Surface ceramization - kupfapfaidza kweplasma uye kuzviparira tembiricha yakakwira synthesis
Kupfapfaidza kwePlasma kunoburitsa DC arc pakati pecathode neanode. Iyo arc inonanisa gasi rinoshanda kuita tembiricha yeplasma. Murazvo weplasma unoumbwa kunyungudusa hupfu kuita madonhwe. Iyo yakakwirira velocity gasi rukova runoita atomize madonhwe uye yobva yaaburitsa kune substrate. Iyo yepamusoro inoumba chifukidzo. Zvakanakira kupfapfaidza yeplasma ndeyokuti tembiricha yekupfapfaidza yakanyanya kwazvo, tembiricha yepakati inogona kusvika pamusoro pe10 000 K, uye chero yakakwira yekunyunguduka yedongo remachira inogona kugadzirwa, uye iyo yekupfeka ine density yakanaka uye yakakwirira bonding simba. Izvo zvisingabatsiri ndezvokuti kupfapfaidza kushanda kwakakwirira. Yakaderera, uye inodhura michina, imwe-nguva mari yekudyara yakakwira.
Self-propagating high-temperature synthesis (SHS) itekinoroji yekugadzira zvinhu zvitsva nekuzviitisa kwekupisa kwemakemikari akakwira pakati pezvinoita. Iine zvakanakira midziyo iri nyore, nzira iri nyore, kugadzirwa kwepamusoro, kushandiswa kwesimba shoma uye pasina kusvibiswa. Iyo tekinoroji yeinjiniya yepamusoro iyo yakakodzera kwazvo kuchengetedzwa kwemadziro emukati emapombi. Iyo ceramic lining yakagadzirirwa neSHS ine hunhu hwekusimba kwepamusoro, kuomarara kwepamusoro uye kushorwa kwemarara, izvo zvinogona kunyatso kuwedzera hupenyu hwepombi. Chinhu chikuru checeramic liner inoshandiswa mumapaipi epetroleum ndeye Fe + Al2O3. Maitiro acho ndeekusanganisa zvakafanana iron oxide poda nealuminium poda mupombi yesimbi, uye wozotenderedza nekumhanya kukuru pacentrifuge, wobva wabatidza nemagetsi, uye hupfu huri kutsva. Iyo yekutamisa maitiro inoitika kuti igadzire yakanyungudutswa yeFe + Al2O3. Iyo yakanyungudutswa yakanyungudutswa yakaturikidzana pasi pekuita kwe centrifugal force. Fe iri padyo nemadziro emukati mepombi yesimbi, uye Al2O3 inoumba ceramic yemukati liner kure nemadziro epombi.
