Hanyoyi don Inganta Ƙarfin Injini na Layer Fim

A inji Properties na membrane Layer suna shafar mannewa, danniya, tara yawa, da dai sauransu Daga dangantakar dake tsakanin membrane Layer abu da kuma tsari dalilai, za a iya gani cewa idan muna so mu inganta inji ƙarfi na membrane Layer, ya kamata mu mayar da hankali a kan wadannan sigogi sigogi:

(1) matakin vacuum. Vacuum akan aikin fim ɗin a bayyane yake. Yawancin alamun wasan kwaikwayo na fim ɗin fim sun dogara sosai akan matakin injin. Yawancin lokaci, yayin da digiri na digiri ya karu, girman haɗin fim yana ƙaruwa, ƙarfin yana ƙaruwa, tsarin fim ɗin yana inganta, tsarin sinadaran ya zama mai tsabta, amma a lokaci guda damuwa kuma yana ƙaruwa.

(2) Yawan ajiya. Haɓaka adadin ƙididdigewa ba wai kawai za a iya amfani da shi don inganta ƙimar ƙawancen ruwa ba, wato, ƙara yawan tsarin zafin jiki na tushen evaporation, kuma za a iya amfani da shi don ƙara yawan hanyar da za a yi amfani da shi don cimmawa, amma yin amfani da tushen evaporation don ƙara yawan zafin jiki na tsarin yana da nasa drawbacks: sa membrane Layer damuwa yana da girma; iskar gas mai yin fim yana da sauƙin ruɗewa. Don haka, wani lokacin ƙara yankin tushen evaporation fiye da inganta yanayin yanayin ƙanƙara ya fi dacewa.

(3) zafin jiki. Ƙara yawan zafin jiki na substrate yana da kyau ga adsorption a kan substrate surface na sauran gas kwayoyin don ware, ƙara da substrate da dauri da karfi tsakanin ajiya kwayoyin: a lokaci guda zai inganta hira da jiki adsorption zuwa sinadaran adsorption, inganta hulda tsakanin kwayoyin, don haka da cewa membrane Layer tsarin ne m. Alal misali, Mg, membrane, substrate dumama zuwa 250 ~ 300 ℃ iya rage ciki danniya, inganta tara yawa, ƙara taurin da membrane Layer: substrate dumama zuwa 120 ~ 150 ℃ shirya Zr03-Si02, multilayer membrane, ta inji ƙarfi ya karu da yawa, amma substrate da za a iya rage yawan zafin jiki Layer.

(4) ion bombardment. Ion bombardment yana da tasiri akan samuwar filaye masu haɗaka sosai, rashin ƙarfi, oxidation da tara yawan. Bam ɗin kafin sutura zai iya tsaftace farfajiyar kuma ya kara mannewa; da bombardment bayan shafi iya inganta fim Layer aggregation yawa, da dai sauransu, don haka kara da inji ƙarfi da taurin.

(5) Tsabtace ma'auni. Hanyar tsaftacewa na substrate bai dace ba ko kuma ba mai tsabta ba, a cikin ragowar ƙazantattun ƙazanta ko tsaftacewa, sa'an nan kuma haifar da sabon gurbatawa, a cikin suturar yanayi daban-daban na haɗin kai da mannewa, wanda ya shafi farkon Layer na tsarin kaddarorin da kauri na gani, amma kuma yin fim ɗin fim ɗin yana da sauƙi don fitowa daga substrate, don haka canza halaye na fim din Layer.
