Abubuwan da ke cikin jiki na suturar SiC suna nunawa a cikin yanayin juriya na zafin jiki, taurinsa, juriya na lalata da haɓakar thermal.

Matsalolin jiki na yau da kullun yawanci kamar haka:

Tauri: SiC shafi yawanci yana da Vickers Hardness a cikin kewayon 2000-2500 HV, wanda ke ba su matsanancin lalacewa da juriya a cikin aikace-aikacen masana'antu.

Yawan yawa: Rubutun SiC yawanci suna da nauyin 3.1-3.2 g/cm³. Babban yawa yana ba da gudummawa ga ƙarfin injina da dorewa na sutura.

Ƙarfafawar thermal: SiC coatings da high thermal conductivity, yawanci a cikin kewayon 120-200 W / mK (a 20 ° C). Wannan yana ba shi kyakkyawan yanayin zafi a cikin yanayin zafi mai zafi kuma ya sa ya dace da kayan aikin zafi na musamman a cikin masana'antar semiconductor.

Wurin narkewa: silicon carbide yana da wurin narkewa kamar 2730 ° C kuma yana da kyakkyawan kwanciyar hankali a yanayin zafi.

Coefficient na Thermal Expansion: SiC coatings da low mikakke coefficient na thermal fadada (CTE), yawanci a cikin kewayon 4.0-4.5 µm/mK (a cikin 25-1000 ℃). Wannan yana nufin cewa girman girmansa yana da kyau a kan manyan bambance-bambancen zafin jiki.

Juriya na lalata: SiC coatings ne musamman juriya ga lalata a cikin karfi acid, alkali da oxidizing yanayi, musamman a lokacin da yin amfani da karfi acid (kamar HF ko HCl), su lalata juriya nisa fiye da na al'ada karfe kayan.
