I-vacuum coating isho ukushisisa nokuhwamuka komthombo wokuhwamuka endaweni engenalutho noma ukufafaza ngebhomu ye-ion esheshayo, nokuyibeka phezu kwe-substrate ukuze kwakhe ungqimba olulodwa noma ifilimu enezendlalelo eziningi.Uyini umgomo we-vacuum coating?Okulandelayo, umhleli we-RSM uzosethula kithi.
1. I-vacuum evaporation coating
Ukufakwa komhwamuko kudinga ukuthi ibanga eliphakathi kwama-athomu omhwamuko noma ama-athomu asuka emthonjeni womhwamuko kanye ne-substrate ezogcotshwa kufanele libe ngaphansi komzila wamahhala wama-molecule egesi ayinsalela egumbini lokumboza, ukuze kuqinisekiswe ukuthi ama-molecule omhwamuko ukuhwamuka kungafinyelela phezu kwe-substrate ngaphandle kokungqubuzana.Qinisekisa ukuthi ifilimu ihlanzekile futhi iqinile, futhi ukuhwamuka ngeke kukhiphe i-oxidize.
2. I-vacuum sputtering coating
Ku-vacuum, lapho ama-ion asheshayo eshayisana nokuqinile, ngakolunye uhlangothi, ikristalu ilimele, ngakolunye uhlangothi, ashayisana nama-athomu akha ikristalu, futhi ekugcineni ama-athomu noma ama-molecule angaphezulu kokuqinile. phumela ngaphandle.I-sputtered material ifakwe ku-substrate ukuze kwakheke ifilimu elincanyana, elibizwa ngokuthi i-vacuum sputter plating.Kunezindlela eziningi zokuphalaza, phakathi kwazo ukuphalaza kwe-diode kuyindlela yokuqala.Ngokwemigomo ehlukene ye-cathode, ingahlukaniswa ibe yamanje eqondile (DC) kanye ne-high frequency (RF).Inombolo yama-athomu afafazwe ngokuba nomthelela endaweni okuqondiswe kuyo nge-ion ibizwa ngokuthi izinga lokuqhuqha.Ngezinga eliphezulu lokufafaza, isivinini sokwakheka kwefilimu siyashesha.Izinga lokufafaza lihlobene namandla nohlobo lwama-ion kanye nohlobo lwento eqondiwe.Ngokuvamile, izinga lokufafaza liyakhula ngokwanda kwamandla e-ion yomuntu, futhi izinga lokufafaza kwezinsimbi eziyigugu liphakeme.
