Hnav Resistance ntawm Silicon Carbide
1. Zoo hnav tsis kam: Vim tias cov yeeb nkab ceramic puas yog kab nrog corundum ceramics (lub Mohs hardness tuaj yeem ncav cuag 9.0 lossis ntau dua). Yog li ntawd, kev sib tsoo xov xwm thauj los ntawm metallurgical, hluav taws xob fais fab, mining, thee thiab lwm yam lag luam muaj siab hnav tsis kam. Nws tau raug pov thawj los ntawm indu ...Nyeem ntxiv -
Dab tsi yuav cuam tshuam rau pob tshab ntawm alumina ceramics?
Ib qho ntawm cov khoom tseem ceeb ntawm pob tshab ceramics yog nws cov transmittance. Thaum lub teeb dhau los ntawm qhov nruab nrab, lub teeb poob thiab kev siv zog attenuation yuav tshwm sim vim qhov nqus, qhov cuam tshuam ntawm qhov chaw, tawg thiab tawg ntawm qhov nruab nrab. Cov attenuations no nyob ntawm tsis yog tsuas yog nyob rau hauv cov tshuaj lom neeg ...Nyeem ntxiv -
Kev sib tw hauv kev lag luam ceramics intensifies ntsuab ib puag ncig tiv thaiv yog lub ntsiab qauv
Nrog rau kev txhim kho txuas ntxiv ntawm Tuam Tshoj txoj kev lag luam vaj tsev, tib neeg qhov kev thov rau ceramics kuj nce ntxiv, thiab Tuam Tshoj txoj kev lag luam ceramics kuj tau tsim sai heev. Raws li kev txheeb cais tsis tiav, nyob rau xyoo tas los no, tsuas yog lub nroog thiab cov nroog tau nqis peev ntau dua 300 billi ...Nyeem ntxiv
