stellite 21 gawo

Magawo a Stetellite 21 amalephera - osati kuchokera ku kapangidwe kolakwika, koma kuchokera kumalingaliro osinthidwa olakwika. Tawonapo magulu atatu a pampu a hydraulic akugwira mkati mwa maola 48 akhazikitsidwa chifukwa cholowa m'malo stellite 21 gawo zimafanana ndi miyeso yodziwika, osati kukhazikika kwa microstructure kapena kugawa kwa carbide. Icho si cholakwika cha makina. Ndi kulephera kwa machitidwe azinthu.

Chifukwa chiyani Kusintha kwa Stellite 21 Sikuti "Sinthani ndi Kupita"

Stellite 21 ndi aloyi ya cobalt-chromium-tungsten yowumitsidwa ndi eutectic carbides-M.₇C₃ ndi M₂₃C₆- zomwe zimathandizira kukana kwambiri kuphulika, kuyabwa, komanso kutentha kwambiri kwa okosijeni. Koma kagwiridwe kake kamadalira pamitundu inayi yosasinthika: kuchuluka kwa kulimba pakuponya, kuzungulira kwa kutentha kwa pambuyo pa weld, kupitilizabe kwa carbide pamtunda wovala, ndi mawonekedwe azitsulo zomangirira pazovala kapena zokutira.

M'magawo enieni padziko lapansi, timayezera kuuma kopitilira 120 HV kuzama kwa 0.5 mm m'malo osasinthidwa bwino. Ichi ndichifukwa chake 73% ya zolephera msanga zomwe timapeza zimabwereranso ku chifukwa chimodzi: gawolo lidapangidwa kuchokera kuzitsulo zomwe zidapangidwa m'malo mopanga zolimba. Zinthu zogwiritsidwa ntchito zilibe netiweki yolumikizana ya carbide yomwe imafunikira kuti tinthu ting'onoting'ono ting'onoting'ono ting'onoting'ono ting'onoting'ono tapampu kapena mipando ya valve.

AMS 5387 imatchula kagawo kakang'ono ka carbide (22-28%), chromium content (27-31%), ndi tungsten range (3.5-5.5%). Komabe ogulitsa ambiri amatumiza magawo ovomerezeka ku AMS 5387 pomwe akupereka chemistry yeniyeni m'mphepete mwam'munsi-yogwirizana ndi mankhwala, yosokonekera. Timatsimikizira gulu lililonse ndi mawonekedwe a OES ndi mapu a SEM-EDS amitundu yonse asanatulutsidwe.

Protocol Yamagawo Anayi Omwe Amalepheretsa Kutsika Kwambiri

Akatswiri athu a m'munda adapanga ndondomekoyi atatha kuthandizira zowonjezera zowonjezera 142 pamagulu onse opangira mafuta, ma winchi amadzimadzi amadzimadzi, ndi mapampu a piston. Imagwira ntchito chifukwa imagwira m'malo ngati ntchito yophatikizira - osati gawo logula zinthu.

• Gawo 1: Interface Audit - Yezerani kuuma kwa gawo lapansi, kuuma kwa pamwamba (Ra ≤ 0.8 µm), ndi mbiri yotsalira ya nkhawa. Stellite 21 zokutira zimachedwetsa ngati kulimba kwa gawo lapansi kupitilira 35 HRC popanda interlayer nickel buffer.
• Gawo 2: Kutsimikizika kwa Geometry - Tsimikizirani ma radii ofunikira, ma angle a chamfer, ndi kutsetsereka kwa pamwamba pogwiritsa ntchito makina oyezera. Kupatuka kwa 0.015 mm mu utali wampando kumawonjezera kukakamiza kolumikizana ndi 40% mu mavavu opumira.
• Gawo 3: Metallurgical Match - Tsimikizirani carbide morphology kudzera muzitsulo. Mapangidwe ovomerezeka akuwonetsa mosalekeza, olumikizidwa a M₇C₃ maukonde-osati zilumba zakutali kapena ma dendrite ogawika.
• Gawo 4: Kuwotcha mkati mogwira ntchito - Thamangani pansi pa katundu wolamulidwa kwa mphindi 30 pa 60% max rated max musanayambe kukwera. Kuwunika kutentha kukwera kudutsa mawonekedwe; >12°C delta imawonetsa kusalumikizana kokwanira kwa kutentha.

Pamene Magawo a Catalogue Afupikitsidwa-ndi Zomwe Muyenera Kuchita M'malo mwake

Ena angatsutse kuti mbali 21 za stellite 21 zimachepetsa nthawi yotsogolera ndi mtengo. Komabe, zinthu zamtundu wanthawi zonse sizigwirizana ndi mbiri yakale yamafuta, mawonekedwe a carbide, kapena mawonekedwe osinthira omwe amafunikira pakugwiritsa ntchito zofunikira kwambiri. Tinalowa m'malo mwa mphuno ya aloyi ya cobalt yomwe inalephera mu mpope wa jekeseni wamankhwala wothamanga kwambiri pomwe gawo la OEM lidatenga maola 87. Choloŵa m'malo choyamba - chochokera kwa ogulitsa ma generic - chinalephera m'maola 19. Choyambitsa? Kupatukana kwa Carbide pansonga chifukwa cha kulimba kosayenera pakuponya.

Tinathetsa izi posinthira njira yopangira makonda: kuyika ndalama zokhala ndi vertical mold orientation, kutsatiridwa ndi kuphatikiza kwa HIP ndi kulondola kwa CNC kuyatsa ma lathe amitundu yambiri. Gawo lomaliza lidapereka maola 412 othamanga—4.7× OEM moyo. Zothandizira makiyi: kuyanjanitsa kwambewu kufananiza komwe kumayendera, kupitilira kwa carbide kumatsimikiziridwa ndi kusanthula kwapang'onopang'ono kwa CT, ndi kumalizidwa kwapamtunda kumagwira Ra 0.2 µm pamalo osindikizira.

Izi sizongoyerekeza. Ndizobwerezabwereza. Ndipo pamafunika kuwongolera zonse zamtengo wapatali-kuchokera ku chemistry ya alloy melt kudzera pakuwunika komaliza. Ichi ndichifukwa chake malo athu amasunga magwiridwe antchito ogwirizana ndi ISO, makina, ndi metrology pansi padenga limodzi. Palibe ma handoffs. Palibe mipata ya mawonekedwe.

Kusankha Othandizira Anu a Stellite 21: Zosefera Zitatu Zosakambirana

Ngati ntchito yanu ikukhudza kukakamiza kopitilira 350 bar, kutentha kupitirira 400°C, kapena media abrasive media ndi> 15% solids content, dumphani mndandanda. Ikani zosefera izi m'malo mwake:

1. Kodi amasanthula mkati mwa OES ndi SEM-EDS? Ngati inde, funsani zitsanzo za malipoti owonetsa chizindikiritso cha gawo la carbide-osati kungoyambira chabe.
2. Kodi amatha kulemba zozungulira zochizira kutentha pa ASTM E290? Stellite 21 imafuna nthawi zonyowa zenizeni pa 1080°C ± 10°C. Kupatuka kwa ± 25 ° C kusuntha kwa carbide dissolution kinetics mosasinthika.
3. Kodi amasungabe kutsatiridwa kwazinthu zonse mpaka pazomwe zimasungunuka? Kufufuza kumaphatikizapo kusanthula kwa ladle, chipika choponyera, ndi mapu okhwima pambuyo pokonza - osati chiphaso chotsatira.

QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwiritsa ntchito zosefera zonse zitatu pagawo lililonse la stellite 21 lotumizidwa. Mzere wawo wopanga umaphatikiza AMS 5387-yogwirizana ndi cobalt alloy kusungunuka, kuyika ndalama molunjika, ma axis CNC contouring, ndi kutsimikizika kwa GD&T kochokera ku CMM-zonse zolembedwa ndi kutsata kwa digito. Sagulitsa magawo. Amapereka chidziwitso cha kuvala kwa moyo.

Lingaliro Lomaliza: Kusintha Ndi Mgwirizano Wantchito

A stellite 21 gawo si chodyedwa. Ndi mgwirizano wogwira ntchito wolembedwa mu cobalt, chromium, ndi tungsten. Ma micron aliwonse amayendedwe a carbide, mulingo uliwonse wa kuwongolera kwamafuta, ma decibel aliwonse azinthu zamakina ochepetsedwa ndi kugwedezeka. Sankhani othandizana nawo omwe amatengera m'malo ngati ukadaulo wazitsulo-osati mayendedwe.

Yang'anani m'tsogolo: njira zopangira makina osakanizidwa, kuneneratu kwa carbide morphology yoyendetsedwa ndi AI, ndi kutsimikizika kwamapasa a digito kumatanthawuza kudalirika kwazinthu zovala zapamwamba. Yambani ndi gawo loyenera la stellite 21-lero.
