Mashandiro EPVD: Kufumura Zvakavanzika ZveTekinoroji Iyi Yemazuva Ano
Nzvimbo yekufambira mberi kwetekinoroji iri kuramba ichichinja, ichipa mhinduro itsva kumaindasitiri akasiyana-siyana. Imwe yenzira dzakadaro itekinoroji yePVD (Physical Vapor Deposition), iyo inounza divi idzva muinjiniya yepamusoro. Muchinyorwa chino cheblog, tichaongorora zvakadzama mashandiro anoita PVD uye kuongorora kuti tekinoroji iyi inoshamisa iri kuchinja sei nzvimbo dzakasiyana-siyana.
PVD, sezvinoreva zita racho, inosanganisira kuisa mafirimu matete panzvimbo dzakasimba kuburikidza nemaitiro chaiwo. Tekinoroji iyi inoshandisa misimboti yakasiyana yekuvandudza kugara kwenguva refu, kushanda zvakanaka uye runako rwezvigadzirwa zvakasiyana-siyana. Saka, ngatinyatsoongorora mashandiro anoita PVD uye tinzwisise zvazvinoreva.
Chinangwa chePVD kugadzira nzvimbo yekubvisa tsvina mukati mekamuri rakagadzirwa zvakanaka. Iyi vacuum inovimbisa kubviswa kwechero tsvina, zvichipa nzvimbo yakakodzera yekuputira. Kana kamuri remuchina ravharwa, chinhu chakanangana nacho (chinogona kuva simbi, alloy, ceramic kana kunyange polymer) chinopiswa zvakanyanya. Nekuda kweizvozvo, maatomu kana mamorekuru ari muchinhu chakanangana nacho anoshanduka kuita gasi.
Zvino kwava nechikamu chikuru chekushanda kwePVD - kuisa maatomu aya egasi kana mamorekuru pamusoro pechinhu chaunoda. Kuti izvi zviitike, panodiwa simba rakawanda senge arc kana plasma. Simba iri rinoputira maatomu, zvichiita kuti aparare oita gore replasma. Gore replasma rinosundira maatomu kumusoro, uko maatomu anoungana oita firimu rakatetepa.
Maitiro ePVD ane zvakanakira zvakawanda pane nzira dzechinyakare dzekuputira. Chekutanga, inobvumira kudzora kwakaringana ukobvu uye maumbirwo efirimu rakaiswa. Vagadziri vanogona kuwana machira akafanana zvakanaka, kunyangwe pazvimiro zvakaoma uye zvinhu zvakaoma kunzwisisa. Chechipiri, firimu rePVD rinonamira zvakanaka pachigadziko, zvichiita kuti rigare kwenguva refu uye rirambe richidzivirira kupfeka. Pamusoro pezvo, tekinoroji yePVD inobvumira kuiswa kwemachira ane hunhu hwakasiyana senge kuomarara kwakanyanya, kukweshana kushoma uye kuramba ngura kwakanaka.
Kushandiswa kwePVD kwakakura zvikuru uye kunosanganisira maindasitiri akasiyana-siyana. Kubva kuzvikamu zvemotokari nezvishandiso zvekucheka kusvika pakushongedza uye zvishandiso zvekurapa, tekinoroji iyi iri kuchinja nzira yatinoshandisa pakugadzira zvigadzirwa zvezuva nezuva. Semuenzaniso, machira ePVD pazvishandiso zvekucheka anogona kuwedzera hupenyu hwawo, zvichideredza kudiwa kwekuchinjwa nguva nenguva. Saizvozvowo, machira ePVD pazvikamu zvemotokari anowedzera kugara kwenguva refu uye kushanda zvakanaka, zvichibatsira kuvandudza kushandiswa kwemafuta uye kuderedza kusvibiswa kwemhepo.
Zvakazoburitswa pachena munguva pfupi yapfuura kuti masayendisiti anga achiongorora mukana wekuti PVD inoshanda sei musimba rinogona kushandiswazve. Nekushandisa maPVD coatings kuma solar panels, vaongorori vanovavarira kuwedzera kushanda kwavo uye hupenyu hwavo hwese. Saizvozvowo, maPVD coatings pama wind turbine blades anogona kuwedzera kuramba kwavo kukurwa, nokudaro achiwedzera kugadzirwa kwesimba.
Pfungwa yekuti PVD inoshanda sei inyanzvi itsva yakachinja mainjiniya epamusoro. Nekudzora nekunyatsoisa mafirimu matete, maPVD coating anovandudza kugara kwenguva refu, mashandiro uye runako rwezvigadzirwa zvakasiyana-siyana. Nekushandiswa kwayo kwakasiyana-siyana mumaindasitiri, tekinoroji iyi yemazuva ano inoramba ichigadzira nzira yekufambira mberi. Rambai makagadzirira sezvatinoburitsa zvimwe zvinhu zvinonakidza mumunda wePVD.
