Zakuthupi za Tungsten Carbide

Tungsten carbide, yomwe imadziwikanso kuti cemented carbide, ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito masiku ano. Zopanga za Tungsten carbide nthawi zonse zimakhala ndi kuuma kwakukulu, kukana kuvala, komanso mphamvu yabwino yoduka. Zambiri zakuthupi zimakhudzidwa ndi kuchuluka kwa cobalt ndi kaboni, kukula kwa tirigu, ndi porosity.

Kuchulukana

Kuchokera ku thupi, kachulukidwe wa zinthu za tungsten carbide ndi chiŵerengero cha misa yawo ndi voliyumu yawo. Kachulukidwe amatha kuyesedwa ndi kuwerengera bwino. Kuchulukana kwa tungsten carbide kumatha kukhudzidwa ndi misa ndi kuchuluka kwa tungsten carbide. Izi zikutanthauza kuti zonse zomwe zingakhudze misa kapena voliyumu zimatha kukhudzanso kachulukidwe.

Kuchuluka kwa iwo kungakhudze kachulukidwe wa tungsten carbide. Kachulukidwe ka cobalt ndi wamkulu kuposa kachulukidwe ka kaboni. Chifukwa chake cobalt ikachuluka mu tungsten carbide, kuchuluka kwa tungsten carbide kumakhala. M'malo mwake, carbon yambiri imakhala mu tungsten carbide, kutsika kwa tungsten carbide. Porosity ingakhudzenso kachulukidwe. Kuchuluka kwa porosity kumapangitsa kuti kachulukidwe kakang'ono.

Kuuma

Kuweruza kuuma kwa zinthu ndikofanana ndi kukana kwake kuvala. Chogulitsa cha tungsten carbide chokhala ndi kuuma kwambiri chimatha kupirira komanso kuvala bwino, kotero chimatha kugwira ntchito nthawi yayitali.

Monga bonder, cobalt yochepa imayambitsa kuuma bwino. Ndipo kutsika kwa kaboni kungapangitse tungsten carbide kukhala yovuta. Koma decarbonization imatha kupangitsa kuti tungsten carbide ikhale yosavuta kuwonongeka. Nthawi zambiri, tungsten carbide yabwino imawonjezera kuuma kwake.

Transverse kuphulika mphamvu

Mphamvu yodutsa modutsa ndikutha kwa tungsten carbide kukana kupindika. Tungsten carbide yokhala ndi mphamvu yodutsa bwino yoduka ndiyovuta kwambiri kuwonongeka ikakhudzidwa. Fine tungsten carbide ili ndi mphamvu yoduka bwino yodutsa. Ndipo particles za tungsten carbide zikagawanika mofanana, zopingasa zimakhala bwino, ndipo tungsten carbide sizovuta kuwononga.

Kupatula zinthu zitatu izi, pali zambiri zomwe tiyenera kudziwa, ndipo zimatha kuyesedwa ndi makina.

Ogwira ntchito yowunika zabwino nthawi zonse amawunika mawonekedwe azitsulo pansi pa maikulosikopu yazitsulo. Pamene cobalt yochulukirapo imayang'ana malo, imapanga dziwe la cobalt.

Titha kudziwa kuchuluka kwa cobalt poyesa maginito a cobalt ndi cobalt magnetic tester. Ndipo mphamvu yakumunda yokakamiza imathanso kuyesedwa ndi wokakamiza.

Kuchokera kuzinthu zakuthupi izi, zikuwonekeratu kuti tungsten carbide ili ndi katundu wambiri komanso ubwino wa migodi, wotopetsa, kudula, ndi kukumba.

Ngati mukufuna kudziwa zambiri ndi zambiri, mutha Lumikizanani Nafe kudzera nambala yafoni kapena imelo kumanzere, kapena Titumizireni Imelo pansi patsamba lino.
