Tungsten carbide, yomwe imadziwikanso kuti cemented carbide, ndi chinthu chamtengo wapatali chomwe ndi chofunikira kwambiri pakupanga zinthu zambiri. Njira zambiri zopangira zitsulo zimagwiritsa ntchito zoyikapo za tungsten carbide ngati nsonga za zida, popeza carbide yokhala ndi simenti imakhala ndi kuuma kwambiri komanso kukana kutentha kwabwino pobowola, wotopetsa, kupanga ndi kupanga zitsulo. Makina ambiri amakono a nkhope, zida za lathe ndi mphero zomaliza zimagwiritsa ntchito zida zodulira izi.

Kodi Tungsten Carbide Insert amapangidwa bwanji?
Mashopu opanga ndi opanga makina omwe amadalira zoyika za tungsten carbide pazida zothamanga kwambiri nthawi zambiri amadutsa masauzande ambiri chaka chilichonse. Ogwiritsa ntchito makina amagwira ntchito ndi zoyika zambiri tsiku lililonse, kudalira kuphatikiza kwawo kwa chemistry ndi geometry kuti apereke mbali zomwe zimafunikira pakulondola, kupanga mwachangu. Kumvetsetsa momwe ma carbide amapangidwira komanso momwe zopangira zopangirazo zimakhudzira kuthekera kwawo kungathandize ogwiritsa ntchito makina ndi opanga kumvetsetsa bwino zida zawo ndi njira zonse.

Kuyika kwa tungsten carbide kumakhala ndi simenti ya carbide, yomwe imapangidwa kuchokera ku cobalt ndi tungsten carbide. Tinthu tating'onoting'ono ta Tungsten carbide mkati mwa choyikapo chimapereka choyikapocho ndi mikhalidwe yake ya kuuma, ndipo cobalt imakhala ngati chomangira, kugwirizira zinthuzo molimba. Kukula kwa njere za tungsten zomwe zimagwiritsidwa ntchito kumakhudza kulimba kwa kuyika; Mbewu zazikulu (ma microns 3-5) zimabweretsa zofewa, zomangika mwachangu, pomwe timbewu tating'ono (zosakwana 1 micron) zimapangitsa kuti zikhale zolimba kwambiri, zosamva zoyika. Kuyika kolimba kwambiri, kumakhala kolimba kwambiri. Popanga zitsulo zolimba modabwitsa, zoyikapo zolimba zokhala ndi njere zing'onozing'ono nthawi zambiri zimagwiritsidwa ntchito, pomwe zoyikapo zofewa zimagwiritsidwa ntchito nthawi zambiri popanga makina okhala ndi mabala osokonekera, omwe amafuna kuti pakhale zolimba zochepa, zolimba. Chiŵerengero cha cobalt ndi tungsten carbide chimakhudzanso kuuma kwa ma carbide; cobalt ndi yofewa, kotero kuti cobalt ikalowa kwambiri, imakhala yofewa.

Katswiri wa Tungsten carbide insert atsimikiza kuti ndizovuta ziti zomwe ziyenera kukwaniritsidwa; njira yopangira imayamba ndi zopangira ufa. Tungsten yaufa, cobalt ndi kaboni amagayidwa ndikusakanizidwa ndi mowa ndi madzi, ndikupanga matope ambiri. Izi zimayikidwa mu chowumitsira, chomwe chimatulutsa madzi, ndikusiya ufa wosakanikirana bwino. Carbide amaika ndiye amadutsa sintering ndondomeko imene amasakanizidwa ndi polima kupanga phala, mbamuikha mu amafa oboola pakati ndi kuika mu ng'anjo yotentha kwambiri kuti sintered. Polima amasungunuka kuchokera pazoyikapo panthawiyi, ndipo zoyikapo zimachepa.

Zida zodulira za Tungsten carbide ndi zomata zosinthidwa za zida zodulira zomwe zimakhala ndi zida zenizeni. Zida zodulira zida zimaphatikizapo kutopetsa, kumanga, kudula ndi kugawa, kubowola, grooving, hobbing, mphero, migodi, kucheka, kumeta ndi kudula, kugogoda, ulusi, kutembenuza, ndi kutembenuza ma brake rotor.
