Kwiminyaka edlulileyo, kubekho inkqubela phambili ebalulekileyo kwicandelo lobuchwepheshe bokugquma, enye yazo kukufika kwetekhnoloji ye-electron beam PVD (Physical Vapor Deposition). Le tekhnoloji iphambili idibanisa ukugqwesa kokufudumeza kwe-electron beam kunye nokuchaneka kwe-PVD ukudala inkqubo yokugquma esebenza kakuhle nesemgangathweni ophezulu.
Ngoko ke, yintoni kanye kanye i-e-beam PVD? Ngamafutshane, kubandakanya ukufaka iifilimu ezincinci kwiindawo ezahlukeneyo kusetyenziswa umqadi wee-electron ezinamandla aphezulu. Lo mqadi utshisa izinto ekujoliswe kuzo zibe ngumphunga, uze emva koko zijike zibe yi-substrate efunekayo ukuze zenze uqweqwe olubhityileyo nolufanayo. Isiphumo sisiphelo esiqinileyo nesinomtsalane esenza i-e-beam PVD ibe lukhetho lokuqala kwiintlobo ngeentlobo zezicelo.
Enye yezona nzuzo ziphambili ze-e-beam PVD kukukwazi ukugquma ngokulula iimilo kunye nezakhiwo ezintsonkothileyo. Oku kuthetha ukuba amashishini afana neemoto, i-aerospace kunye ne-elektroniki anokungenelwa kakhulu kobu buchwepheshe. Nokuba yingubo yokukhusela izixhobo zeenqwelo-moya okanye ukugqitywa kokuhombisa kwe-elektroniki yabathengi, i-electron beam PVD inika ukusebenza okugqwesileyo.
Olunye uphawu oluphawulekayo lwe-electron beam PVD kukuba inobuhlobo nokusingqongileyo. Ngokungafaniyo neendlela zemveli zokugquma, ezidla ngokubandakanya iikhemikhali eziyingozi, i-electron beam PVD yinkqubo ecocekileyo nehlala ixesha elide. Ivelisa inkunkuma encinci kwaye inempembelelo encinci kwindalo esingqongileyo, nto leyo eyenza ukuba ibe yeyona ifanelekileyo kwiinkampani ezijonge ukunciphisa umngcipheko wekhabhoni.
Ukongeza, i-electron beam PVD coating inamathela kakuhle kwaye ilukhuni, iqinisekisa ukhuseleko oluhlala ixesha elide ekugugeni, ukugqwala kunye nezinye iindlela zokuwohloka. Amandla aphezulu e-electron beam avumela ulawulo oluchanekileyo phezu kobukhulu kunye nokwakheka kwe-coating, okuvumela iinjineli ukuba zilungelelanise i-coating ukuze ihlangabezane neemfuno ezithile.
Kutshanje kuvele iindaba zokuba iziko lophando eliphambili libhengeze impumelelo kwitekhnoloji ye-electron beam PVD. Iqela labo liphumelele ekwandiseni kakhulu izinga lokufakwa kwezinto ngaphandle kokuphazamisa ukuthembeka kwengubo. Olu phuculo luvula amathuba amatsha kumashishini afuna imijikelo yemveliso ekhawulezayo ngaphandle kokuphazamisa umgangatho.
Ukuqukumbela, i-e-beam PVD imele inkqubela phambili kubuchwepheshe bokugquma. Amandla ayo okubonelela ngomgangatho ogqwesileyo, ukuguquguquka kunye neempawu zokusingqongileyo kuyenza ibe sisisombululo esithandwayo kumashishini onke. Njengoko uphando nophuhliso oluninzi luqhubeka nokuphucula ubuchwepheshe, silindele ukuba i-e-beam PVD ixhaphake ngakumbi kwimveliso, ukuqhuba ubuchule kunye nokudala iimveliso ezisemgangathweni.
