I. Nhanganyaya yegirazi kabhoni chimiro
Hunhu:
(1) Pamusoro pegirazi kabhoni inotsvedzerera uye ine chimiro chegirazi;
(2) Girazi kabhoni ine kuoma kwakanyanya uye yakaderera guruva chizvarwa;
(3) Girazi kabhoni ine yakakura ID / IG kukosha uye yakaderera kwazvo dhigirii yegraphitization, uye yayo yekupisa kupisa kuita kuri nani;
(4) Girazi kabhoni yakaoma-ku-graphitize kabhoni ine yakanaka yakakwirira tembiricha kuramba uye kugadzikana kwakasimba pakupisa kwepamusoro;
(5) Girazi kabhoni ine diki rekuita pamusoro penzvimbo uye yakanakisa kemikari corrosion resistance, uye inoshingirira kukukurwa neokisijeni, silicon, nezvimwe.
II. Nhanganyaya kune girazi kabhoni coating
Iyo yekumusoro pores yeflake graphite coating inogoverwa uye chimiro chakasununguka, nepo chimiro chegirazi kabhoni coating chakasimba uye hachidonha!
1. Anti-oxidation kuita kwegirazi kabhoni coating
(1)Laminated yakaoma kunzwa
Girazi kabhoni yekuputira zvinobudirira inovandudza anti-oxidation kuita kwekunzwa kwakaoma;
(2)Short fiber hard wanzwa
Iyo yakazara inonzwa ine yakakwira porosity uye inopa nzira dzeokisijeni; iyo flake graphite coating ine yakasununguka chimiro, mashoma okisijeni nzira, uye yakagadziridzwa anti-oxidation performance; iyo yakavharwa girazi kabhoni yekuputira ine dense chimiro, mashoma eokisijeni nzira, uye yakanakisa anti-oxidation kuita.
2. High-tembiricha kugadzikana kwegirazi kabhoni coating pamusoro ablation
Iyo porous chimiro che plain inonzwa inogona kuderedza kupisa (kupisa convection heat dissipation); graphite bepa rinowanzoita blistering kana rabviswa; iyo ablation yakadzika yegirazi kabhoni coating ndiyo isina kudzika, uye yayo ablation kuramba ndiyo yakasimba; iyo girazi kabhoni coating ine yakanaka yekupisa yekuvharisa kuita.
3. Anti-Si erosion kuita kwegirazi kabhoni coating
Ipfupi faibha yakaoma inonzwa yakakukurwa uye yakasvibiswa neSi; flake graphite coating ine kupesana neSi erosion munguva pfupi; girazi kabhoni yekuputira ine yakanakisa anti-kukurwa kwekuita.
Chikonzero chikuru cheSi erosion ndechekuti Si gasification inokanganisa zvakananga pamusoro peiyo yakaoma inonzwa, zvichiita kuti upfu; nepo iyo kabhoni chimiro chegirazi kabhoni coating yakanyanya kugadzikana uye ine zvirinani anti-erosion performance.
Summary
Iyo girazi kabhoni yekuputira sisitimu haingo shandiswe pane zvinopisa zvekudzivirira zvinhu, asi zvakare inotarisirwa kushandiswa zvakananga pamusoro pezvikamu zvegraphite uye.C/C zvikamu, zvinobudirira kuvandudza kushanda kwesevhisi yakazara yezvinyorwa.
