Cubic boron nitride (CBN) sib tsoo log

CBN yog cov khoom siv tawv heev, thib ob rau pob zeb diamond, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua cov ntaub ntawv nyuaj xws li cemented carbide thiab high-speed steel.

CBN yog qhov ruaj khov ntawm qhov kub siab tshaj li pob zeb diamond, txhais tau hais tias thaum lub sij hawm kev kub ceev txiav los yog sib tsoo, CBN abrasive cuab yeej tsis yooj yim degraded.

Kev tuav lawv cov khoom txiav yog qhov tseem ceeb rau kev ua cov khoom nyuaj.

Ib leeg siv lead ua CBN tuaj yeem tswj tau qhov kev ua tau zoo ntawm qhov kub thiab txias, vim nws cov thermal stability. Txawm tias qhov kub thiab txias tsim thaum lub sij hawm sib tsoo high-speed tsis passivate nws. Tsis tas li ntawd, nws cov tshuaj tsis tshua muaj kev sib raug zoo rau cov hlau pawg hlau txhais tau tias tsis muaj adhesion thaum sib tsoo. Yog li, kev huv thiab kev sib tsoo efficiency ntawm cov cuab yeej sib tsoo yog tswj xyuas.

Txheej txheej tshuab ua haujlwm los ntawm kev ntxiv ib lossis ntau txheej ntawm cov khoom siv tshwj xeeb rau saum npoo ntawm CBN hais, xws li hlau, ceramics lossis lwm yam sib txuas los txhim kho lawv cov khoom.

Cov coatings no tsis tsuas yog tiv thaiv CBN cov khoom los ntawm kev hnav, tab sis kuj txhim kho lawv cov hnav tsis kam, tiv thaiv corrosion, thiab txawm tias kub tsis kam.
