7 Izindlela Zokwehluleka Kwezinkinobho ze-Tungsten Carbide

Njengomkhiqizi wezinkinobho ze-tungsten carbide, sithole amakhasimende amaningi ehlushwa imibuzo mayelana nokwehluleka kwe-tungsten carbide. Le mibuzo ingabaukuguguleka, ukukhathala okushisayo, ukubhoboza, ukuqhekeka kwangaphakathi, ukuphuka kwezingxenye ezingavezwanga zenkinobho ye-carbide, ukuphuka kwe-shear, nokuqhekeka kwendawo. Ukuze sixazulule lezi zinkinga, kufanele sithole ukuthi yiziphi lezi zindlela zokuhluleka, futhi sibheke indawo lapho izinkinobho ze-carbide zonakaliswe kakhulu futhi zivame ukugqoka, izinkinobho ze-carbide ziphuka phezulu. Kulesi sihloko, sizokhuluma ngalezi zindlela ezi-7 zokwehluleka kanye neziphakamiso zokuzixazulula.

1. Ukugqokwa kwama-brasive

Kuyini ukugqokwa kwe-abrasive?

Ukuguga kwenzeka ngesikhathi sokungqubuzana nokungqubuzana phakathi kwezinkinobho namatshe e-tungsten carbide. Lena imodi yokwehluleka evamile futhi engenakugwenywa, ephinde ibe imodi yokugcina yokwehluleka kwezingcezu zokubhoboza. Ngokuvamile, ukugqokwa kwezinkinobho eziphakathi nezinkinobho zegeji kuhlukile. Izinkinobho ze-carbide, eziseduze konqenqema, noma ezinejubane eliphezulu lomugqa phakathi nomsebenzi, zizoba nokungqubuzana okukhulu okuhlobene nedwala, futhi ukugqokwa kungaba nzima kakhulu.

Iziphakamiso

Uma kukhona ukugqokwa kwe-abrasive kuphela, singathuthukisa ngokufanelekile ukumelana nokugqokwa kwezinkinobho ze-tungsten carbide. Singanciphisa inani lokuqukethwe kwe-cobalt noma sicwenge okusanhlamvu kwe-WC ukuze sifinyelele umgomo. Okufanele sikuqaphele ukuthi ukumelana nokugqoka kwezinkinobho ze-gauge kumele kube phezulu kunezinkinobho eziphakathi. Ukuqina okwenyukayo kungase kube okuphambene uma kukhona amanye amathuba okuhluleka.

2. Ukukhathala okushisayo

Kuyini ukukhathala okushisayo?

Ukukhathala okushisayo kubangelwa izinga lokushisa eliphezulu ngenxa yomthelela kanye nokungqubuzana phakathi kwamathiphu ezimayini ze-tungsten carbide, okungaba phezulu cishe ku-700°C. Ingabonwa kusukela ekubukeni kwezinkinobho ze-tungsten carbide lapho kunemifantu ephambanayo engazinzile ebusweni bamazinyo enkinobho. Ukukhathala okukhulu okushisayo kuzolimaza ngokuphelele izinkinobho ze-carbide zikasimende futhi kwenze i-drill bit iguge.

Iziphakamiso

1. Singanciphisa okuqukethwe kwe-cobalt ku-alloy ukuze sinciphise i-coefficient yokwandisa ukushisa kwezinkinobho ze-tungsten carbide;

2. Singakwazi ukwandisa usayizi wokusanhlamvu we-tungsten carbide powder ukwandisa ukuqhutshwa kwe-thermal ukuze izinga lokushisa eliphakeme elibangelwa ngesikhathi sokungqubuzana likhishwe ngesikhathi;

3. Singasebenzisa ukwakheka okungajwayelekile kokusanhlamvu kwe-WC ukuze siqinisekise ukumelana nokukhathala okushisayo, ukumelana nokugqoka, kanye nokuqina;

4. Singakwazi ukuklama kabusha ama-drill bits ukunciphisa indawo eveziwe yenkinobho;

3. Ukubhoboza

Yini i-spalling?

I-Spalling yigama elisetshenziselwa ukuchaza izindawo zikakhonkolo eziqhekekile futhi zancibilika ku-substrate. Embonini ye-carbide enosimende, ibhekisela kumodi yokwehluleka. Indawo yokuxhumana phakathi kwezinkinobho ze-carbide ezisikiwe kanye nedwala ingaphansi kwamandla angalingani, futhi imifantu yakheka ngaphansi kwesenzo esiphindaphindiwe sala mandla. Ukuqina kwengxubevange kuphansi kakhulu ukuvimbela ukuqhekeka ekukhuleni, okuholela ekusakazweni kwezinkinobho ze-tungsten carbide.

Kulezo zinkinobho ze-carbide ezinosimende ezinobulukhuni obuphakeme kanye nokuqina okuphansi, ukuqhuma okusobala kwenzeka, okuzonciphisa kakhulu impilo ye-drill bit. Usayizi we-spalling wezinkinobho ze-tungsten carbide uhlobene nokwakheka kwe-alloy, usayizi wokusanhlamvu we-WC, kanye nendlela yamahhala yesigaba se-cobalt.

Iziphakamiso

Isihluthulelo salolu daba ukuthi ungakhuphula kanjani ukuqina kwezinkinobho ze-carbide ezinosimende. Ekwenziweni, singathuthukisa ukuqina kwezinkinobho ze-carbide zikasimende ngokwandisa okuqukethwe kwe-cobalt ye-alloy nokucwenga okusanhlamvu kwe-WC.

4. Imifantu yangaphakathi

Iyini imifantu yangaphakathi?

Imifantu yangaphakathi iyimifantu evela esakhiweni sangaphakathi se-tungstenizinkinobho ze-carbide, ezaziwa nangokuthi ukwehluleka okubulalayo kwangaphambi kwesikhathi. Kunezingxenye ezibushelelezi, ezibuye zibizwe ngokuthi izingxenye zesibuko, nezingxenye eziqinile, ezibizwa nangokuthi izingxenye ze-jaggies, endaweni ephukile. Umthombo wokuqhekeka ungatholakala engxenyeni yesibuko.

Iziphakamiso

Njengoba ukuqhekeka kwangaphakathi kubangelwa ikakhulukazi izinkinobho ze-carbide ezihlanganisiwe ngokwazo, indlela yokugwema ukuqhekeka kwangaphakathi ukuthuthukisa ikhwalithi yezinkinobho ze-tungsten carbide ngokwabo. Singakwazi ukuzivumelanisa ne-pressure sintering, kanye nokucindezela okushisayo kwe-isostatic nokwelashwa kokushisa ngemva kokucwilisa.

5. Ukuphuka kwezingxenye ezingavezwanga

Kuyini ukuphuka kwezingxenye ezingavezwanga?

Lapho senza izinkinobho ze-tungsten carbide ngendlela engafanele, ukuphuka kwezingxenye ezingavezwanga kuzokwenzeka. Futhi kungase kubangelwe ukucindezelwa okukhulu kwengcindezi evela kusimo esingaphandle kwendingilizi sembobo yegiya engaguquki kanye nezinyo lebhola okubangela ingcindezi ukuthi igxile endaweni ethile emzimbeni wenkinobho. Ngokuqhekeka okwenzeka lapho imbobo ingajulile, imifantu izosabalala kancane kancane ngokugoba kancane, futhi ekugcineni, yakha indawo ebushelelezi. Ngokuqhekeka okuvela engxenyeni ejulile yembobo yamabhithi okubhoboza, ukuqhekeka kuzobangela ingxenye engenhla yenkinobho ukuthi ihlukane ngobude.

Iziphakamiso

1. Qinisekisa ukuthi amazinyo ebhola abushelelezi ngemva kokugaya, akukho ngaphandle kwendilinga, akukho mifantu yokugaya;

2. phansi kwembobo yezinyo kufanele kube nesimo sokusekela esifanele esivumelana nendawo engezansi yenkinobho;

3. khetha ububanzi bezinyo obufanele kanye nobubanzi bembobo lapho ucindezela okubandayo noma ushumeka kushisa Inani elihambisanayo.

6. Ukuphuka kwe-shear

Kuyini ukuphuka kwe-shear?

Ukuphuka kwe-shear kusho ukuphuka kanye/noma ukuhlakazeka kwento ngenxa yokusetshenziswa kwamandla obunzima endaweni yayo. Ukuphuka kwe-shear kwe-tungsten carbide kuwumphumela wezinkinobho ze-tungsten carbide ezihlale zivezwa ekucindezelekeni okucindezelwayo kanye ne-shear ngaphezu kwemingcele i-tungsten carbide engakwazi ukumelana nayo. Ngokuvamile, ukuphuka kwe-shear akulula ukutholakala, futhi kusengasebenza ngemva kokuba khona ukuphuka. Ukuphuka kwe-shear kuvame ukubonakala ekugcineni kweshizolo.

Iziphakamiso

Ukunciphisa amathuba okuphuka kwe-shear, singazungeza izinkinobho ze-carbide zikasimende, futhi siklame futhi sikhethe ukwakheka kwebhithi lokubhola elifanele.

7. Ukuqhekeka kobuso

Iyini imifantu engaphezulu?

Ukuqhekeka komhlaba kukhiqizwa ngemuva kokulayisha imvamisa ephezulu nezinye izindlela zokwehluleka. Imifantu emincane ebusweni izokhula kancane kancane. Kubangelwa ifomu lesakhiwo, indlela yokubhoboza izingcezu zokubhoboza, ukuma kwamazinyo enkinobho ye-tungsten carbide, kanye nesakhiwo setshe okufanele sibhojwe.

Iziphakamiso

Singakwazi ukunciphisa okuqukethwe kwe-cobalt ebusweni ukwandisa ubulukhuni futhi sithuthukise ukuqina kwezinkinobho zezimayini ze-tungsten carbide.

Ukulandela izindlela zokuhluleka nokusikisela, ungaqhubeka uqonda ukuthi kungani izinkinobho zakho ze-tungsten carbide zihluleka emsebenzini. Ngezinye izikhathi, ungase uthole ukuthi kunzima ukuthola ukuthi iyiphi inkinga eyinhloko mayelana nezinkinobho zakho ze-tungsten carbide, nakuba ujwayelene nazo zonke izinhlobo zemodi yokwehluleka ngoba akukhona okukodwa okuyimbangela enengqondo.

Njengomkhiqizi wezinkinobho ze-tungsten carbide, indlela yokuxazulula izinkinga zamakhasimende mayelana nokugqoka kwe-tungsten carbide kuyimpendulo yethu. Sizohlaziya amacala, sithole inkinga, futhi sinikeze amakhasimende ethu isisombululo esingcono.
