Ukwahlulwa kwengubo (ukungaphumeleli kokuncamathelisa) yingxaki eqhelekileyo yomgangatho kwiiteknoloji yokufaka i-vacuum, echaphazela ngokuthe ngqo ukuthembeka kwemveliso, ukuqina kwayo, kunye nokusebenza kwayo. Eli nqaku lihlalutya ngokucwangcisiweyo izizathu ezisisiseko zokwahlukana kwemveliso ngokwembono yokunamathelana kwe-interfacial, iiparameter zenkqubo, iipropati zezinto, kunye nezinto ezingqongileyo, ngelixa licebisa amaqhinga okuphucula ahambelanayo.
1. Ukunamathela okunganelanga kwi-Interfacial
Amandla okuncamathela phakathi kwengubo kunye ne-substrate abalulekile ekuthinteleni ukuqhekeka. Izinto ezingcolisayo kumphezulu (umz., iioyile, ii-oxides, okanye ukufuma okufunxiweyo) okanye ukungonelanga konyango lwangaphambi kobuso (umz., ukucocwa kwe-plasma, ukuqhushumba kwe-ion) kunokunciphisa amandla okunxibelelanisa, okukhokelela ekuqhekekeni kwengubo kwindawo ethile okanye epheleleyo. Ukongeza, ukungafani kwi-coefficient of thermal expansion (CTE) phakathi kwe-substrate kunye nengubo kuvelisa uxinzelelo lwangaphakathi ngexesha lemijikelo yobushushu, nto leyo ebeka emngciphekweni ukunamathela.
2. Ulawulo olungafanelekanga lweeParamitha zeNkqubo
Inqanaba leVacuum elaneleyo: Iimolekyuli zegesi eziseleyo (umz., O₂, H₂O) ezifakwe ngexesha lokufakwa kwezakhiwo ezinemingxuma okanye izigaba zokungcola, nto leyo enciphisa uxinano lwe-coating.
Izinga lokuTshintshwa okugqithisileyo: Ukukhula ngokukhawuleza kwengubo kungenisa iziphene (umz., iimbobo, izakhiwo zekholamu), okwandisa uxinzelelo.
Ubushushu obungafanelekanga be-Substrate: Ubushushu obuphantsi buthintela ukuhamba kwee-athomu, buthintela ukuxinana; ubushushu obugqithisileyo bunokubangela ukusasazeka kwe-interfacial okanye utshintsho lwesigaba, okwenza iileya ezibuthathaka.
I-Voltage ye-Bias engaqhelekanga okanye amandla e-Plasma: Ukuqhushumba kwe-ion okungalinganiyo kunokubangela umonakalo phakathi kwe-interfacial okanye uxinzelelo olugqithisileyo.
3. Ukukhethwa kwezinto kunye neempazamo zoyilo
Uyilo olubi lweNkqubo yokuGcina: Ukungabikho kweeleya zotshintsho okanye iileya ezifanayo kukhokelela kuxinzelelo olukhawulezileyo lwe-interfacial.
Ukuqina/Uburhabaxa beSubstrate obungangqinelaniyo: Iindawo ezigudileyo kakhulu zinciphisa ukuxinana koomatshini, ngelixa uburhabaxa obuphezulu bunokubangela ukugquma okanye ukugoba okungalinganiyo.
4. Izinto ezichaphazela indalo kunye nezonyango emva konyango
Ukuvezwa emva kokususwa kwe-thermal cycling, i-mechanical shock, okanye i-chemical corrosion kunokubangela i-delanitation ngenxa yoxinzelelo lokudinwa okanye i-corrosive diffusion. Unyango olungafanelekanga emva konyango (umz., ii-annealing parameters ezingalunganga) nazo zinokubangela uxinzelelo olongezelelweyo.
Izisombululo ezicetyiswayo
Lungiselela iinkqubo zokucoca i-substrate kunye nokusebenza kwayo, ezifana nokucoca i-Ar⁺ sputter okanye unyango lwangaphambi kokusabela.
Lawula ngokuchanekileyo izinga lokufakwa kwezinto, ubushushu be-substrate, kunye namandla e-bias, ubandakanya ukujonga indawo ehleli kuyo.
Lungiselela uyilo lwe-coating ngokusebenzisa i-simulation, udibanise iileya ze-stress buffer (umz., iileya ze-Cr okanye ze-Ti transition).
Misela iindlela zokuhlola umgangatho ezingqongqo, kuquka neendlela zokuvavanya ukunamathela ezifana novavanyo lokukrwela kunye novavanyo lokutsala.
Ukuqukumbela, ukwahlukana kwengubo kuvela kwiintsebenziswano ezininzi. Indlela ebanzi edibanisa ukuphuculwa kwenkqubo kunye nokuveliswa kwezinto ezintsha ibalulekile ukuphucula ukusebenza kwezixhobo ezifakwe kwinkonzo.
