Ngalo lonke ixesha sivula umnyango wesithando somlilo kumzi-mveliso wesinyithi wesinyithi, sijonga izinto ezintathu kuqala: amanqanaba eoksijini, ugxininiso lothuli, kunye nokuqhubekeka komhlaba. Akunjalo ngenxa yokuba ikuluhlu lokutshekisha-kodwa ngenxa yokuba sakha sabona intlantsi emileyo ivutha ilifu lothuli lwe-titanium alloy ngexesha lokutshintsha kwesisefo. Eso siganeko satshintsha indlela QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iqeqesha abaqhubi bayo, iphicothe iinkqubo zayo zokungenisa umoya, kwaye iqinisekisa yonke ibhetshi ye-AMS 5387 cobalt powder ngaphambi kokuba ichukumise umshicileli. Ukhuseleko kwimisebenzi yefektri ye-metallurgy ye-powder ayifakwanga phezulu kwimveliso-yakhiwe kwijometri yokufa, ixesha lomjikelezo wokuhlanjululwa, kunye ne-log traceability log elandela indlu nganye ye-piston pump cylinder ukusuka kwi-powder eluhlaza ukuya kwingxelo yokugqibela ye-CMM.
Uthuli lwesinyithi olunokutsha lulawula iprofayili yengozi—kungekhona umsi, kungekhona ubushushu, kodwa amasuntswana amahle axhonywe emoyeni. I-aluminiyam, i-titanium, i-alloys esekwe kwi-nickel, kunye nomgubo wensimbi engenasici ziziphatha njenge-fuel xa ubungakanani besuntswana lehla ngaphantsi kwe-100 microns kunye ne-oxygen idlula i-12%. Indawo yethu eQingdao igcina ioksijini engaphantsi kwe-8% ngaphakathi kwiziko le-inert-gas sintering sisebenzisa izinzwa zeparamagnetic zexesha lokwenyani, hayi izibali-xesha okanye uqikelelo. Sizilinganisa ngeveki. Siloga yonke intembuko. Kwaye ukuba i-oksijini ihamba ngaphezu kwe-9.5% ngaphezu kwemizuzwana ye-45, inkqubo iyazicima ngokuzenzekelayo nge-nitrogen kwaye ivale umnyango wokulayisha kuze kube yilapho usetwe ngokutsha ngegosa lokhuseleko eliqinisekisiweyo. Oku asikobunjineli obugqithisileyo. Yiloo nto egcina imilomo ye-cobalt-nickel ekubeni yimithombo yokutshisa endaweni yezinto zokulawula ukuhamba.
Ulawulo lothuli luqala phambi kokuba umgubo ungene kwisakhiwo. Siyala nayiphi na i-T800 ye-alloy powder lot engenayo ngaphandle kwamaxwebhu apheleleyo e-SDS, ubungakanani be-particle ye-curve yokusabalalisa (D50 ≤ 42 µm), kunye nomxholo wokufuma <0.05%-iqinisekiswe nguKarl Fischer titration xa ifunyenwe. Ukuphathwa kwenkqubo kusetyenziswa imigca yokudlulisa etywiniweyo enoxinzelelo lwenitrogen, hayi izikophu okanye iifunnels. Lonke igubu lokudibanisa lijikeleza ngaphakathi kwebhokisi yeglavu evalelweyo ecocwa kuyo <1% O2. Abaqhubi banxiba izihlangu ezihambayo ezivavanywa yonke imihla; iithayile zomgangatho zibekwe kwi-106 ohms ukumelana max. Xa umatshini sigqiba ukuphoswa kwentsimbi okanye iiplagi ze-cobalt-alloy, sisebenzisa iinkqubo zokupholisa inkungu-kungekhona ukupholisa kwamanzi-ukunqanda i-aerosolizing intsalela yezohlwayo ezibanjwe kwi-micro-porosity. Umthengi wakha wabuza ukuba kutheni iinxalenye zethu zempompo ze-AMS 5387 zibiza i-7% ngaphezulu kunezinye iindlela ezingaselunxwemeni. Sababonisa iirekhodi zethu zovavanyo lwepaneli yokuqhuma uthuli-kunye ne-14-point pre-shift checklist yokuhlola zonke iimpawu zabaqhubi ngaphambi kokuchukumisa umshicileli.
Izinto zabantu zibaluleke kakhulu njengehardware. Sifumene ukuba i-68% yokuphoswa kufutshane kwifektri yethu ye-metallurgy yenzeke ngexesha lokunikezelwa kweshifti okanye emva kokusetha kwakhona ulungiso-amaxesha apho inkqubo yokuqaphela idipha. Ke sihlengahlengise inkqubo yethu yokutshixa (i-LOTO): zonke iziko lokutshisa ngoku zifuna ukuqinisekiswa kabini-ingcali enye iqinisekisa ukwahlukaniswa kwegesi, enye iqinisekisa ukucinywa kombane-ngaphambi kokuba i-hatch yokufikelela ivuleke. Siye satshintsha iimvume zephepha ngokuqhutywa kwedijithali esekwe kwithebhulethi enyanzelisa ukubhalwa kweefoto zesihluzi semfezeko, ukuxinana kwebhanti, kunye nokuqhubekeka kocingo olusezantsi ngaphambi kokuvumela isixhobo siqale kwakhona. Akukho ngaphandle. Akukho kubhala ngaphezulu. Kwaye yonke ingqesho entsha ichitha iiyure zabo zokuqala ezingama-48 hayi kwisikhululo se-CNC, kodwa isithunzi sethu sokhuseleko lwangaphakathi endlwini ngexesha lesampulu yomgubo, ukucocwa kwe-sieve, kunye ne-nitrogen yokulahla i-drill engxamisekileyo.
Iiprothokholi zokhuseleko kwindawo yefektri yesinyithi yomgubo zisebenza kuphela xa zingohlulwa kukubulawa kobugcisa. Awunako ukwahlula "ukhuseleko" kuqinisekiso lwe-GD&T, ixesha lokufunxa ubushushu, okanye uburhabaxa bokugqiba umphezulu-kuba i-porosity ichaphazela ukugcinwa kothuli, ukuqina kuchaphazela umngcipheko wentlantsi yokusila, kunye nokukhukuliseka okubonakalayo kumzimba wevalve yoxinzelelo kutshintsha indlela yokuziphatha yokutywina phantsi kwebhayisekile eshushu. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD., ingxelo nganye yokuhlolwa ibandakanya zombini indlela yokupasa/yokusilela *kunye* nemetadata ebaluleke kakhulu yokhuseleko: i-ID yepowder lot, i-sintering atmosphere log, ubude bexesha lokubhaka le-hydrogen emva kwe-sintering, kunye nobungqingqwa be-oxide yomphezulu obulinganiswa nge-XPS. Loo datha ayimanelisi nje i-ISO 9001. Isixelela ukuba loo mlomo wengxubevange ye-cobalt uya kusinda kwimijikelo ye-10,000 kuxinzelelo oluphezulu lwe-hydraulic manifold-okanye ibe yindawo yokuvutha efihlakeleyo. Ikamva lelabavelisi abaphatha ukhuseleko hayi njengokuthotyelwa phezulu, kodwa njengomgangatho wokuqala wokuchaneka. Ngenxa yokuba kwimisebenzi yefektri ye-metallurgy, ukunyamezela akukhona nje malunga nee-microns-kumalunga nemida phakathi kolawulo kunye nesiphumo.
