Uchwepheshe oqeqeshiwe kufanele aqaphele ukuthi indawo engaphezulu yesixhumi ibonakala ibushelelezi, kodwa iqhubu elingu-5-10 micron lisengabonwa ngaphansi kwesibonakhulu.Eqinisweni, ayikho into ebizwa ngokuthi indawo yensimbi ehlanzekile ngempela emkhathini ngisho nendawo yensimbi ehlanzeke kakhulu, lapho isichayeke emkhathini, izosheshe yakhe ifilimu yokuqala ye-oxide yama-microns ambalwa.Isibonelo, ithusi lithatha imizuzu engu-2-3 kuphela, i-nickel cishe imizuzu engama-30, futhi i-aluminium ithatha imizuzwana engu-2-3 kuphela ukwenza ifilimu ye-oxide enogqinsi lwama-microns angu-2 ebusweni bayo.Ngisho negolide lensimbi eliyigugu elizinzile ikakhulukazi, ngenxa yamandla alo aphezulu, indawo engaphezulu izokwakha ungqimba lwefilimu ye-organic adsorption.Izingxenye zokumelana nesixhumi zingahlukaniswa zibe: ukumelana okugxilile, ukumelana nefilimu, ukumelana nomqhubi.Ngokuvamile, izici eziyinhloko ezithinta ukuhlolwa kokumelana nesixhumi zimi kanje.
1. Ukucindezeleka okuhle
Ukucindezela okuhle koxhumana naye kungamandla asetshenziswa izindawo ezithintana futhi zibheke endaweni yokuxhumana.Ngokukhula kokucindezela okuhle, inombolo kanye nendawo yamaphoyinti amancane okuxhumana akhula kancane kancane, futhi ama-micro-points othintana nawo ashintsha kusuka ekuguquguqukeni okunwebekayo kuya ekuguqulweni kwepulasitiki.Ukumelana nokuxhumana kuncipha njengoba ukumelana nokugxila kuncipha.Ukucindezela kokuxhumana okuhle ikakhulukazi kuncike kujometri yokuxhumana kanye nezakhiwo ezibonakalayo.
2. Isimo sobuso
Ingaphezulu lokuxhumana liyifilimu elingaphezulu elixegayo elakhiwe ukunamathela komshini kanye nokufakwa kothuli, i-rosin namafutha ebusweni bokuxhumana.Lolu ngqimba lwefilimu engaphezulu kulula ukushumekwa emigodini emincane yendawo yokuxhumana ngenxa yezinhlayiya, ezinciphisa indawo yokuxhumana, zandisa ukumelana nokuxhumana, futhi azinzinzi ngokwedlulele.Okwesibili ifilimu yokungcola eyakhiwe ukukhangiswa ngokomzimba kanye ne-chemical adsorption.Indawo yensimbi ngokuyinhloko i-chemical adsorption, ekhiqizwa ngokufuduka kwe-electron ngemva kokukhangiswa ngokomzimba.Ngakho-ke, kweminye imikhiqizo enezidingo ezinokwethenjelwa okuphezulu, njengezixhumi zikagesi we-aerospace, kufanele kube nezimo zemvelo zokukhiqiza umhlangano ohlanzekile, inqubo yokuhlanza ephelele kanye nezinyathelo zokuvalwa kwesakhiwo ezidingekayo, futhi ukusetshenziswa kwamayunithi kufanele kube nokugcinwa okuhle nokusetshenziswa kwezimo zokusebenza zemvelo.
