gabatarwa:
A duniyar injiniyan saman da aka ci gaba, Fizik Vapor Deposition (PVD) ya fito a matsayin hanya mafi dacewa don haɓaka aiki da dorewar kayan aiki daban-daban. Shin kun taɓa mamakin yadda wannan dabarar zamani take aiki? A yau, muna zurfafa cikin dabarun PVD masu rikitarwa, muna ba da cikakken fahimtar aikinta da fa'idodin da take bayarwa. Ci gaba da karatu don gano ayyukan ciki na PVD da mahimmancinta a masana'antu daban-daban.
Fahimtar PVD:
Fizik Tururin Tsami, wanda aka fi sani da PVD, wata dabara ce ta adana sirara wacce ta ƙunshi canja wurin ƙwayoyin halitta ko ƙwayoyin halitta daga tushe mai ƙarfi zuwa saman ta hanyar amfani da hanyoyi na zahiri. Ana amfani da wannan dabarar sosai don haɓaka halayen saman abubuwa daban-daban, kamar ƙarfe, robobi, yumbu, da sauransu. Ana yin tsarin PVD a ƙarƙashin yanayin iska, yana tabbatar da cikakken iko kan samuwar siraran fina-finai.
Tsarin PVD:
Ana iya rarraba tsarin PVD zuwa manyan matakai guda huɗu: shiri, ƙafewa, ajiyar ruwa, da girma. Bari mu bincika kowane mataki dalla-dalla.
1. Shiri:
Kafin fara aikin adanawa, ana tsaftace kayan da za a shafa sosai. Wannan matakin yana tabbatar da cewa saman ba shi da gurɓatattun abubuwa, kamar mai, yadudduka na oxide, ko ƙwayoyin cuta na waje, waɗanda za su iya hana mannewa.

Ana sanya kayan tushe a cikin ɗakin injin, inda ake sarrafa shi da makamashin zafi ko na'urar lantarki. Sakamakon haka, ƙwayoyin halitta ko ƙwayoyin halitta daga kayan tushe suna tururi, suna samar da kwararar ruwa.
3. Ajiyewa:
Da zarar kayan tushen sun ƙafe, tururin yana ratsawa ta cikin ɗakin injin ya isa saman substrate ɗin. Substrate ɗin, wanda galibi kayan da za a shafa, yana nan kusa da tushen tururin. A wannan lokacin, ƙwayoyin tururin suna mamaye saman substrate ɗin, wanda ke haifar da ɓoyewar wani siririn fim.
4. Girma:
Da kowace kwayar zarra ko molecule ta sauka a kan substrate, siririn fim ɗin yana girma a hankali. Ana iya sarrafa yanayin wannan tsarin girma ta hanyar daidaita sigogi kamar lokacin adanawa, zafin jiki, da matsin lamba. Waɗannan sigogi suna ba da damar sarrafa kauri, daidaito, da abun da ke ciki na fim ɗin, wanda a ƙarshe ke haifar da halaye na musamman don biyan takamaiman buƙatu.
