Iyo vacuum coating process ine zvakaomesesa zvinodiwa zvenzvimbo yekushandisa. Kune yakajairwa vacuum maitiro, ayo anonyanya kudiwa evacuum hutsanana ndeaya: hapana yakaunganidzwa kusvibiswa sosi pane zvikamu kana pamusoro pemidziyo iri muvacuum, pamusoro pekamuri yekuvhaira inotsvedzerera uye isina zvinyoro zvinyoro, pores nenzvimbo yekona, saka weld mumushini wevacuum haizokanganisa vacuum, uye iyo yakakwira vacuum muchina haizoshandisi muchina wemafuta. Iyo isina mafuta-yepamusoro-yepamusoro vacuum system inofanirwa kudzivirira pesvedzero yehutsi hwemafuta pakuchena, kushanda kwekushanda kana hunhu hwepamusoro hwepakati yekushanda. Iyo yekupedzisira-yakakwira vacuum simbi sisitimu inowanzo shandisa 1Cr18Ni9Ti seyakaumbwa zvinhu. Murabhoritari kana musangano umo muchina wekuputira vacuum unofanirwa kuchengetwa wakachena uye uine hutsanana.
Mukuita kwekuputira vacuum, kurapa kwekuchenesa kwepamusoro kwakakosha. Chaizvoizvo, ma substrates ese asati atakurwa mukamuri yekuvharira vacuum, ivo vanofanirwa kuenda kuburikidza ne pre-plating yekuchenesa maitiro kuti vawane degreasing, decontamination uye dehydration yebasa-chidimbu.
Nzvimbo huru dzekusvibiswa kwepasi kwezvikamu zvakaputirwa ndeidzi: guruva, ziya, girisi, polishing paste, mafuta, mafuta ekuzora uye zvimwe zvinhu zvinozoteedzerwa panguva yekugadzira, kutapurirana, kurongedza uye mamwe maitiro; Gasi adsorbed uye kunyudzwa pamusoro pamusoro midziyo zvikamu; Iyo oxide film yakaumbwa pamusoro pezvikamu zvemuchina wekupfekedza mumhepo yakanyorova. Nekusvibiswa kubva kune aya masosi, mazhinji acho anogona kubviswa ne degreasing kana kemikari kuchenesa.
Usachengete zvakacheneswa basa-zvidimbu munzvimbo yemhepo. Kuti uderedze kusvibiswa kweguruva uye uchenese kuchengetedza kwekushanda-zvimedu, kazhinji shandisa kuchenesa makabati kana midziyo yakavharwa kuchengetedza basa-chidimbu. Iyo girazi substrate inoda kuchengetwa mumudziyo uchangobva oxidized aruminiyamu, iyo inogona kuderedza adsorption yehydrocarbon vapor. Nekuti achangobva oxidized aruminiyamu midziyo inozonyanya kushambadza mahydrocarbon. Nzvimbo dzepamusoro dzinonzwa mhute yemvura kana kusagadzikana zvakanyanya dzinowanzochengetwa muvheni yekuomesa.
Izvo zvinodiwa zvevacuum coating process pane zvakatipoteredza zvinonyanya zvinosanganisira: kuchena kwepamusoro mukamuri yekutsvaira, guruva risina mukamuri yekuputira, etc. Mune dzimwe nzvimbo, hunyoro hwemhepo hunenge hwakakwirira, saka usati waputira, haufaniri kuchenesa chete zvikamu mu substrate uye vacuum chamber, asiwo unoda kuita basa rekubheka uye degassing. Mukuwedzera, kuitira kudzivirira mafuta kuti apinde mukamuri yevacuum, inofanirwawo kuterera kukudzoka kwemafuta uye matanho ekuvhara mafuta epombi yekuparadzira.
