Izembatho ze-PVD (Physical Vapor Deposition) seziphenduke into ethandwayo uma kuziwa ekuvikeleni indawo ekugqokeni. Ngamandla abo okuthuthukisa ukuqina kanye nokunciphisa ukungqubuzana, izintambo ze-PVD zivame ukusetshenziswa ezimbonini ezihlukahlukene ezihlanganisa ezezimoto, i-aerospace kanye nezokwelapha. Nokho, umbuzo ovame ukuvela ngowokuthi ingabe izimbotshana ze-PVD azikwazi yini ukungena emanzini. Kule bhulogi, sizohlola lesi sihloko futhi sikunikeze ulwazi oludingekayo.
Okokuqala, kubalulekile ukuqonda ukuthi yini PVD enamathela. I-PVD coating iyindlela yokufaka ungqimba oluncane lwempahla endaweni. Inqubo yenziwa endaweni ye-vacuum, eqinisekisa ukuthi ukugqoka kubambelela ngokulinganayo phezulu. Izinto ezisetshenziswa kakhulu zokumboza i-PVD yizinsimbi ezifana ne-titanium, i-chromium ne-aluminium. Lezi zinto zinokugqwala okuhle kakhulu kanye nokumelana nokuhuzuka, okuzenza zilungele ukusetshenziswa njengezingubo zokuvikela.
Manje, ake siphendule umbuzo osuseduze - ingabe ama-PVD angenawo amanzi? Impendulo emfushane ithi yebo. I-PVD yokugqoka inezinga eliphezulu lokumelana namanzi, okwenza ifaneleke izicelo ezivezwe kumswakama. Kodwa-ke, kufanele kuqashelwe ukuthi ukugqoka kwe-PVD akuvimbeli amanzi ngokuphelele. Nakuba ingamelana nokuchayeka okuvamile emanzini, ukucwiliswa isikhathi eside emanzini noma ukuchayeka kumakhemikhali anokhahlo ekugcineni kubeke engcupheni ukumelana kwayo namanzi.
Lapho unquma ukuthi ukugcotshwa kwe-PVD kuyisinqumo esifanele, kubalulekile ukucabangela izidingo ezithile zohlelo lwakho lokusebenza. Uma iphrojekthi yakho idinga ukuchayeka njalo emanzini, njengezinto zasolwandle noma izinto zokugezela, ukuvikela okwengeziwe kungase kudingeke. Kulesi simo, inhlanganisela ye-PVD yokugqoka kanye nesendlalelo sesibili sokuvimbela amanzi sizohlinzeka ngokuvikeleka okungcono kakhulu.
Njenganoma yikuphi ukugqoka, ukuphila nokusebenza kwezingubo ze-PVD kuncike ekunakekeleni okufanele. Ukuhlanza njalo nokunakekelwa okumnene kuzoyisiza ukuthi igcine ukumelana kwayo namanzi ngokuhamba kwesikhathi. Gwema izinto ezilimazayo noma amakhemikhali anokhahlo ngesikhathi sokuhlanza njengoba angase aklwebhele noma agxumeke okunamathelayo.
Muva nje, ukusetshenziswa kwe-PVD coating ezimbonini ezahlukahlukene kudonse ukunaka. Isibonelo esaziwayo imboni yezimoto, esebenzisa i-PVD coatings ukwandisa ukuqina kwezingxenye ezibalulekile. Ngaphezu kwalokho, ukuthuthuka kobuchwepheshe bokugqoka i-PVD kwenze kwaba nokwenzeka ukudala izimbotshana ezikhethekile ezihlose ukuvimbela amanzi. Lezi zembatho zisetshenziselwa ukukhiqizwa kwamawashi angangeni emanzini, ubucwebe kanye nemishini kagesi ukuze kunikeze isendlalelo esengeziwe sokuvikela emanzini.
Sengiphetha, izembatho ze-PVD zinikeza izinga elithile lokumelana namanzi, okuzenza zifanelekele uhla olubanzi lwezinhlelo zokusebenza. Kodwa-ke, kubalulekile ukuhlola izidingo ezithile zephrojekthi futhi ucabangele izinyathelo ezengeziwe zokuvimbela amanzi uma kunesidingo. Ngokunakekelwa okufanele nokugcinwa kahle, izimbotshana ze-PVD zinganikeza isivikelo esihlala isikhathi eside ekulimaleni, ekugqwaleni, ngisho nasekulimaleni kwamanzi. Ngakho-ke noma ngabe usembonini yezimoto, i-aerospace noma yezokwelapha, ukufaka okokunamathela kwe-PVD kumaphrojekthi akho kuyinketho eqinile.
