Tsananguro yeChigadzirwa
Kambani yedu inopa masevhisi ekugadzira SiC coating process neCVD method pamusoro pegraphite, ceramics nezvimwe zvinhu, kuitira kuti magasi akakosha ane kabhoni nesilicon aite pakupisa kwakanyanya kuti awane mamorekuru eSiC akachena, mamorekuru akaiswa pamusoro pezvinhu zvakaputirwa, zvichigadzira SIC protective layer.
Zvinhu zvikuru:
1. Kudzivirira kupisa kwakanyanya kwe oxidation:
Kusakwanisa kuoxidation kuchiri kwakanaka zvikuru kana tembiricha yakakwira kusvika 1600 C.
2. Kuchena kwakanyanya: kunogadzirwa nekuiswa kwemvura inodziya nemakemikari pasi pemamiriro ekupisa kwakanyanya.
3. Kuramba kukurwa kwevhu: kuomarara kwakanyanya, pamusoro pakaoma, zvidimbu zvitete.
4. Kuramba ngura: acid, alkali, munyu uye organic reagents.
