(1) Unyango lwangaphambi kwe-PVD, kuquka ukucocwa kwezinto kunye nonyango lwangaphambili.Iindlela zokucoca ezikhethekileyo zibandakanya ukucocwa kwe-detergent, ukucocwa kwe-solvent chemical, ukucocwa kwe-ultrasonic, kunye nokucoca i-ion bombardment.
(2) Zifake kwiziko, kubandakanywa ukucocwa kwegumbi le-vacuum kunye nezixhobo, kunye nofakelo, ukugunyaziswa kunye nokudibanisa izinto kunye nezixhobo.
(3) Ukucoca, ukumpompa ngokubanzi ukuya kwi-6.6Pa okanye ngaphezulu, vula umphambili wempompo yokusasaza kwangaphambili ukugcina impompo yokufunxa kunye nokutshisa impompo yokusasaza.Emva kokufudumala ngokwaneleyo, i-valve ephakamileyo ivuliwe kwaye iphonswe kwi-6 x 10-3 Pa isiqingatha se-vacuum ephantsi kunye nepompo yokusabalalisa.
(4) Ukubhaka, ukubhaka izinto kubushushu obufunwayo.
(5) I-ion bombardment, i-vacuum ngokubanzi i-10 Pa ukuya kwi-10-1 Pa, i-ion bombardment voltage yi-voltage ephezulu engalunganga ye-200 V ukuya kwi-1 KV, kwaye ixesha lokuhlaselwa li-15 min ukuya kwi-30 min.
(6) Ukunyibilika kwangaphambili, ukulungelelanisa i-current ukuze kuncibilike izinto eziphathekayo, ukulungelelanisa i-current ukuze kuncibilike i-plating kunye ne-degassing ye-1min ~ 2min.Ukubekwa komphunga.Umsinga wokuguquka kwamanzi ulungelelaniswa njengoko kufuneka kude kube lixesha elifunekayo lokubeka.Ukupholisa, izinto zipholile kwiqondo lokushisa elithile kwigumbi le-vacuum.
(7) Emva kokuba izinto zikhutshiwe, igumbi lokucoca livaliwe, i-vacuum ikhutshwe kwi-l × l0-1Pa, kwaye ipompo ye-diffusion ipholile kwiqondo lokushisa elivumelekileyo ngaphambi kokuba umpompo wokulondoloza kunye namanzi okupholisa acinywe.
