1. Thevacuum evaporation coatinginzira ikubiyemo guhumeka ibikoresho bya firime, gutwara atome ziva mumyuka mwinshi, hamwe na nucleation no gukura kwa atome ziva kumyuka hejuru yakazi.
2. Impanuka ya vacuum igipimo cya vacuum evaporation coating ni kinini, muri rusange 10-510-3Pa. Inzira yubusa ya molekile ya gaze ni 1 ~ 10m itondekanya ubunini, ikaba iruta kure cyane intera iva mumyuka iva mukigero cyakazi, iyi ntera yitwa intera ihumeka, muri rusange 300 ~ 800mm. Ibice bitwikiriye ntibishobora guhura na molekile ya gaze na atome ziva mu kirere kandi bigera ku kazi.
3. Igikoresho cyo guhumeka cya vacuum ntabwo ari ugukomeretsa ibikomere, kandi atome ziva mu kirere zihita zerekeza ku kazi munsi y’imyuka myinshi. Gusa uruhande rwerekeranye nisoko yumwuka kurupapuro rwakazi rushobora kubona urwego rwa firime, kandi uruhande ninyuma yibikorwa ntibishobora kubona urwego rwa firime, kandi urwego rwa firime rufite plaque mbi.
4. Ingufu zuduce duto twa vacuum evaporation coating layer ni nkeya, kandi ingufu zigera kumurimo nimbaraga zubushyuhe zitwarwa numwuka. Kubera ko igihangano kidafite aho kibogamiye mugihe cyo gutwika vacuum, atome yicyuma yishingikiriza gusa ku bushyuhe bwo guhumeka mu gihe cyo guhumeka, ubushyuhe bwo guhumeka ni 1000 ~ 2000 ° C, kandi ingufu zitwarwa zingana na 0.1 ~ 0.2eV, bityo ingufu z’ibice bya firime zikaba nke, imbaraga zo guhuza ibice bya firime na matrix ni nto, kandi biragoye gukora co.
5. Igice cya vacuum gihumeka gifite imiterere myiza. Igikoresho cyo guhumeka cya vacuum gikozwe munsi yumuvu mwinshi, kandi uduce twa firime mumyuka mubyinshi mubipimo bya atome, bikora intangiriro nziza hejuru yumurimo.
