Kemikari kupisa kupisa inzira yekurapa kupisa umo iyo workpiece inoiswa mune chaiyo svikiro yekudziya uye kuchengetedza kupisa, kuitira kuti maatomu anoshanda ari mukati apinde mukati mechikamu chepamusoro cheiyo workpiece, nekudaro achichinja chimiro chemakemikari uye chimiro cheiyo. pamusoro peiyo workpiece, uyezve kuchinja maitiro ayo. Kemikari kupisa kurapwa ndiyo imwe yenzira dzekuwana kuomarara kwepamusoro, kuoma uye lining. Kuenzaniswa nekudzima kwepamusoro, kurapwa kwemakemikari kupisa hakungoshandure chimiro chepamusoro chesimbi, asiwo chinoshandura chimiro chayo chemakemikari. Maererano nezvinhu zvakasiyana-siyana zvakapindirwa, makemikari ekupisa kupisa anogona kugoverwa kuva carburizing, nitriding, multi-infiltration, kupindira kwezvimwe zvinhu, nezvimwewo. Mushonga wekugadzirisa kupisa kwemakemikari unosanganisira maitiro matatu ekutanga: kuparara, kutora, uye kupararira.

Inowanzo shandiswa kemikari kupisa kurapwa:

Carburizing, nitriding (inowanzozivikanwa se nitriding), carbonitriding (inowanzozivikanwa se cyanidation uye nitriding yakapfava), etc. Sulfurizing, boronizing, aluminizing, vanadizing, chromizing, etc.

Kupfekedza simbi imwe kana yakawanda pamusoro pechigadziko chinhu chinogona kuvandudza zvakanyanya kusakara kwayo, kusagadzikana kwekuora uye kupisa kupisa, kana kuwana zvimwe zvakakosha. Kune electroplating, makemikari plating, composite plating, infiltration plating, inopisa dip plating, vacuum evaporation, spray plating, ion plating, sputtering nedzimwe nzira.

Metal Carbide Coating - Vapor Deposition

Vapor deposition tekinoroji inoreva rudzi rutsva rwetekinoroji yekupfeka iyo inoisa mhute-chikamu zvinhu zvine deposition zvinhu pamusoro pezvinhu nenzira dzemuviri kana kemikari kugadzira mafirimu matete.

Zvinoenderana nemusimboti we deposition process, vapor deposition tekinoroji inogona kukamurwa kuita mapoka maviri: yemuviri vapor deposition (PVD) uye kemikari vapor deposition (CVD).

Physical vapor deposition inoreva tekinoroji umo chinhu chinonyungudutswa kuita maatomu, mamorekuru kana ionized kuita ayoni nenzira dzemuviri pasi pemamiriro evacuum, uye firimu rakatetepa rinoiswa pamusoro pechinhu kuburikidza nechikamu chegasi.

Tekinoroji yekuisa tekinoroji inonyanya kusanganisira nzira nhatu dzekutanga: vacuum evaporation, sputtering, uye ion plating.

Physical vapor deposition ine akawanda anoshanda substrate zvinhu uye firimu zvinhu; nzira yacho iri nyore, inochengetedza zvinhu, uye haina kusvibiswa; iyo firimu yakawanikwa ine zvakanakira kunamatira kwakasimba kune iyo firimu base, yunifomu yefirimu ukobvu, compactness, uye mashoma pinholes.

Chemical vapor deposition (Chemical vapor deposition) zvinoreva nzira inodyidzana negasi rakasanganiswa nepamusoro pechikamu pane imwe tembiricha kuita simbi kana firimu remukomboni pamusoro pepasi.

Nekuti iyo kemikari vapor deposition firimu ine yakanaka kupfeka kuramba, corrosion resistance, kupisa kupisa uye magetsi, optical nezvimwe zvinhu zvakakosha, yakashandiswa zvakanyanya mukugadzira michina, aerospace, zvekufambisa, marasha kemikari indasitiri uye mamwe maindasitiri minda.
