Ukufakwa kwe-ceramization kumphezulu – ukutshiza nge-plasma kunye nokuveliswa kobushushu obuphezulu okuzisasaza ngokwako
Ukutshiza ngeplasma kuvelisa i-DC arc phakathi kwe-cathode kunye ne-anode. I-arc i-ionization yegesi esebenzayo ibe yiplasma enobushushu obuphezulu. Ilangabi leplasma lenziwa ukuze linyibilikise umgubo ukuze lenze amathontsi. Umsinga wegesi okhawulezayo ukhupha amathontsi aze awakhuphele kwi-substrate. Umphezulu wenza i-coating. Inzuzo yokutshiza ngeplasma kukuba ubushushu bokutshiza buphezulu kakhulu, ubushushu obuphakathi bunokufikelela ngaphezulu kwe-10 000 K, kwaye naluphi na uphahla lwe-ceramic oluphezulu lokunyibilika lungalungiswa, kwaye i-coating inoxinano oluhle kunye namandla aphezulu okubopha. Ingxaki kukuba ukusebenza kakuhle kokutshiza kuphezulu. Iindleko eziphantsi, nezibizayo zezixhobo, kunye notyalo-mali oluqala kanye ziphezulu.
I-self-propagating high-temperature synthesis (SHS) yiteknoloji yokwenza izinto ezintsha ngokuziqhubela ngokwazo ubushushu obuphezulu be-chemical reaction phakathi kwee-reactants. Inezibonelelo zezixhobo ezilula, inkqubo elula, ukusebenza kakuhle kwemveliso, ukusetyenziswa kwamandla aphantsi kwaye akukho ngcoliseko. Yiteknoloji yobunjineli bomphezulu efanelekileyo kakhulu ekukhuseleni udonga lwangaphakathi lweepayipi. I-ceramic lining elungiselelwe yi-SHS ineempawu zamandla aphezulu okubopha, ubulukhuni obuphezulu kunye nokumelana nokugqwala, okunokwandisa ubomi bombhobho ngempumelelo. Icandelo eliphambili le-ceramic liner esetyenziswa kwimibhobho yepetroleum yi-Fe+Al2O3. Le nkqubo kukuxuba ngokulinganayo umgubo we-iron oxide kunye nomgubo we-aluminium kumbhobho wentsimbi, uze ujikeleze ngesantya esiphezulu kwi-centrifuge, uze uvuthe nge-spark yombane, kwaye umgubo uyatsha. I-displacement reaction yenzeka ukuze yenze umaleko onyibilikisiweyo we-Fe+Al2O3. Umaleko onyibilikisiweyo ubekwe phantsi kwesenzo samandla e-centrifugal. I-Fe ikufutshane nodonga lwangaphakathi lombhobho wentsimbi, kwaye i-Al2O3 yenza i-ceramic inner liner kude nodonga lombhobho.
