Ngaso sonke isikhathi lapho sivula umnyango wesithando somlilo embonini ye-powder metallurgy, sibheka izinto ezintathu kuqala: amazinga komoyampilo, ukugcwala kothuli, kanye nokuqhubeka kwesisekelo. Hhayi ngoba isohlwini lokuhlola—kodwa ngenxa yokuthi sake sabona inhlansi emile ithungela ifu lothuli lwe-titanium alloy ngesikhathi sokushintsha kwesisefo. Leso sigameko salolonga kabusha indlela i-QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD. iqeqesha abaqhubi bayo, ihlole izinhlelo zayo zokungenisa umoya, futhi iqinisekise yonke inqwaba ye-AMS 5387 cobalt powder ngaphambi kokuthi ithinte abezindaba. Ukuphepha ekusebenzeni kwefekthri ye-powder metallurgy akubekwe phezu kokukhiqizwa-kwakhelwe ku-geometry of the die, isikhathi somjikelezo wokuhlanza, kanye ne-traceability log elandela indlu yesilinda sephampu ye-piston ukusuka kumpushane eluhlaza ukuya embikweni wokugcina we-CMM.
Uthuli lwensimbi oluvuthayo lulawula iphrofayela yengozi—hhayi intuthu, hhayi ukushisa, kodwa izinhlayiya ezinhle ezilenga emoyeni. I-Aluminium, i-titanium, ama-alloys asekelwe ku-nickel, ngisho nezimpushana zensimbi engagqwali ziziphatha njengophethiloli lapho usayizi wezinhlayiyana wehla ngaphansi kwama-microns angu-100 futhi umoya-mpilo udlula u-12%. Isikhungo sethu esise-Qingdao sigcina umoya-mpilo ongaphansi kuka-8% ngaphakathi kweziko lokucwilisa igesi engasebenzi kusetshenziswa izinzwa ze-paramagnetic zesikhathi sangempela, hhayi izibali-sikhathi noma izilinganiso. Sizilinganisa masonto onke. Singena konke ukuchezuka. Futhi uma umoya-mpilo unyonyoba ngaphezu kuka-9.5% ngaphezu kwamasekhondi angu-45, isistimu izivala ngokuzenzakalelayo nge-nitrogen futhi ikhiyele ngaphandle umnyango wokulayisha kuze kusethwe kabusha isikhulu sezokuphepha esiqinisekisiwe. Lokhu akubona ubunjiniyela obudlulele. Yilokho okugcina imibhobho ye-cobalt-nickel ekubeni imithombo yokuthungela esikhundleni sezingxenye zokulawula ukugeleza.
Ukulawula uthuli kuqala ngaphambi kokuba impushana ingene esakhiweni. Siyenqaba noma iyiphi i-T800 alloy powder lot engenayo ngaphandle kwemibhalo egcwele ye-SDS, ijika lokusabalalisa usayizi wezinhlayiyana (D50 ≤ 42 µm), nokuqukethwe komswakamo < 0.05%—kuqinisekiswe yi-Karl Fischer titration lapho kutholwa. Ukuphatha okungaphakathi kwenqubo kusebenzisa imigqa yokudlulisa evaliwe enomfutho we-nitrogen omuhle, hhayi ama-scoops noma amafaneli. Yonke imigqomo ehlanganisayo izungeza ngaphakathi kwebhokisi legilavu elivalekile elihlanzwe kulo <1% O2. Ama-opharetha agqoka izicathulo ze-conductive ezihlolwa nsuku zonke; ama-tiles aphansi abekwe phansi ku-106 ohms ukumelana max. Uma sisebenzisa umshini wokusansimbi oqediwe noma amapulaki e-cobalt-alloy, sisebenzisa amasistimu okupholisa inkungu—hhayi okokupholisa ngezikhukhula—ukugwema inhlawulo eyinsalela yokufaka umoya emoyeni evaleleke ku-micro-porosity. Ikhasimende lake labuza ukuthi kungani izingxenye zethu zephampu ze-AMS 5387 zibiza u-7% ngaphezu kwezinye izindlela zasogwini. Sibabonise amarekhodi ethu okuhlola iphaneli yokuqhuma kothuli—kanye nohlu lokuhlola lwamaphuzu ayi-14 ngaphambi kokushintshwa kwazo zonke izimpawu zomqhubi ngaphambi kokuthinta umshini wokunyathelisa.
Izici zomuntu zibaluleke kakhulu njengehadiwe. Sithole ukuthi ama-68% acishe aphuthelwe efekthri yethu ye-powder metallurgy kwenzeke ngesikhathi sokunikezwa kweshifu noma ngemva kokusetha kabusha ukulungiswa—izikhathi lapho ukuqapha kwenqubo kwehla. Ngakho-ke sihlele kabusha inqubo yethu ye-lockout-tagout (LOTO): zonke izithando zomlilo manje zidinga ukuqinisekiswa okukabili—uchwepheshe oyedwa uqinisekisa ukuhlukaniswa kwegesi, omunye uqinisekisa ukukhishwa kwamandla kagesi—ngaphambi kokuthi kuvuleke i-hatch yokufinyelela. Sishintshe izimvume zephepha ngokugeleza komsebenzi wedijithali okusekelwe kuthebhulethi okuphoqelela ukubhalwa kwesithombe sobuqotho besihlungi, ukungezwani kwebhande, nokuqhubeka kocingo oluphansi ngaphambi kokuvumela ukuqalisa kabusha kwesisetshenziswa. Akukho okuhlukile. Akukho okukhishiwe. Futhi yonke inkokhelo entsha ichitha amahora wayo wokuqala angama-48 hhayi esiteshini se-CNC, kodwa ifihla umkhondo wethu wokuphepha wasendlini ngesikhathi sokusampula okuyimpushana, ukuhlanzwa kwesisefo, kanye nokubhobolwa kokulahla i-nitrogen okuphuthumayo.
Izimiso zokuphepha ezindaweni zasembonini ye-powder metallurgy zisebenza kuphela uma zingenakuhlukaniswa nokusetshenziswa kobuchwepheshe. Awukwazi ukuhlukanisa "ukuphepha" kusukela ekuqinisekisweni kwe-GD&T, isikhathi sokucwiliswa kokwelashwa kokushisa, noma ukubanzima kokuqedwa kwendawo—ngoba i-porosity ithinta ukugcinwa kothuli, ukuqina kuthinta ingozi yenhlansi yokugaya, kanye nokukhukhuleka kwe-dimensional emzimbeni we-valve yokucindezela kushintsha ukuziphatha kokuvala ngaphansi kokuhamba ngebhayisikili okushisayo. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD., umbiko ngamunye wokuhlola uhlanganisa kokubili imibandela yokudlula/yokwehluleka *kanye* nemethadatha ebaluleke kakhulu yokuphepha: i-powder lot ID, ilogu ye-sintering atmosphere, ubude besikhathi bokuphuma kwe-hydrogen, kanye nogqinsi lwe-oxide engaphezulu kukalwa nge-XPS. Leyo datha ayimanelisi nje i-ISO 9001. Iyasitshela ukuthi lowo mbhobho wengxubevange ye-cobalt uzosinda yini emijikelezweni engu-10,000 ku-high-pressure hydraulic manifold—noma ibe indawo ecashile yokubasa. Ikusasa lingelabakhiqizi abangaphathi ukuphepha njengokuhamba phambili kokuthobelana, kodwa njengengxenye yokuqala yokunemba. Ngoba ekusebenzeni kwefekthri ye-powder metallurgy, ukubekezelelana akukhona nje mayelana nama-microns-kumayelana nemingcele phakathi kokulawula nomphumela.
