Kusimbisa pamusoro pemvura - kupfapfaidza plasma uye kugadzira kwega kupisa kwakanyanya
Kupfapfaidza kweplasma kunogadzira DC arc pakati pe cathode ne anode. Arc inoita kuti gasi rinoshanda rive plasma inodziya zvakanyanya. Murazvo weplasma unoumbwa kuti unyungudise hupfu kuti hugadzire madonhwe. Gasi rinoyerera nekukurumidza rinoita atomu yemadonhwe uye rozoaburitsa ku substrate. Pamusoro payo panoita coating. Chakanakira kupfapfaidza kweplasma ndechekuti tembiricha yekupfapfaidza yakanyanya, tembiricha yepakati inogona kusvika pamusoro pe 10 000 K, uye chero ceramic coating yepamusoro inogona kugadzirwa, uye coating yacho ine density yakanaka uye yakasimba yekubatanidza. Chakashata ndechekuti kushanda zvakanaka kwekupfapfaidza kwakakwira. Midziyo yakaderera, inodhura, uye mari yekudyara kamwe chete yakakwira.
Kugadzira zvinhu zvitsva zvinozvigadzira nega (SHS) tekinoroji yekugadzira zvinhu zvitsva kuburikidza nekuzvigadzira kupisa kwakanyanya kwemakemikari pakati pema reactants. Ine zvakanakira zvemidziyo iri nyore, maitiro ari nyore, kushanda zvakanaka kwekugadzira, kushandiswa kwesimba shoma uye kusasvibiswa. Itekinoroji yekugadzira pamusoro yakakodzera kwazvo kuchengetedza madziro emukati memapaipi. Rutivi rweceramic rwakagadzirwa neSHS rune hunhu hwekusimba kwekubatanidza, kuomarara kwakanyanya uye kuramba ngura, izvo zvinogona kuwedzera hupenyu hwepaipi. Chikamu chikuru che ceramic liner chinoshandiswa mumapaipi epetroleum iFe+Al2O3. Maitiro acho ndeekusanganisa zvakafanana iron oxide powder nealuminium powder mupaipi yesimbi, uye wozotenderera nekukurumidza pa centrifuge, wobva wabatidza ne electric spark, uye upfu hwacho hwava kutsva. Kuchinjana kwekuita kunoitika kuti pave nechikamu chakanyungudutswa cheFe+Al2O3. Chigadziko chakanyungudutswa chakapetwa pasi pesimba re centrifugal. Fe iri pedyo nemadziro emukati mepaipi yesimbi, uye Al2O3 inoumba ceramic inner liner kure nemadziro epaipi.
