Izinto ezijwayelekile zamathuluzi e-carbide aqinisiwe zihlanganisa kakhulu i-carbide eqinisiwe esekelwe ku-tungsten carbide, i-carbide eqinisiwe esekelwe ku-TiC(N), i-carbide eqinisiwe ene-TaC (NbC eyengeziwe), kanye ne-carbide eqinisiwe kakhulu. Ukusebenza kwezinto ze-carbide eziqinisiwe kunqunywa kakhulu yizigaba zokuqinisa ezengeziwe.
I-Carbide Eqinisiwe Ene-TaC Eyengeziwe (i-NbC)
Ukwengeza i-TaC (NbC) ku-carbide eqinisiwe kuyindlela ephumelelayo yokuthuthukisa ukusebenza kwayo. Kuma-alloy e-TiC/Ni/Mo, ukufaka esikhundleni ingxenye ye-TiC ngama-carbide afana ne-WC ne-TaC, anikeza ukuqina okungcono, kuthuthukisa ukusebenza kwe-carbide eqinisiwe futhi kwandise ububanzi bokusetshenziswa kwayo. Ukwengezwa kwe-WC ne-TaC kuthuthukisa:
● Ukuqina
● I-modulus enwebekayo
● Ukumelana nokuguqulwa kwepulasitiki
● Amandla okushisa aphezulu
Futhi kuthuthukisa ukuhanjiswa kokushisa kanye nokumelana nokushaqeka kokushisa, okwenza ithuluzi lifaneleke kakhulu ekusikeni okuphazamisekile. Kuma-alloy e-WC-Co, ukusebenza kungathuthukiswa ngokungeza u-0.5% kuya ku-3% (ingxenye yesisindo) sama-carbide njenge-TaC, i-NbC, i-Cr3C2, i-VC, i-TiC, noma i-HfC. Izinhloso eziyinhloko zifaka:
● Ukuhluzwa kokusanhlamvu
● Ukugcina isakhiwo sekristalu esifanayo ngaphandle kokuphinda kusetshenziswe kabusha
● Ukwandisa ubulukhuni nokumelana nokuguguleka ngaphandle kokubeka engcupheni ukuqina
Ngaphezu kwalokho, lezi zithasiselo ziyasiza:
● Ubulukhuni obuphezulu bokushisa
● Amandla okushisa aphezulu
● Ukumelana ne-oxidation
Ngesikhathi sokusika, kwakheka ifilimu ye-oxide eqinile, ezikhokhelayo, emelana nokuguguleka okunamathelayo kanye nokusabalala lapho kulungiswa izinsimbi noma ama-alloy athile. Lokhu kuthuthukisa ukumelana nokuguguleka kwethuluzi futhi kwandisa ikhono lalo lokumelana nokuguguleka kwe-crater kanye nokuguguleka kwe-flank. Lezi zinzuzo ziba sobala kakhulu njengoba okuqukethwe yi-cobalt ku-carbide eqinisiwe kukhuphuka.
● I-carbide efakwe usimende ene-1% kuya ku-3% (ingxenye yesisindo) i-TaC (NbC) ingasebenzisa izinsimbi ezahlukahlukene ezihlanganisiwe, okuhlanganisa insimbi eqinile kakhulu kanye nensimbi ehlanganisiwe.
● Ama-alloy e-cobalt aphansi ane-3% kuya ku-10% (ingxenye enkulu) i-TaC (NbC), njenge-YG6A, YG8N, kanye ne-YG813, ayasebenziseka ngezindlela eziningi. Angacubungula:
Insimbi ephothiwe ebandayo
Insimbi ephonswe nge-ductile
Izinsimbi ezingezona i-ferrous
Izinto ezilukhuni ukushintshwa njengomshini wensimbi engagqwali, insimbi eqinile, kanye nezinsimbi ezisebenza ngokushisa okuphezulu
Lezi zaziwa kakhulu ngokuthi ama-alloy ajwayelekile (YW). Ukwandisa okuqukethwe kwe-cobalt kukhulisa amandla nokuqina kwalolu hlobo lwe-carbide oluqinisiwe, okwenza lufanelekele ukwenziwa ngomshini onzima kanye nokusikwa okuphazamisekile kwezinto ezilukhuni ukukwenziwa emshinini. Izicelo zifaka:
● Ukuhlikihla izinsimbi ezinkulu ezibunjiweyo nezingcwecwe
● Ukujika, ukuphotha, nokugaya insimbi ye-austenitic kanye ne-alloys engashisi
● Umshini wokusika ngama-engeli amakhulu erekhi, izingxenye ezinkulu zokusika, kanye nesivinini esiphakathi kuya kwesiphansi
● Ukuvula ngokungemthetho ama-lathe azenzakalelayo, azenzakalelayo, kanye namathuluzi amaningi
● Ukukhiqiza imishini yokubhoboza, ama-gear hobs, namanye amathuluzi anamandla aphezulu okusebenza**
Kuma-alloy e-WC-TiC-Co, okuqukethwe kwe-TiC ngokweqile kwandisa ukuzwela ekuqhekekeni kokushisa, okuholela ekuqhekekeni okukhulu. Ukwengeza i-TaC kuma-alloy e-WC-Ti-Co ane-cobalt ephansi, kuyathuthuka:
● Ukuqina
● Ukumelana nokushisa
● Ukumelana ne-oxidation
Nakuba i-TiC yehlisa ukumelana nokushaqeka kokushisa, i-TaC iyayikhokhela lokhu, okwenza i-alloy ifaneleke ukusebenza kokugaya. Ezinye izindlela ezingabizi kakhulu njenge-NbC noma i-Hf-Nb carbides (ingxenye enkulu: Hf-60%, Nb-40%) ingathatha indawo ye-TaC. Kuma-alloy e-TiC-Ni-Mo, ukwengeza i-TiN, i-WC, kanye ne-TaC ngesikhathi esisodwa kuthuthukisa kakhulu:
● Ukuqina
● Amandla okugobeka
● Ukumelana ne-oxidation
● Ukushisa okusebenzayo
emazingeni okushisa aphezulu (900–1000°C).
I-Carbide Ene-Cemented Ene-Ultrafine Grain
Ukucwenga izinhlamvu ze-carbide esimende kunciphisa usayizi wesigaba esiqinile, kwandisa indawo engaphezulu kwezinhlayiya zesigaba esiqinile kanye namandla okubopha phakathi kwezinhlayiya. Isigaba sokubopha sisabalala ngokulinganayo nxazonke zazo, sithuthukisa:
Ubulukhuni
Ukumelana nokugqoka
Ukwandisa okuqukethwe kwe-cobalt ngendlela efanele kukhulisa amandla okuguquguquka. I-carbide eyenziwe nge-cemented e-ultrafine, eyakhiwe yizinhlayiya ezincane kakhulu ze-WC ne-Co, ihlanganisa:

Ubulukhuni: 90–93 HRA
Amandla okugobeka: 2000–3500 MPa
Amabanga akhiqizwa eShayina afaka phakathi i-YS2 (YG10H, YG10HT), i-YM051 (YH1), i-YM052 (YH2), i-YM053 (YH3), i-YD05 (YC09), i-YD10 (YG1101), i-B60, i-YG610, i-YG643, kanye ne-YD05. Ngenxa yokusanhlamvu kwayo okuhle kakhulu, i-carbide efakwe ucezu oluqinile ingagaywa ibe yimiphetho yokusika ebukhali kakhulu enobukhulu obuphansi bomphezulu, okwenza ibe yindawo efaneleke kakhulu kumathuluzi okunemba afana nalawa:
Ama-Broaches
AmaReamers
Ama-hob aqondile
Ihamba phambili ekushiseni ngobubanzi obuncane bokusika kanye nezinga lokuphakela. Ifanele futhi amathuluzi amancane afana nalawa:

Imibuzo evamile yamakhasimende kanye nezimpendulo ze-Huaxin
Lokho kuncike enanini, ngokuvamile izinsuku ezi-5-14. Njengomkhiqizi wezinsika zezimboni, i-Huaxin Cement Carbide ihlela ukukhiqizwa ngama-oda kanye nezicelo zamakhasimende.
Ngokuvamile amasonto ama-3-6, uma ucela imimese yomshini eyenziwe ngokwezifiso noma ama-blade ezimboni angekho esitokweni ngesikhathi sokuthenga. Thola i-Sollex Purchase & Delivery Conditions lapha.
uma ucela imimese yomshini eyenziwe ngokwezifiso noma ama-blade ezimboni angekho esitokweni ngesikhathi sokuthenga. Thola Izimo Zokuthenga Nokulethwa ze-Sollexlapha.
Ngokuvamile i-T/T, i-Western Union...idiphozithi kuqala, Wonke ama-oda okuqala avela kumakhasimende amasha akhokhelwa kusengaphambili. Ama-oda engeziwe angakhokhwa nge-invoyisi...Xhumana nathiukwazi okwengeziwe
Yebo, xhumana nathi, imimese yezimboni iyatholakala ngezindlela ezahlukene, kufaka phakathi imimese enesitsha esiphezulu, imimese eyindilinga engezansi, imimese enezinyo ezigobile/ezinamazinyo, imimese ebhoboza nxazonke, imimese eqondile, imimese ye-guillotine, imimese ecijile, imimese ye-razor engunxande, kanye nemimese ye-trapezoidal.
Ukuze sikusize uthole i-blade engcono kakhulu, i-Huaxin Cement Carbide ingakunikeza ama-blade amaningana amasampula ongawahlola ekukhiqizweni. Ukuze usike futhi uguqule izinto eziguquguqukayo njengefilimu yepulasitiki, i-foil, i-vinyl, iphepha, nokunye, sinikeza ama-blade okuguqula kufaka phakathi ama-slitter blade anezikhala kanye nama-razor blade anezikhala ezintathu. Sithumelele umbuzo uma unentshisekelo kuma-blade omshini, futhi sizokunikeza isipho. Amasampula emimese eyenziwe ngokwezifiso awatholakali kodwa wamukelekile uku-oda inani elincane kakhulu le-oda.
Kunezindlela eziningi ezizokwandisa isikhathi eside kanye nokuphila kweshelufu kwemimese yakho yezimboni kanye nama-blade esitokweni. Xhumana nathi ukuze wazi ukuthi ukupakishwa okufanele kwemimese yomshini, izimo zokugcina, umswakama kanye nokushisa komoya, kanye nokwembozwa okwengeziwe kuzovikela imimese yakho futhi kugcine ukusebenza kwayo kokusika.
