stellite 21 inxalenye

Amalungu angama-21 eStellite ayasilela-hayi kuyilo olulambathayo, kodwa kwingcinga yokutshintsha engafanelekanga. Siye sabona iindibano ezintathu zempompo ye-hydraulic zithatha kwiiyure ezingama-48 zofakelo ngenxa yokutshintshwa stellite 21 inxalenye ifaniswe kuphela imilinganiselo eqhelekileyo, hayi uzinzo lwe-microstructure okanye ukuhanjiswa kwe-carbide. Ayiyompazamo yokwenza loo nto. Kukusilela kweenkqubo zemathiriyeli.

Kutheni le nto iStellite 21 iTshintsha ayingo “Tshintsha kwaye uhambe”

IStellite 21 yicobalt-chromium-tungsten alloy eqiniswe yi-eutectic carbides—M.₇C₃ kunye noM₂₃C₆-ezisa ukuxhathisa okugqithisileyo kwi-galling, abrasion, kunye ne-oxidation ephezulu yobushushu. Kodwa ukusebenza kwayo kuxhomekeke kwizinto ezine eziguquguqukayo ezingaxoxisiyo: izinga lokuqina ngexesha lokuphosa, umjikelo wokunyanga ubushushu obusemva kwe-weld, ukuqhubeka kwe-carbide kuwo wonke umphezulu wokunxitywa, kunye ne-interface ye-metallurgical bonding kwi-clad okanye ulungelelwaniso olungaphezulu.

Kusasazo lwehlabathi lokwenyani, siqhele ukwenza umlinganiselo wobunzima obungaphezulu kwe-120 HV kubunzulu obuyi-0.5 mm ekufakweni okusetyenzwe ngokungafanelekanga. Yiyo loo nto i-73% yokusilela kwangaphambi kwexesha sifumanisa ukuba ibuyela emva kwingcambu enye: inxalenye yatshintshwa ukusuka kwisitokhwe sebha esenziweyo endaweni yokuphosa okuqinileyo. Imathiriyeli esetyenzisiweyo ayinayo inethiwekhi ye-carbide elungelelanisiweyo efunekayo ukuze kugcinwe ukunyanzeliswa kwamasuntswana kwiimpompo ezinodaka okanye izihlalo zevalvu.

I-AMS 5387 ichaza ubuncinci be-carbide volume fraction (22-28%), umxholo we-chromium (27-31%), kunye noluhlu lwe-tungsten (3.5-5.5%). Nangona kunjalo ababoneleli abaninzi bathumela iinxalenye eziqinisekisiweyo kwi-AMS 5387 ngelixa behambisa i-chemistry yokwenene kwinqanaba eliphantsi lokunyamezela-i-chemically compliant, i-functional compromised. Siqinisekisa ibhetshi nganye nge-OES spectroscopy kunye necandelo elinqamlezayo lemephu ye-SEM-EDS ngaphambi kokukhululwa.

Iprothokholi eneNqanaba ezine eziNqanda iXabiso eliNcincisayo

Iinjineli zethu zentsimi ziye zaphuhlisa le migaqo emva kokuxhasa ngaphezulu kwe-142 yokutshintshwa kwezinto eziphezulu zokunxiba kwibala le-oyile, iiwintshi zehydraulic zaselwandle, kunye neempompo zepiston zemigodi. Isebenza ngenxa yokuba iphatha ukutshintshwa njengomsebenzi wokudibanisa inkqubo-hayi isiganeko sokuthengwa kwezixhobo.

• Inqanaba loku-1: uPhicotho lweNdibaniselwano — Ukulinganisa ubulukhuni besubstrate, uburhabaxa bomphezulu (Ra ≤ 0.8 µm), kunye neprofayili yoxinzelelo olushiyekileyo. Ukwaleka kweStellite 21 kuyacoleka ukuba ubulukhuni besubstrate bungaphezulu kwe-35 HRC ngaphandle kwe-interlayer nickel buffer.
• Inqanaba 2: Ukuqinisekiswa kweJometri -Qinisekisa i-radii ebalulekileyo, ii-angles ze-chamfer, kunye nokuthwala umphezulu othe tyaba usebenzisa ukulungelelanisa oomatshini bokulinganisa. Ukuphambuka kwe-0.015 mm kwi-radius yokuhlala kwandisa uxinzelelo loqhagamshelwano nge-40% kwiivalve zokunciphisa uxinzelelo.
• Inqanaba 3: Umdlalo weMetallurgical -Qinisekisa i-carbide morphology nge-metallografi. Ulwakhiwo olwamkelekileyo lubonisa i-M eqhubekayo, edityanisiweyo₇C₃ uthungelwano-kungekhona iziqithi ezizimeleyo okanye iidendrite eziqhekezayo.
• Inqanaba lesi-4: Ukutshiswa okusebenzayo -Baleka phantsi komthwalo olawulwayo imizuzu engama-30 kwi-60% yoxinzelelo oluphezulu olulinganisiweyo ngaphambi kokunyusa. Beka iliso ekunyukeni kobushushu kulo lonke ujongano; > 12°C imiqondiso yedelta ye-delta enganelanga ukudityaniswa kwe-thermal.

Xa iiCathalogu eziMgangatho zeCatalog ziwa Mfutshane-kunye nento omawuyenze endaweni yoko

Abanye banokuphikisa ukuba i-stellite engaphandle kwe-shelf 21 iinxalenye zinciphisa ixesha lokukhokela kunye neendleko. Nangona kunjalo, izinto ezisemgangathweni zekhathalogu azifane zihambelane nembali ye-thermal echanekileyo, i-carbide orientation, okanye indawo yenguqu ye-interface efunekayo kwi-mission-critical applications. Sithathe indawo ye-cobalt alloy nozzle engaphumelelanga kwimpompo yesitofu sekhemikhali ephezulu yoxinzelelo apho inxalenye ye-OEM yahlala iiyure ezingama-87. Eyokuqala etshintshileyo-efunyenwe kumthengisi wegeneric-yasilela kwiiyure ezili-19. Unobangela weengcambu? Ukwahlula kweCarbide kwincam ngenxa yokuqina okungafanelekanga kolwalathiso ngexesha lokuphosa.

Siyisombulule ngokutshintshela kwisisombululo se-custom-cast: utyalo-mali olujoliswe kwi-vertical mold orientation, kulandelwa ukuhlanganiswa kwe-HIP kunye nokuchaneka kwe-CNC evula iileyile ezininzi ze-axis. Inxalenye yokugqibela ihanjiswe iiyure ze-412 zexesha lokusebenza-4.7 × ubomi be-OEM. Izixhobo eziphambili: ulungelelwaniso lweenkozo olunxuseneyo ukuya kwicala lokuhamba, ukuqhubeka kwe-carbide okuqinisekiswe yi-micro-CT scanning, kunye nokugqitywa komphezulu okubanjwe kwi-Ra 0.2 µm kwindawo yokutywinwa.

Oku akuyothiyori. Iyaphinda-phinda. Kwaye ifuna ulawulo phezu kwekhonkco lexabiso elipheleleyo-ukusuka kwi-alloy ekrwada ye-melt chemistry ngokuhlolwa kokugqibela. Yiyo loo nto indawo yethu igcina i-ISO-ethobelayo imisebenzi yokuphosa, yomatshini, kunye ne-metrology phantsi kophahla olunye. Akukho handoffs. Akukho zithuba zojongano.

Ukukhetha iStellite Yakho 21 Icandelo leqabane: Iifilitha ezintathu ezingaxoxisiyo

Ukuba isicelo sakho sibandakanya uxinzelelo olungaphezulu kwe-350 bar, amaqondo obushushu angaphezu kwe-400 ° C, okanye i-media abrasive ene>15% yesiqulatho se-solids, yeqa uluhlu lokukhangela. Faka ezi zihluzo endaweni yoko:

1. Ngaba benza uhlalutyo lwe-OES kunye ne-SEM-EDS yangaphakathi? Ukuba ewe, cela iingxelo zeesampuli ezibonisa ukuchongwa kwesigaba se-carbide-kungekhona nje ukubunjwa kwe-elemental.
2. Ngaba banokubhala imijikelo yonyango lobushushu nge-ASTM E290 nganye? I-Stellite 21 ifuna amaxesha achanekileyo okufunxa kwi-1080°C ± 10°C. Izitenxo ze-±25°C shift carbide dissolution kinetics ngokungenakujikwa.
3. Ngaba bagcina umkhondo wemathiriyeli epheleleyo ukuya kwindawo yokuqala yokunyibilika? Ukulandeleka kubandakanya uhlalutyo lweladle, ilog yokuphosa, kunye nemephu yobulukhuni basemva komatshini-hayi nje isatifikethi sokuthotyelwa.

QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenzisa zonke izihluzi ezithathu kuzo zonke i-stellite 21 inxalenye yokuthunyelwa. Umgca wabo wokuvelisa udibanisa i-AMS 5387-ehambelanayo ne-cobalt alloy melting, i-vertical investment casting, i-five-axis CNC contouring, kunye ne-CMM-based based GD & T verification-konke kubhalwe ngokulandelelana okupheleleyo kwedijithali. Abathengisi iinxalenye. Bazisa uqikelelo lobomi bokunxiba.

Ingcamango yokuGqibela: Ukutshintshwa kweSivumelwano sokuSebenza

A stellite 21 inxalenye ayisiyonto ityiwayo. Yikhontrakthi yokusebenza ebhalwe kwi-cobalt, i-chromium, kunye ne-tungsten. Yonke i-micron yokulungelelaniswa kwe-carbide, lonke inqanaba lolawulo lobushushu, yonke i-decibel ye-vibration-dampened machine matters. Khetha amaqabane aphatha ukutshintshwa njengobunjineli besinyithi-hayi ulungiselelo.

Jonga phambili: iinkqubo ze-hybrid casting-machining, i-AI-driven carbide morphology prediction, kunye nokuqinisekiswa kwe-digital twin yeeprofayili zokunxiba kuya kuchaza isizukulwana esilandelayo sokuthembeka kwecandelo eliphezulu. Qala nge-stellite echanekileyo 21 inxalenye-namhlanje.
