Ma aloyi a Titaniyamu ali ndi zida zamakina abwino kwambiri koma osachita bwino, zomwe zimabweretsa kutsutsana kuti chiyembekezo chawo chogwiritsa ntchito ndikulonjeza koma kukonza ndikovuta.M'nkhani ino, kusanthula zitsulo kudula ntchito titaniyamu aloyi zipangizo, pamodzi ndi zaka zambiri zothandiza ntchito zinachitikira, kusankha titaniyamu aloyi kudula zida, kutsimikiza kudula liwiro, makhalidwe a njira zosiyanasiyana kudula, machining malipiro ndi njira zodzitetezera. amakambidwa.Ikufotokoza malingaliro anga ndi malingaliro anga pakupanga ma aloyi a titaniyamu.
Titaniyamu alloy ali otsika kachulukidwe, mkulu mphamvu yeniyeni (mphamvu / kachulukidwe), kukana dzimbiri bwino, kukana kutentha kwambiri, kulimba bwino, plasticity ndi weldability.Titaniyamu aloyi akhala akugwiritsidwa ntchito kwambiri m'madera ambiri.Komabe, kusayenda bwino kwa matenthedwe, kulimba kwambiri, komanso kutsika kotanuka modulus kumapangitsanso ma alloys a titaniyamu kukhala chitsulo chovuta kukonza.Nkhaniyi ikufotokoza mwachidule njira zina zaumisiri pakupanga ma aloyi a titaniyamu kutengera mawonekedwe ake aukadaulo.
Ubwino waukulu wa titaniyamu aloyi zipangizo
(1) Titaniyamu alloy ali ndi mphamvu zambiri, kachulukidwe kakang'ono (4.4kg / dm3) ndi kulemera kochepa, komwe kumapereka yankho lochepetsera kulemera kwa zigawo zina zazikulu zapangidwe.
(2) Kutentha kwakukulu.Titaniyamu aloyi akhoza kukhalabe mphamvu mkulu pansi chikhalidwe cha 400-500 ℃ ndipo akhoza ntchito stably, pamene kutentha ntchito aloyi zotayidwa akhoza kukhala pansi 200 ℃.
(3) Poyerekeza ndi chitsulo, chibadidwe mkulu dzimbiri kukana titaniyamu aloyi akhoza kupulumutsa mtengo ntchito tsiku ndi kukonza ndege.
Kusanthula kwa machitidwe a makina a titaniyamu aloyi
(1) Low matenthedwe madutsidwe.Thermal conductivity ya TC4 pa 200 ° C ndi l = 16.8W / m, ndipo matenthedwe matenthedwe ndi 0.036 cal / cm, yomwe ndi 1/4 yokha yachitsulo, 1/13 ya aluminium ndi 1/25 yamkuwa.Mu kudula, kutentha kwa kutentha ndi kuzizira kumakhala kosauka, komwe kumafupikitsa moyo wa chida.
(2) The zotanuka modulus ndi otsika, ndipo machined pamwamba pa gawo ili ndi rebound lalikulu, zomwe zimabweretsa kuwonjezeka kukhudzana malo pakati pa makina pamwamba ndi mbali pamwamba pa chida, zomwe sizimangokhudza kulondola kwa dimensional. gawo, komanso amachepetsa chida durability.
(3) Ntchito yachitetezo panthawi yodula ndiyosauka.Titaniyamu ndi chitsulo choyaka moto, ndipo kutentha kwambiri ndi zowala zomwe zimapangidwa panthawi yodula pang'ono zimatha kuyambitsa tchipisi ta titaniyamu.
(4) Chinthu cholimba.Titaniyamu aloyi ndi otsika kuuma mtengo adzakhala povutirapo pamene Machining, ndi tchipisi amamatira m'mphepete kudula angatenge nkhope ya chida kupanga anamanga m'mphepete, zimene zimakhudza Machining zotsatira;ma aloyi a titaniyamu okhala ndi kuuma kwakukulu amakhala tcheru kuti aphwanye komanso abrasion chida panthawi yokonza.Makhalidwewa amachititsa kuti zitsulo zochepetsera kuchotsa titaniyamu alloy, zomwe ndi 1/4 yokha ya chitsulo, ndipo nthawi yokonza ndi yotalikirapo kuposa chitsulo chofanana.
(5) Kugwirizana kwamphamvu kwamankhwala.Titaniyamu sangakhoze kokha mankhwala anachita ndi zigawo zikuluzikulu za nayitrogeni, mpweya, mpweya monoxide ndi zinthu zina mu mlengalenga kupanga owumitsidwa wosanjikiza wa TiC ndi tiN pamwamba pa aloyi, komanso anachita ndi zinthu chida pansi pa kutentha kwambiri. zinthu kwaiye ndi ndondomeko kudula, kuchepetsa chida kudula.za kukhazikika.
