Akatswiri opanga zakuthambo amafunikira ma turbine masamba omwe amakhala ndi ± 0.05 mm kulolerana pa 1,200 ° C - kapena nyumba zamafuta omwe amakhala ndi moyo maola 30,000 popanda kufalitsa kwa microcrack - samayamba ndi mawu oyambira. Amayamba ndi machitidwe akuthupi, mbiri yamatenthedwe, ndi kukhazikika kwapang'onopang'ono pamayendedwe a kutentha. Chifukwa chake Investment kuponyera Azamlengalenga fakitale maubwenzi samachita bwino pamakatalogu okha. Amadalira kulanga kwazitsulo, kuwonetsetsa kuwonekera, ndi luso logwiritsa ntchito ma alloys monga AMS 5387 cobalt-chromium ndi T800-grade superalloys-zida zomwe zimatsutsa makina koma zimafuna kulondola kwa mawonekedwe a ukonde.
Tawona ma projekiti ambiri akuyimilira pakuyenerera chifukwa nyumba yoponyamo idawona zida zamlengalenga ngati "ntchito ina yolekerera kwambiri." Pampu ya kasitomala m'modzi ya AMS 5387 idalephera kuyesa kugwedezeka, osati kuchokera ku zolakwika zamapangidwe, koma kuchokera kumagulu osagwirizana a tirigu pamagulu onse. Chifukwa chake? Wopereka katundu yemwe adapeza ma ingots a faifi wa cobalt popanda chiphaso cha batch-level, kenako adalumpha kutsimikizira kowonjezera. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timachita chilichonse chowulutsa mumlengalenga ngati thermomechanical system-osati mawonekedwe achitsulo. Malo athu ogwirizana ndi ISO ku Qingdao amayendetsa ndalama zonse: kusonkhana kwa sera, nyumba ya zipolopolo za ceramic, kupukuta, kuwombera kosasunthika, kutsanulira mwatsatanetsatane pansi pa argon, ndi chithandizo cha kutentha kwapambuyo ndi nthawi yeniyeni yodula mitengo ya thermocouple. Palibe sitepe ndi outsourced. Palibe zambiri zomwe zimataya kutsata.
Chomwe chimalekanitsa ntchito yopangira ndalama zamlengalenga kuchokera ku cholinga chambiri si zida zokha - ndi momwe kuponyera kumalumikizirana ndi njira zakutsika. Timayika 72% ya zowulutsa zathu zakuthambo m'nyumba pogwiritsa ntchito malo a 5-axis CNC omwe amawunikidwa tsiku lililonse kukhala ISO 10360-2. N’chifukwa chiyani zimenezi zili zofunika? Chifukwa thupi la cobalt alloy valve loponyedwa ku ± 0.3 mm silingathe kupirira ID yomaliza ya ± 0.025 mm pokhapokha makina opangira makinawo akuwonetsanso malo omwewo omwe adakhazikitsidwa pakusokonekera kwa nkhungu. Mainjiniya athu amapanga zipata zoponyamo ndi zokwera * ndi * makina omaliza amalingaliro - osati pambuyo pake. Mwachitsanzo, popanga ma piston pampu ya silinda yama hydraulic actuation system, timayika zodyetsa kuti zichepetse kupsinjika kotsalira m'makoma obowola, kenako makina amkati amkati pogwiritsa ntchito zida za carbide zomwe zimafanana ndi kuuma kwapamwamba. Kuphatikizikako kumachepetsa zochepa ndi 41% pazomanga zamagawo oyamba poyerekeza ndi mashopu omwe kuponya ndi kupanga makina amagwira ntchito ngati madipatimenti a siled.
Ena angatsutse kuti kuponya mchenga kumapereka kusintha kwachangu kwazinthu zazikulu zakuthambo. Koma pamipanda yopyapyala, ma geometri ovuta - monga zigawo za turbine shroud kapena zomangira zipinda zoyatsira moto - kuponya ndalama kumakhalabe kosasinthika. Mchenga nkhungu zimalimbana ndi makulidwe a khoma pansi pa 4 mm; zipolopolo za ceramic zimagwira 1.8 mm nthawi zonse. Choyipa kwambiri, kuponyera mchenga kumabweretsa ziwopsezo zophatikizika za silika zomwe zimasokoneza moyo wotopa pazinthu zozungulira. Timatsimikizira gulu lililonse lazamlengalenga kudzera pa X-ray tomography-osati ma radiography okha-ndipo timakana chibowo chilichonse choposa ASTM E192-22 Level 2 porosity. Chaka chatha, makasitomala awiri adasiya ogulitsa aku Europe atapeza mafilimu obwerezabwereza a subsurface oxide m'milomo yawo ya cobalt alloy. Njira yathu imagwiritsa ntchito vacuum degassing pre-pour ndi kuzizira kozizira kosachepera 100°C/ola kudzera mu gamma-prime solvus—kuchotseratu mafilimuwo.
Ogula zamlengalenga samangofunika magawo. Amafunikira umboni wokonzekera kuwunika: ma cert azinthu okhala ndi kusanthula kwathunthu kwa kutentha kwamankhwala, malipoti a CMM omangirizidwa ku ma callout a GD&T pazithunzi za ASME Y14.5, zipika zochizira kutentha zomwe zidasindikizidwa ndi akatswiri azitsulo ovomerezeka, ndi zolemba zosawononga zoyesa ku NADCAP AC7108 Rev. F. momwe mungayang'anire, tsitsani malipoti ovomerezeka, ndikutsata zopotoka zotsutsana ndi ma chart owongolera a SPC. Pakupanga ma prototype mwachangu, timapondereza kuzungulira kwa kujambula mpaka kutumizidwa kwa nkhani yoyamba mpaka masiku 14 ogwirira ntchito - osadumpha nthawi yowumitsa zipolopolo kapena kufupikitsa njira zolumikizira. Liwiro limenelo limachokera ku njira yowonda yogwirira ntchito, osati masitepe osokonekera.
Ngati gawo lanu lotsatira lazamlengalenga likufuna AMS 5387 cobalt alloy, T800-based geometry, kapena zoponyera zitsulo zosapanga dzimbiri zokhala ndi zowoneka bwino zomwe zimafunikira Ra ≤0.4 µm - timazipanga kuti zigwire ntchito, osati kungodutsa. Osati ngati zinthu zapashelufu, koma monga machitidwe opangidwa mwaluso opangidwa mobwerezabwereza, olembedwa, komanso oyankha mwazitsulo. Pitani ku https://www.tsingtaocnc.com kuti muwunikenso luso laukadaulo, kupempha malipoti oyeserera, kapena kukonza zowunikira ndi gulu lathu lophatikiza makina opangira makina. Kulondola muzamlengalenga kumayamba kale kutsanulira - ndipo kumatha kokha pamene gawo lililonse, mawonekedwe ang'onoang'ono, ndi magwiridwe antchito akukhudzana ndi cholinga chofunikira kwambiri pakuwuluka.
