Lapho ipompo ye-hydraulic ihluleka endaweni yokugaya uwoyela engasogwini—noma i-winch shaft ibamba i-excavator yezimayini—umsuka awuvamile ukuklama. Kuyagqokwa. Futhi hhayi nje noma yikuphi ukugqokwa: i-micro-abrasion, i-galling, ukukhathala okushisayo ngaphansi kwemithwalo ye-cyclic engu-300°C. Kulapho Imboni ye-Stellite 6 izingxenye ikhono liyayeka ukuzikhethela. Iba umehluko phakathi kwamahora angu-8,000 esevisi kanye nokwehluleka kwenkundla okuyinhlekelele.
Senze imibhobho ye-Stellite 6 yamasistimu omjovo we-acid enomfutho ophezulu e-Saudi Arabia—futhi sawabuka edlula izizukulwane ezintathu zokushintshwa okujwayelekile kwe-stainless. Senze ngomshini izindlu zesilinda sepompo yepiston ye-AMS 5387 yama-OEM aseJalimane ayefuna ukuzungeza okungu-±0.015 mm ngobubanzi obungu-200 mm, nokuqedwa okungaphezulu kuka-Ra ≤0.4 µm ngemva kokugaya okokugcina. Lezi akuzona izicaciso zethiyori. Amabhentshimakhi ansuku zonke esikhungweni sethu se-ISO-certified foundry and machinening e-Qingdao.
I-Stellite 6 ayiyona nje enye ingxubevange ye-cobalt. Ukwakheka kwayo—cishe u-65% Co, 28% Cr, 4% W, plus Ni, Fe, kanye no-C—kudala i-matrix ye-chromium carbides eqinile eshumekwe kusixazululo esiqinile se-cobalt. Lokho kuyinikeza ukumelana okungenakuqhathaniswa ne-metal-to-metal galling, ukugqwala ezindaweni ezinothe nge-chloride, kanye nokuthamba okushisayo kufika ku-500°C. Kodwa nakhu abathengi abaningi abangakunaki: Ukukhipha i-Stellite 6 akufani nensimbi yokuphonsa. Indawo yayo yokuncibilika ephezulu (1,290–1,350°C), uketshezi oluphansi, kanye nokuncipha okudlulele kufuna isango elikhethekile, ukulawula ukushisa kwesikhunta okunembile, kanye nokwelashwa kokushisa kwe-post-cast homogenization. Yeqa noma isiphi isinyathelo—futhi uthola i-porosity, ukuhlukaniswa kwe-carbide, noma izigaba ze-brittle interdendritic. Sibone amakhasimende enqaba u-40% wokulingisa kwenqwaba yokuqala evela kubahlinzeki abangafanelekile. Isivuno sethu ekufakweni kwe-investimenti eyinkimbinkimbi ye-Stellite 6 sisebenza ku-92%+ ngoba silawula konke okuguquguqukayo: isitifiketi sempahla eluhlaza (wonke ama-cobalt base alloys e-T800-grade alandeleka emibikweni yokuhlolwa komshini), ukutholakala kwe-ingot encibilikisiwe, kanye nephrofayili yesikhathi sangempela esishisayo ngesikhathi sokuqina.
Ukuhlanganiswa okuqondile kwehlukanisa izimboni ezithembekile ze-Stellite 6 kubathengisi bempahla. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ukusakaza, ukwenziwa kwemishini kwe-CNC, nokuqeda kwenzeka ngaphansi kophahla olulodwa—nge-metrology eyabiwe, ukuhunyushwa okuhlanganisiwe kwe-GD&T, kanye nokulibaziseka okungekho emthethweni. Uma ikhasimende lithumela umdwebo wepulaki ye-cobalt alloy engajwayelekile enamashaneli okupholisa a-asymmetric kanye nokubekezelela indawo okungu-0.008 mm ezicini ezinezintambo ezinhlanu, asikukhiphi ukujika. Siyisebenzisa ku-5-axis DMG MORI NTX 1000 yethu, sisebenzisa amathuluzi anamathiphu e-PCD alungiselelwe ama-cobalt alloys, nge-laser eqhubekayo ehlola ukuze kuqinisekiswe ukujiya kodonga ngaphambi kokugaya i-ID yokugcina. Akekho umthengisi wangaphandle oqondayo ukuthi ingcindezi eyinsalela evela ekusakazeni ithinta kanjani ukuhlanekezelwa komshini kumzimba wevalvu ubude obungu-320 mm. Senza kanjalo—ngoba siyayiphonsa, siyayiphatha ngokushisa, siyimishini, futhi siyihlole ngohlelo olufanayo lwe-CMM kusukela ekuqaleni kuya ekugcineni.
Ukusebenza komhlaba wangempela kuncike ezintweni ezintathu okungaxoxiswana ngazo—hhayi izimangalo zokumaketha. Okokuqala: ukungaguquguquki kwezinto. Yonke indawo ye-Stellite 6 ihlaziywa nge-spectrographic, ukuqina kwemephu kuzo zonke izigaba, kanye nokuqinisekiswa kosayizi wokusanhlamvu kwe-ASTM E112. Okwesibili: ukwethembeka kobukhulu. Siqinisekisa izindawo ezibucayi sisebenzisa ama-optical profilometers—hhayi nje ama-CMM—ukubamba i-micro-topography ethinta ubuqotho bezimpawu. Okwesithathu: ukuqinisekiswa kokusebenza. Ngaphambi kokuthunyelwa, yonke i-valve yokucindezela idlula ukuhlolwa kwe-hydrostatic ku-1.5 × ingcindezi yokusebenza elinganiselwe; zonke izindlu zephampu zihlolwa ukuvuza nge-helium mass spectrometry. Amakhasimende aseNyakatho Melika naseYurophu awabuzi izitifiketi—acela imibiko yokuhlola eqondene nenqwaba enezitembu zesikhathi, ama-ID omsebenzisi, nezitembu zokulinganisa okokusebenza. Siyabahambisa.
Uma uhlelo lwakho lokusebenza lubandakanya ama-slurries abrasive, isitimu sezinga eliphezulu lokushisa, noma ukulayisha ngomjikelezo ongaphezu kuka-200 MPa, i-Stellite 6 ayibenzi bobunjiniyela ngokweqile. Kungumshwalense. Kodwa umshwalense usebenza kuphela uma umhlinzeki enesipiliyoni esiqinisekisiwe—hhayi nje izincwajana. Bheka impumelelo ebhalwe phansi emkhakheni wakho: ukuhlangana kwephampu kwezicelo ze-subsea, amarola e-winch center shaft for heavy-duty cranes, noma imibhobho ye-cobalt alloy yezitshalo zokukhipha usawoti emanzini. Hlola ukuthi banazo yini izimvume zenqubo ye-AMS 5387—hhayi nje izitifiketi zezinto ezibonakalayo. Qinisekisa ukuthi ingabe amarekhodi awo ekhwalithi ahlanganisa ukulandeleka okugcwele kuze kufike kunombolo yokushisa ye-cobalt ingot. Bese uqhathanisa isiyalo sokuletha: bangakwazi yini ukubamba amawindi ezinsuku ezingu-±3 kuma-oda evolumu emaphakathi ngaphandle kokusheshisa izinkokhelo? Lokho kuyisignesha yeqiniso Imboni ye-Stellite 6 izingxenye-hhayi isitolo somsebenzi esinemininingwane ye-cobalt alloy.
