Silicon Carbide (SiC) machiraari kukurumidza kuve akakosha mumhando dzakasiyana-siyana dzekushanda kwepamusoro nekuda kweanoshamisa emuviri uye makemikari zvimiro. Inoshandiswa kuburikidza nehunyanzvi sePhysical kana Chemical Vapor Deposition (CVD), kana nzira dzekupfapfaidza,SiC coatingsshandura iyo yepamusoro zvimiro zvezvikamu, zvichipa kusimba kwakawedzera uye kuramba kune yakanyanyisa mamiriro.
Sei SiC Coatings?
SiC inozivikanwa nekunyungudika kwayo kwakakwira, kuomarara kwakasarudzika, uye kurwisa kwepamusoro kune ngura uye oxidation. Hunhu uhu hunogadziraSiC coatingskunyanya kushanda mukudzivirira mamiriro akakomba akasangana muaerospace uye maindasitiri ekudzivirira. Kunyanya, SiC's yakanakisa ablation kuramba patembiricha iri pakati pe1800-2000 ° C inoita kuti ive sarudzo yakanaka yezvishandiso zvinoda hupenyu hurefu uye kuvimbika pasi pekupisa kwakanyanya uye kushushikana kwemagetsi.
Common Nzira dzeSiC CoatingApplication:
1.Chemical Vapor Deposition (CVD):
CVD inzira yakapararira apo chikamu chinofanira kuputirwa chinoiswa muhubhu inopindirana. Uchishandisa Methyltrichlorosilane (MTS) sechinhu chinotangira, SiC inoiswa panzvimbo yechikamu patembiricha dzinobva 950-1300 ° C pasi pemamiriro epasi-kudzvinyirira. Iyi nzira inovimbisa yunifomu,high-quality SiC coating, kuwedzera kusimba kwechikamu uye hupenyu.
2.Precursor Impregnation uye Pyrolysis (PIP):
Iyi nzira inosanganisira pre-kurapwa kwechikamu chinoteverwa nevacuum impregnation mune ceramic precursor solution. Mushure mekudzivirira, chikamu chinopinda pyrolysis muchoto, umo inotonhorera kusvika kune tembiricha. Mhedzisiro ndeye yakasimba SiC coating iyo inopa yakasarudzika dziviriro kubva pakupfeka uye kukukurwa.
Zvishandiso uye Zvakanakira:
Kushandiswa kweSiC coatings kunowedzera hupenyu hwezvinhu zvakakosha uye kunoderedza mari yekuchengetedza nekupa yakaoma, inodzivirira layer inodzivirira pakuparara kwezvakatipoteredza. Mumuchadenga, semuenzaniso, machira aya akakosha mukudzivirira kubva mukupisa kwekupisa uye kupfeka kwemagetsi. Mumidziyo yemauto, SiC coatings inosimudzira kuvimbika uye kuita kwezvikamu zvakakosha, kuve nechokwadi chekushanda kwekuvimbika kunyangwe pasi pemamiriro akaomarara.
Mhedziso:
Sezvo maindasitiri achiramba achisundidzira miganhu yekushanda uye kusimba, SiC coatings ichaita basa rakakosha mukufambisira mberi kwezvinhu zvesainzi uye engineering. Nekutsvagisa kunoenderera mberi nekusimudzira, SiC coatings pasina mubvunzo ichawedzera kusvika kwavo, ichiisa miitiro mitsva mune yakakwirira-yekuita machira.
