Vacuum coating inoreva kudziyisa uye kubudisa evaporation sosi muvacuum kana kupfapfaidza nekukasira bhomba ion, nekuiisa pamusoro pe substrate kuti igadzire firimu-layer kana akawanda-layer firimu. Chii chinonzi vacuum coating? Zvadaro, mupepeti weRSM anozozvisuma kwatiri.
1. Vacuum evaporation coating
Evaporation coating inoda kuti chinhambwe chiri pakati pemamorekuru emhute kana maatomu kubva kumhepo inoputika uye substrate ichaputirwa inofanira kunge iri shoma pane avhareji yemahara nzira yemamorekuru egasi asara mukamuri yekuputira, kuitira kuti ive nechokwadi chekuti mamorekuru emhute. evaporation inogona kusvika pamusoro pe substrate pasina kudhumhana. Ita shuwa kuti firimu rakachena uye rakasimba, uye evaporation haizoiti oxidize.
2. Vacuum sputtering coating
Muvacuum, kana maion anomhanyisa achidhumhana nechakasimba, kune rumwe rutivi, kristaro yakuvadzwa, kune rimwe divi, inodhumhana nemaatomu anoumba kristaro, uye pakupedzisira maatomu kana mamorekuru ari pamusoro pechinhu chakasimba. buda kunze. Iyo sputtered material inoputirwa pane substrate kuita firimu rakatetepa, iro rinonzi vacuum sputter plating. Kune nzira dzakawanda dzekupopota, pakati peiyo diode sputtering ndiyo yekutanga. Zvinoenderana neakasiyana cathode tarisiro, inogona kukamurwa kuita yakananga ikozvino (DC) uye yakakwirira frequency (RF). Huwandu hwemaatomu akapfapswa nekukanganisa nzvimbo yakanangwa neion inonzi sputtering rate. Nehupamhi hwekupopota, kukurumidza kwekugadzira firimu kunokurumidza. The sputtering rate inoenderana nesimba uye rudzi rwemaion uye rudzi rwezvinhu zvinotarirwa. Kazhinji kutaura, mwero wekupopota unowedzera nekuwedzera kwesimba reion remunhu, uye mwero wekupopota wesimbi dzinokosha wakakwira.
