Qhov sib txawv tseem ceeb ntawm tungsten carbide thiab boron carbide yog tias boron carbide nyuaj thiab tawv dua li tungsten carbide.
Ob leeg tungsten carbide thiab boron carbide yog cov khoom tseem ceeb hauv kev lag luam uas nyuaj thiab tawv dua li cov hlau. Yog li ntawd, lawv muaj txiaj ntsig zoo hauv cov tshuab hnyav thiab hauv cov ntawv thov uas peb siv qhov cuam tshuam rau cov ntaub ntawv.
Tungsten Carbide yog dab tsi?
Tungsten carbide yog cov tshuaj sib xyaw uas muaj cov tshuaj formula WC. Tshwj xeeb, peb tuaj yeem hu nws yog carbide compound. Nws muaj qhov sib npaug ntawm tungsten thiab carbon atoms. Cov tshuaj no tshwm sim raws li cov hmoov zoo grey uas tuaj yeem nias thiab tsim ua cov duab los ntawm cov txheej txheem hu ua sintering. Tungsten carbide muaj txiaj ntsig zoo hauv kev lag luam machinery, txiav cov cuab yeej, abrasives, armour-piercing shells, thiab jewellery.
Qhov tseem ceeb tshaj, cov khoom no yog hais txog ob zaug tawv li hlau. Nws muaj tus nqi siab rau Young's modulus, uas tuaj yeem nyob ntawm 530 txog 700 GPa. Tsis tas li ntawd, qhov ntom ntawm cov khoom siv no yog ob npaug ntawm qhov ntom ntawm cov hlau. Qhov ntawd yog ze li ntawm nruab nrab ntawm qhov ntom ntawm cov hlau lead thiab kub. Ntxiv mus, peb tuaj yeem sib piv nws cov hardness nrog corundum vim nws cov hardness siab. Tungsten carbide tuaj yeem ua polishing thiab ua tiav tsuas yog nrog abrasives ntawm superior hardness, piv txwv li. cubic boron nitride thiab pob zeb diamond hmoov.
Peb tuaj yeem tsim tungsten carbide los ntawm cov tshuaj tiv thaiv ntawm tungsten hlau thiab carbon ntawm qhov kub thiab txias. Tsis tas li ntawd, peb tuaj yeem ua qhov no ntawm cov txheej txheem dej kub qis dua uas muaj cov tshuaj tiv thaiv ntawm tungsten hlau lossis tungsten oxide nrog cov pa roj carbon monoxide thiab carbon dioxide sib xyaw thiab hydrogen gas.
Muaj ob hom tungsten carbide li tungsten carbide thiab tungsten semi-carbide, nyob ntawm seb tus nqi ntawm carbide tam sim no ib qho sib npaug tungsten. Ob lub tebchaw no tuaj yeem pom nyob rau hauv cov txheej txheem, thiab qhov sib npaug ntawm tungsten thiab carbide nyob ntawm txoj kev txheej. Tsis tas li ntawd, cov khoom no decomposes ntawm qhov kub siab heev, tsim tungsten thiab carbon los ntawm cov txheej txheem thermal spray.
YBoron Carbide yog dab tsi?
Boron carbide yog cov tshuaj lom neeg muaj cov tshuaj formula B4C. Nws yog ib qho nyuaj heev boron-carbon ceramic khoom. Nws tseem yog covalent compound. Muaj ntau cov ntawv thov tseem ceeb ntawm cov khoom no, suav nrog kev siv hauv lub tank armour, cov tsho tiv thaiv cov mos txwv, lub cav sabotage hmoov, thiab ntau lwm yam kev siv. Nws zoo nkaus li grey tsaus lossis dub hmoov uas tsis muaj ntxhiab tsw. Nws yog insoluble hauv dej. Cov qauv siv lead ua yog rhombohedral.
Boron carbide yog cov khoom siv muaj zog nrog cov tawv tawv heev. Nws kuj tseem muaj qhov sib txawv siab rau kev nqus ntawm neutrons. Cov khoom no muaj kev ruaj ntseg rau ionizing hluav taws xob thiab feem ntau cov tshuaj lom neeg. Ntxiv mus, nws qhia cov khoom semiconductor ib yam nkaus.
Peb tuaj yeem tsim cov boron carbide los ntawm kev txo qis ntawm boron trioxide nyob rau hauv muaj cov pa roj carbon lossis magnesium ntawm lub qhov cub hluav taws xob. Ntawm no, yog tias peb siv cov pa roj carbon monoxide, cov tshuaj tiv thaiv yuav tshwm sim ntawm qhov kub siab tshaj qhov melting point ntawm boron carbide compound. Yog tias peb siv magnesium, cov tshuaj tiv thaiv yuav tshwm sim hauv graphite crucible, thiab peb tuaj yeem tshem tawm cov khoom siv los ntawm kev kho cov kua qaub.
Qhov txawv ntawm Tungsten Carbide thiab Boron Carbide yog dab tsi?
Tungsten carbide yog cov tshuaj sib xyaw uas muaj cov tshuaj formula WC thiab nws muaj qhov sib npaug ntawm tungsten thiab carbon atoms. Boron carbide yog ib qho nyuaj heev boron-carbon ceramic khoom uas muaj cov tshuaj formula B4C. Qhov sib txawv tseem ceeb ntawm tungsten carbide thiab boron carbide yog tias boron carbide nyuaj thiab tawv dua li tungsten carbide.
Cov hauv qab no nthuav tawm qhov sib txawv ntawm tungsten carbide thiab boron carbide hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Tungsten Carbide vs Boron Carbide
Ob leeg tungsten carbide thiab boron carbide yog cov khoom tseem ceeb hauv kev lag luam uas nyuaj thiab tawv dua li cov hlau. Qhov sib txawv tseem ceeb ntawm tungsten carbide thiab boron carbide yog tias boron carbide nyuaj thiab tawv dua li tungsten carbide.
