Mumakore apfuura, kwave nekufambira mberi kukuru mumunda we tekinoroji yekuputira, imwe yacho iri kuuya kwetekinoroji yePVD (Physical Vapor Deposition). Iyi tekinoroji yemazuva ano inosanganisa kunaka kwekubuda kwechiedza cheelectron beam nekunyatsoita kwePVD kuti igadzire maitiro ekuputira anoshanda zvakanaka uye emhando yepamusoro.
Saka, chii chaizvo chinonzi e-beam PVD? Muchidimbu, zvinosanganisira kuisa mafirimu matete panzvimbo dzakasiyana-siyana uchishandisa danda remaerekitironi ane simba guru. Danda iri rinoita kuti chinhu chaunoda chipfungaire, icho chobva chabatana nesubstrate yaunoda kuti chigadzire jira rakatetepa, rakafanana. Mugumisiro wacho unogara kwenguva refu uye unoyevedza zvinoita kuti e-beam PVD ive sarudzo yekutanga yekushandiswa kwakasiyana-siyana.
Chimwe chezvakanakira zvikuru zve e-beam PVD kugona kuputira zviri nyore maumbirwo akaomarara uye zvivakwa. Izvi zvinoreva kuti maindasitiri akadai semotokari, ndege nemagetsi anogona kubatsirwa zvikuru nehunyanzvi uhwu. Ingava chifukidziro chekudzivirira zvikamu zvendege kana kupedzisa kwekushongedza zvemagetsi evatengi, electron beam PVD inoita basa rakanaka kwazvo.
Chimwe chinhu chinoonekwa nezve electron beam PVD ndechekuti haikuvadzi nharaunda. Kusiyana netsika dzechinyakare dzekuputira, idzo dzinowanzo sanganisira makemikari ane njodzi, electron beam PVD inzira yakachena uye inogara kwenguva refu. Inogadzira marara mashoma uye haina simba rakawanda panharaunda, zvichiita kuti ive yakanaka kumakambani ane chinangwa chekuderedza kukanganiswa kwecarbon.
Pamusoro pezvo, chifukidziro chePVD chedanda remaerekitironi chine kunamatira kwakanaka uye kuomarara, zvichiita kuti chive nedziviriro inogara kwenguva refu kubva pakusakara, ngura nedzimwe nzira dzekuora. Simba rakawanda redanda remaerekitironi rinobvumira kutonga kwakanyatsojeka pamusoro peukobvu uye maumbirwo ejira, zvichibvumira mainjiniya kugadzirisa chifukidziro kuti chienderane nezvinodiwa chaizvo.
Nhau dzakabuda munguva pfupi yapfuura dzekuti sangano guru rekutsvagisa razivisa nezvebudiriro mu tekinoroji yePVD yemagetsi. Chikwata chavo chakabudirira mukuwedzera zvakanyanya mwero wekuisa zvinhu pasina kukanganisa kunaka kwependi. Kufambira mberi uku kunovhura mikana mitsva kumaindasitiri anoda kugadzirwa nekukurumidza pasina kukanganisa mhando.
Mukupedzisa, e-beam PVD inomiririra shanduko huru mu tekinoroji yekuputira. Kukwanisa kwayo kupa hunhu hwakanaka, kushanduka-shanduka uye hunhu hwezvakatipoteredza kunoita kuti ive mhinduro inozivikanwa mumaindasitiri akasiyana siyana. Sezvo tsvakurudzo nekuvandudzwa kwakawanda kuri kuramba kuchivandudza tekinoroji, tinotarisira kuti e-beam PVD iwedzere kushandiswa mukugadzira, kukurudzira hunyanzvi uye kugadzira zvigadzirwa zvemhando yepamusoro.
