Cov nyhuv ntawm W cov ntsiab lus nyob rau hauv tungsten carbide siv lead ua tsev cog khoom theem ntawm lub zog flexural ntawm cov hlau

Khoov lub zog yog ib qho tseem ceeb ntawm lub cev khoom ntawm cemented carbide.Rau high-cobalt alloys, nws lub zog nce nrog qhov nce ntawm W cov ntsiab lus;thaum rau qis-cobalt alloys, qhov ntxeev yog qhov tseeb.

Qhov no yog vim hais tias tom qab cobalt theem ntawm lubhigh-cobalt alloyyog kev daws teeb meem muaj zog los ntawm W, cov yas deformation tsis kam ntawm cov hlau yog txhim kho, yog li ua kom lub zog;thaum lublow-cobalt alloyyog inherently brittle, thiab tom qab lub cobalt theem yog solid-solution ntxiv dag zog los ntawm W, lub zog yog txo.Alloy zog.

Kev sib raug zoo ntawm kev hnav tsis kam thiab W cov ntsiab lus yuav tsum tau piav qhia los ntawm kev ua tau zoo ntawm kev sib koom ua ke.Qhov siab dua W cov ntsiab lus, ntau cobalt muaj zog thiab siab dua qhov hnav tsis kam;cov alloy muaj me me ntawm eta theem uas tsis cuam tshuam qhov hnav tsis kam thaum siv.Txawm li cas los xij, thaum tus nqi ntawm eta theem yog loj, cov hlau yog nkig thiab ua rau chipping lossis tawg, ua rau kev puas tsuaj rau cov cuab yeej alloy.
