Borazon yog ib lub npe ntawm ib daim ntawv cubic ntawm boron nitride (cBN). Nws cov xim txawv los ntawm dub mus rau xim av thiab kub, nyob ntawm seb cov tshuaj lom neeg daim ntawv cog lus. … Borazon yog crystal tsim los ntawm cua sov sib npaug ntawm boron thiab nitrogen ntawm qhov kub siab tshaj 1800 ° C (3300 ° F) ntawm 7 GPa (1 lab lbf / hauv 2).
Puas CBN nyuaj dua pob zeb diamond?
CBN yog tsim los ntawm cubic boron nitride nplej sib koom ua ke los ntawm cov khoom siv ceramic. Nws nyuaj npaum li pob zeb diamond ntawm Mohs nplai, ua kom nws zoo rau cov ntaub ntawv ferrous hauv kev ua haujlwm lapping, vim nws yuav tsis carbonize thaum cuam tshuam nrog hlau (Fe), xws li pob zeb diamond abrasives.
Borazon sib tsoo log yog dab tsi?
A Borazon sib tsoo log yog tsim rau kev sib tsoo thiab ua kom zoo ntawm cov ntaub ntawv nyuaj. Lub log tuaj yeem siv tau ob qho tib si ntub thiab qhuav. Borazon siv lead ua yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws hauv ntiaj teb, sib tw txawm tias pob zeb diamond.
CBN abrasive yog dab tsi?
Cubic boron nitride (CBN) yog cov khoom siv zoo heev uas tsim los tshwj xeeb rau cov yam ntxwv hnav-tiv taus. … Qhov tseem ceeb, CBN abrasive nplej yog tsim los ntawm luv luv, covalent boron-nitrogen daim ntawv cog lus uas tsim nruj heev peb-dimensional (3D) matrices.
cubic boron nitride ua li cas?
Lub synthesis ntawm hexagonal boron nitride hmoov yog ua tiav los ntawm nitridation lossis ammonalysis ntawm boric oxide ntawm qhov kub siab. Cubic boron nitride yogtsim los ntawm siab siab, kev kho kub kub ntawm hexagonal BN. … h-BN tiv taus sintering thiab feem ntau yog tsim los ntawm kub nias.
