu.Mosiyana ndi zida zina zambiri, chida chopangidwa ndi mkuwa wa beryllium chimasunga kamvekedwe kake komanso timbre nthawi yonse yomwe zinthuzo zimagwira."Kumva" kwa zida zotere kumakhala kosangalatsa kwambiri kotero kuti kumawoneka ngati kosayenera kukagwiritsidwa ntchito m'zidutswa zakuda, zomveka bwino za nyimbo zachikale.

Mkuwa wa Beryllium wapezanso kugwiritsidwa ntchito pazida zotsika kwambiri za cryogenic, monga mafiriji a dilution, chifukwa chophatikiza mphamvu zamakina komanso kutenthetsa kwambiri pakutentha kumeneku.

Mkuwa wa Beryllium umagwiritsidwanso ntchito poboola zipolopolo za zida, [5] ngakhale kugwiritsiridwa ntchito kulikonse koteroko kumakhala kwachilendo chifukwa zipolopolo zopangidwa kuchokera kuzitsulo zazitsulo ndizotsika mtengo, koma zimakhala ndi zofanana.

Mkuwa wa Beryllium umagwiritsidwanso ntchito poyezera-pamene-bowola zida pobowola molunjika (slant drilling).Makampani ochepa omwe amapanga zidazi ndi GE (QDT tensor positive pulse tool) ndi Sondex (Geolink negative pulse tool).Aloyi yopanda maginito ndiyofunika chifukwa maginitometers amagwiritsidwa ntchito powerengera omwe adalandira kuchokera pachidacho.

Aloyi

Mphamvu zapamwamba za beryllium zamkuwa zimakhala ndi 2.7% ya beryllium (yoponyedwa), kapena 1.6-2% ya beryllium ndi pafupifupi 0.3% cobalt (yopangidwa).Mkulu wamakina mphamvu zimatheka ndi mpweya kuumitsa kapena zaka kuumitsa.Kutentha kwa ma alloys awa kumakhala pakati pa zitsulo ndi aluminiyamu.Ma alloys amagwiritsidwa ntchito nthawi zambiri ngati zinthu zopangira jekeseni.Ma alloys opangidwa amasankhidwa ndi UNS ngati C172000 mpaka C17400, ma alloys opangidwa ndi C82000 mpaka C82800.Kuwumitsa kumafuna kuziziritsa mwachangu kwachitsulo chopindika, zomwe zimapangitsa kuti beryllium ikhale yolimba mumkuwa, yomwe imasungidwa pa 200-460 ° C kwa ola limodzi, kupangitsa kuti makristasi a beryllide azitha kusungunuka m'matrix amkuwa.Kuchulukitsitsa kumapewa, monga gawo lofananira limapanga makristasi a beryllide ndikuchepetsa kukulitsa mphamvu.Ma beryllides amafanana ndi ma alloys opangidwa ndi opangidwa.

Machulukidwe apamwamba a beryllium amkuwa amakhala ndi beryllium mpaka 0.7%, kuphatikiza faifi tambala ndi cobalt.Matenthedwe awo amatenthetsa bwino kuposa aluminiyamu, pang'ono pang'ono kuposa mkuwa weniweni.Nthawi zambiri amagwiritsidwa ntchito ngati zolumikizira zamagetsi pazolumikizira.
