I-carbide enosimende, "njengamazinyo embonini", iyinto ebaluleke kakhulu kumathuluzi esimanje. Ukusetshenziswa kwayo kuya ngokuya kusabalele, futhi kuthandwa kakhulu emikhakheni eminingi efana nowoyela negesi, izimayini zamalahle, ukulawula uketshezi, imishini yokwakha, i-aerospace nokunye. Ngakho-ke, ungasebenzisa kanjani izinsiza ezilinganiselwe ukuthuthukisa ukusebenza kahle? Lokhu kudinga ukuthuthukisa ukusebenza kwe-carbide enosimende ukuze kuthuthukiswe impilo yesevisi nokusebenza kahle komsebenzi.

1.Thuthukisa ikhwalithi yezinto ezingavuthiwe.

A.Thuthukisa ukuhlanzeka kwezinto zokusetshenziswa

Kukholakala ukuthi ukulandelela izakhi ezifana ne-Na, Li, B, F, Al, P, K nezinye izinto zokulandela umkhondo ezinokuqukethwe okungaphansi kuka-200PPm zinamazinga ahlukahlukene ethonya ekwehlisweni, i-carbonization kanye ne-sintering ye-carbide enosimende ye-N powder, Futhi umthelela ezakhiweni nesakhiwo sengxubevange nakho kuwufanele ukufundwa.Isibonelo, ama-alloys anamandla aphezulu kanye nokuqina komthelela omkhulu (njengama-alloys ezimayini namathuluzi okugaya) anezidingo eziphezulu, kuyilapho ama-alloys amathuluzi okusika aqhubekayo anomthwalo ophansi kodwa ophezulu. ukunemba machining akudingi high impahla eluhlaza ubumsulwa.

B.Lawula usayizi wezinhlayiyana nokusatshalaliswa kwezinto ezingavuthiwe

Gwema izinhlayiya ezinkulu kakhulu ku-carbide noma ku-cobalt powder izinto zokusetshenziswa, futhi uvimbele ukwakheka kwezinhlamvu ze-carbide ezimahhadla namachibi e-cobalt lapho i-alloy is sintered.

Ngesikhathi esifanayo, usayizi wezinhlayiyana kanye nosayizi wezinhlayiyana ukwakheka kwezinto zokusetshenziswa kulawulwa ukuze kuhlangatshezwane nezidingo zemikhiqizo ehlukene. Isibonelo, amathuluzi okusika kufanele asebenzise i-tungsten carbide powder enosayizi wezinhlayiyana ze-Fisher ngaphansi kwama-microns angu-2, amathuluzi angagugi kufanele asebenzise u-2-3 microns we-tungsten carbide powder, futhi amathuluzi ezimayini kufanele asebenzise i-tungsten carbide powder enkulu kuno-3 microns.

2. Thuthukisa i-microstructure ye-alloy.

I-Ultrafine Grain Alloy

Usayizi wokusanhlamvu we-carbide ungaphansi kwe-1μm, futhi ungaba nobulukhuni obuphezulu kanye nokuqina ngesikhathi esifanayo.

I-Heterogeneous Structural Alloys

I-Heterogeneous structure alloy iwuhlobo olukhethekile lwe-carbide enosimende ene-microstructure engalingani noma ukwakheka, okwenziwa ngokuxuba izinhlobo ezimbili zezingxube ezinezingxenye ezihlukene noma osayizi bezinhlayiyana ezihlukene. Ivamise ukuba nokuqina okuphezulu kwama-alloys anama-coarse-grained kanye nokumelana nokugqoka okuphezulu kwama-alloys anezinhlamvu ezinhle, noma kokubili ukuqina okuphezulu kwama-alloys e-cobalt aphezulu kanye nokumelana nokugqoka okuphezulu kwama-alloys e-cobalt aphansi.

I-Superstructural Alloys

Ngenqubo ekhethekile yokukhiqiza, ukwakheka kwengxubevange yakhiwe izifunda eziqondiswe ku-anisotropic tungsten carbide single crystal flake ezixhunywe emithanjeni yensimbi enothe nge-cobalt. Le alloy inokumelana nokugqokwa okuvelele kanye nokuqina okuphezulu kakhulu uma ingaphansi kokushaqeka kokucindezela okuphindaphindiwe.

I-Gradient Alloy

Ama-alloys anezinguquko ze-gradient ekwakhiweni kwawo aholela ekushintsheni kokukhula kokuqina nokuqina.

3. Thuthukisa noma khetha isigaba esisha esiqinile nesigaba sokubopha.

4. Ukwelashwa kokuqina kobuso.

Xazulula ukungqubuzana phakathi kokumelana nokugqokwa kanye nokuqina, ubulukhuni namandla e-carbide enosimende.

Ukugqoka:Dbeka ungqimba lwe-TiC noma lwe-TiN phezu kwe-alloy eqinile enokuqina okungcono ngezindlela ezibonakalayo noma zamakhemikhali ukuze kwandiswe ukumelana nokuguga kwengxubevange.

Njengamanje, ukuthuthukiswa okusheshayo kwe-boronizing, i-nitriding, kanye ne-electric spark deposition yi-carbide enosimende eboshwe.

5. Ukwengeza izakhi noma izinhlanganisela.

6. Ukwelashwa kokushisa kwe-carbide enosimende.
