Ndeipi nzira yeCVD yemadhaimani?

Iyo kemikari vapor deposition (CVD) nzira yedhaimondi inosanganisira kushandisa kemikari maitiro kugadzira firimu redhaimani kana kuvhara munzvimbo inodzorwa. Munzira iyi, musanganiswa wegasi, kazhinji une hydrocarbon magasi akadai semethane, unounzwa mukamuri rekuita pamwe chete ne substrate zvinhu senge molybdenum wafers kana diamond wafers. Gasi rinobva raitwa nenzira dzakasiyana, sekupisa kana plasma, kuputsa mamorekuru ehydrocarbon uye kuisa maatomu ecarbon pane substrate, zvichikonzera kukura kwemakristasi edhaimondi.

Iyo CVD maitiro edhaimondi inopa akati wandei mabhenefiti, kusanganisira kugona kuburitsa emhando yepamusoro madhaimani machira ane chaiyo kutonga kwehukobvu, kufanana uye kuumbwa. Inobvumirawo kuiswa kwemafirimu emadhaimani pane akasiyana siyana substrate zvinhu, zvichigonesa kugadzirwa kwedhaimani-yakavharwa zvikamu zveakasiyana maindasitiri nekutsvaga mashandisirwo.

Pakazere, iyo CVD nzira yedhaimondi inzira inogoneka uye inoshandiswa zvakanyanya kugadzira mafirimu edhaimani ekugadzira uye machira ane zvimiro zvakajairwa, zvichiita kuti ave akakosha mumaindasitiri akadai semagetsi, maturusi ekucheka, uye machira asingapfeki.

Chii chinonzi kuoma kweCVD coating?

Kuomarara kwemakemikari vapor deposition (CVD) machira anogona kusiyana zvichienderana nechaiyo zvinhu zvakaiswa uye maitiro maparamita anoshandiswa. Nekudaro, machira eCVD anozivikanwa nekuomarara kwawo kusingaenzaniswi, kazhinji kudarika iwo echinyakare muviri vapor deposition (PVD) machira.

Kune madhaimani CVD machira, kuomarara kunonyanya kukosha. Dhaimondi ndechimwe chezvinhu zvakaoma zvikuru zvinozivikanwa, uye CVD madhaimani majasi ane kuomarara kwakasiyana kunowanzopfuura kwemamwe marudzi emajasi. Kuomarara kweCVD madhaimani machira anowanzo kuyerwa uchishandisa Vickers kuomarara chiyero uye kubva pa8000 HV kusvika pamusoro pe10000 HV, zvichiita kuti ive imwe yezvinhu zvakaoma uye zvisingapfeki.

Kune mamwe maCVD machira, akadai se carbide kana nitride-based coatings, kuomarara kunogona zvakare kuve kwakakwira, ichipa yakanakisa kupfeka kuramba uye kusimba mumhando dzakasiyana dzemaindasitiri ekushandisa.

Pakazere, machira eCVD anokosheswa nekuomarara kwavo kwakasarudzika, zvichiita kuti ive yakakodzera kune maapplication uko kupfeka kuramba, kusimba kwepamusoro-tembiricha, uye kushanda kwenguva refu kwakakosha.
