Isingeniso:

Insimbi ye-Tungsten, eyaziwa nangokuthi i-cemented carbide, isho into eyinhlanganisela ene-sintered equkethe okungenani i-carbide eyodwa yensimbi. I-Tungsten carbide, i-cobalt carbide, i-niobium carbide, i-titanium carbide, ne-tantalum carbide yizingxenye ezivamile zensimbi ye-tungsten. Usayizi wokusanhlamvu wengxenye ye-carbide (noma isigaba) uvamise ukuba phakathi kwama-microns angu-0.2-10, futhi izinhlamvu ze-carbide zibanjwa ndawonye kusetshenziswa i-metallic binder. I-binder ngokuvamile ibhekisela ku-cobalt yensimbi (Co), kodwa kwezinye izinhlelo zokusebenza ezikhethekile, i-nickel (Ni), insimbi (Fe), noma ezinye izinsimbi nama-alloys nazo zingasetshenziswa. Inhlanganisela yokuhlanganisa ye-carbide nesigaba se-binder okumele inqunywe ibizwa ngokuthi "ibanga".

Ukuhlukaniswa kwensimbi ye-tungsten kwenziwa ngokuya ngamazinga we-ISO. Lokhu kuhlukaniswa kusekelwe ohlotsheni lwempahla yokusebenza (njengamamaki P, M, K, N, S, H). Ukwakheka kwesigaba se-binder kusetshenziswa kakhulu amandla ayo kanye nokumelana nokugqwala.

I-matrix yensimbi ye-tungsten iqukethe izingxenye ezimbili: ingxenye eyodwa yisigaba sokuqina; enye ingxenye iyinsimbi yokubopha. Izinsimbi zokuhlanganisa ngokuvamile ziyinsimbi yeqembu lensimbi, i-cobalt evame ukusetshenziswa kanye ne-nickel. Ngakho-ke, kukhona ama-alloys e-tungsten-cobalt, ama-tungsten-nickel alloys nama-tungsten-titanium-cobalt alloys.

Ezinsimbi eziqukethe i-tungsten, njengensimbi enesivinini esikhulu nezinye izinsimbi ezishisayo ezisebenza kanzima, okuqukethwe kwe-tungsten kunsimbi kungathuthukisa kakhulu ubulukhuni nokumelana nokushisa kwensimbi, kodwa ukuqina kuzokwehla kakhulu.

Ukusetshenziswa okuyinhloko kwezinsiza ze-tungsten nakho kuyi-carbide enosimende, okungukuthi, insimbi ye-tungsten. I-Carbide, eyaziwa ngokuthi amazinyo emboni yesimanje, isetshenziswa kabanzi emikhiqizweni yensimbi ye-tungsten.

Isakhiwo sesithako

Inqubo ye-sintering:

I-Sintering yensimbi ye-tungsten ukucindezela impushana ibe yi-billet, bese ufaka isithando somlilo ukuze sishise izinga lokushisa elithile (izinga lokushisa le-sintering), uyigcine isikhathi esithile (isikhathi sokubamba), bese uyipholisa phansi, ukuze uthole. impahla yensimbi ye-tungsten enezinto ezidingekayo.

Izigaba ezine eziyisisekelo zenqubo ye-tungsten steel sintering:

1. Esigabeni sokususa i-ejenti eyakhayo kanye ne-sintering yangaphambili, umzimba osiyishiwe wenza izinguquko ezilandelayo kulesi sigaba:

Ukususwa kwe-ejenti yokubumba, ngokukhuphuka kwezinga lokushisa esigabeni sokuqala sokuthungatha, i-ejenti yokubumba ibola kancane kancane noma ihwamuke, futhi umzimba owenziwe nge-sintered awufakiwe. Uhlobo, inani kanye nenqubo ye-sintering ihlukile.

Ama-oxide ebusweni bempushana ayancishiswa. Ezingeni lokushisa elishisayo, i-hydrogen inganciphisa ama-oxide e-cobalt ne-tungsten. Uma i-ejenti yokwakha ikhishwa ku-vacuum futhi ifakwe i-sintered, ukusabela kwe-carbon-oxygen akunamandla. Ukucindezeleka kokuxhumana phakathi kwezinhlayiya ze-powder kuqedwa kancane kancane, i-powder yensimbi ebophezelayo iqala ukubuyisela futhi ihlaziye kabusha, i-surface diffusion iqala ukwenzeka, futhi amandla e-briquetting ayathuthukiswa.

2. Isigaba esiqinile se-sintering (800℃——izinga lokushisa le-eutectic)

Ezingeni lokushisa ngaphambi kokuvela kwesigaba se-liquid, ngaphezu kokuqhubeka nenqubo yesigaba sangaphambilini, ukusabela kwesigaba esiqinile nokusabalalisa kuyaqiniswa, ukugeleza kwepulasitiki kuyathuthukiswa, futhi umzimba we-sintered uyancipha kakhulu.

3. Isigaba se-liquid sintering stage (izinga lokushisa eutectic - sintering temperature)

Lapho isigaba se-liquid sibonakala emzimbeni we-sintered, ukuncipha kuqedwa ngokushesha, kulandelwa ukuguqulwa kwe-crystallographic ukwakha isakhiwo esiyisisekelo kanye nesakhiwo se-alloy.

4. Isiteji sokupholisa (izinga lokushisa le-sintering - izinga lokushisa legumbi)

Kulesi sigaba, ukwakheka kanye nokwakheka kwesigaba sensimbi ye-tungsten kunezinguquko ezithile ezinezimo zokupholisa ezihlukene. Lesi sici singasetshenziswa ukushisisa insimbi ye-tungsten ukuze kuthuthukiswe izakhiwo zayo ezingokomzimba nezomshini.

Isingeniso sohlelo lokusebenza

Insimbi ye-Tungsten ingeye-carbide enosimende, eyaziwa nangokuthi i-tungsten-titanium alloy. Ubulukhuni bungafinyelela ku-89 ~ 95HRA. Ngenxa yalokhu, imikhiqizo yensimbi ye-tungsten (amawashi ensimbi e-tungsten avamile) akulula ukugqokwa, aqinile futhi angesabi ukukhishwa, kodwa aphuka.

Izingxenye eziyinhloko ze-carbide enosimende yi-tungsten carbide ne-cobalt, ehlanganisa amaphesenti angu-99 azo zonke izingxenye, futhi i-1% yizinye izinsimbi, ngakho-ke ibizwa nangokuthi i-tungsten steel.

Ivamise ukusetshenziswa ekwenzeni imishini enembayo ephezulu, izinto zamathuluzi ezinemba okuphezulu, amalebula, amabhithi okubhoboza okunomthelela, amabhithi okusika ingilazi, abasiki bamathayela, abaqinile futhi abakwesabi ukunemba, kodwa bayaphuka. Okwensimbi engavamile.

Insimbi ye-Tungsten (i-tungsten carbide) inochungechunge lwezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqoka, amandla amahle nokuqina, ukumelana nokushisa nokumelana nokugqwala, ikakhulukazi ubulukhuni bayo obuphezulu nokumelana nokugqoka, ngisho nasezingeni lokushisa elingu-500 ℃. Ihlala ingashintshile, futhi isenokuqina okuphezulu ku-1000 °C. I-Carbide isetshenziswa kabanzi njengento esetshenziswayo, njengamathuluzi okuguqula, abasiki bokugaya, amapulani, izinsimbi, amathuluzi ayisicefe, njll., ukusika insimbi, izinsimbi ezingezona ayoni, amapulasitiki, imicu yamakhemikhali, igraphite, ingilazi, itshe nensimbi evamile, futhi ingasetshenziselwa ukusika insimbi engazweli. Izinto zokwakha ezinzima emshinini njengensimbi eshisayo, insimbi engagqwali, insimbi ye-manganese ephezulu, insimbi yamathuluzi, njll. Isivinini sokusika se-carbide entsha enosimende siphindwe izikhathi ezingamakhulu kune-carbon steel.

Insimbi ye-Tungsten (i-tungsten carbide) ingase futhi isetshenziselwe ukwenza amathuluzi okumba amatshe, amathuluzi okumba, amathuluzi okumba, amathuluzi okulinganisa, izingxenye ezingagugi, ama-abrasives ensimbi, ama-cylinder linings, ama-precision bearings, imibhobho, njll.

Ukuqhathaniswa kwamabanga ensimbi ye-tungsten: S1, S2, S3, S4, S5, S25, M1, M2, H3, H2, H1, G1 G2 G5 G6 G7 D30 D40 K05 K10 K20 YG3X YG3 YG4C YG6 YG8 YG10 YG12 YL00 YL60 YG20 YG25 YG28YT5 YT14 YT15 P10 P20 M10 M20 M30 M40 V10 V20 V30 V40 Z01 Z10 Z20 Z30

Insimbi ye-Tungsten, imimese ye-carbide enosimende, kanye nokucaciswa okujwayelekile kwe-tungsten carbide kunohlu olukhulu, futhi izikhala ziyatholakala esitokweni.
