Pfeka! Chii? --- Mhando dzeTungsten Carbide Wear

Tungsten carbide ndechimwe chezvinhu zvakajairika mumatombo ekudhira mabheti. Iine zvimiro zvekugadzikana kwakanaka kwekushisa, kuoma, uye nzvimbo yakakwira yekunyungudika, tungsten carbide inogona kuiswa mumamiriro mazhinji nekupisa kwakanyanya uye kukanganisa. Tungsten carbide zvigadzirwa zvinogadzirwa kubva tungsten carbide poda uye binder chikamu, kazhinji cobalt. Iyo binder phase, cobalt, inogona kuwedzerwa kuwedzera kuoma kwechibhorani. Kunyange zvazvo tungsten carbide ichizivikanwa seimwe yezvinhu zvakaoma zvikuru munyika, inogona kukuvadzwa kana ikashandiswa nenzira isiri iyo kana kushandiswa kwenguva yakareba. Zvipfeko zvinonyanya kukamurwa kuita marudzi matatu: abrasive kupfeka, anonamira kupfeka, uye erosive kupfeka.

Abrasive kupfeka

Kana tungsten carbide chigadzirwa chikashandiswa kugadzira kana kucheka zvimwe zvinhu zvakaomarara, abrasive kupfeka kunogona kuitika. Izvo zvakanyanya kuoma tungsten carbide zvigadzirwa, zvakanyanya kuoma kuve neabrasive kupfeka. Abrasive kupfeka inogona kuiswa mumhando mbiri, maviri-muviri abrasion, uye matatu-muviri abrasion. Miviri-yemuviri abrasion system inosanganisira tungsten carbide zvigadzirwa uye workpiece ichagadzirwa. Muhurongwa hwekukweshwa kwemuviri-mitatu, imwe yemitumbi ndiyo zvidimbu zvakagadzirwa panguva yekukwenya uye kugaya pakati pemimwe miviri miviri. Kupfeka kweabrasive hakungosiyi chete kupfeka kuri pachena pamusoro pezvigadzirwa zve tungsten carbide asiwo kunokonzeresa kuneta pasi peiyo tungsten carbide zvigadzirwa, izvo zvinogona kuwedzera mukana wekukuvadza mune ramangwana.

Adhesive kupfeka

Kupfeka kunonamira kunoitika kana zvinhu zviviri zvichikweshana pamwe nesimba rakakwana kuti zvikonzere kubviswa kwezvinhu kubva panzvimbo isingapfeki. Kupfeka kunonamira kunoitika pane tungsten carbide cutters kana pakati petungsten carbide nemabhiti ekuboora. Chikonzero chikuru chetungsten carbide mabhatani iko kushandiswa kusiri iko kwetungsten carbide mabhatani kana kukanganisa kunopfuura izvo tungsten carbide inogona kutsungirira.

Erosive kupfeka

Muchokwadi, kune imwe mhando yekupfeka tungsten carbide inonzi erosive wear. Erosive wear inzira yekufambira mberi yekubvisa zvinhu kubva panzvimbo inotarirwa nekuda kwekudzokororwa kudzokororwa kwezvimedu zvakasimba. Yepamusoro-mhando tungsten carbide ine yakanaka erosion kupfeka kuramba, saka hazviwanzo kuitika.

Tungsten carbide ndiyo yakanyanya kuoma zvinhu zvishoma pane dhaimani asi inogona zvakare kukuvara. Kuti uderedze mukana wekukuvara, zviri nani kuishandisa muhukuru hwakakodzera uye mune yakakodzera mamiriro.

Kana iwe uchifarira tungsten carbide rods uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
