Ana amfani da murfin injin tsotsar iska sosai a cikin kayan aikin mota, kayan aikin yankewa, ƙira, kayan lantarki, kayan ado, da sauran masana'antu don inganta aikin saman da halayen aiki. A lokacin aikin shafa, ana sanya siririn fim a saman substrate a ƙarƙashin yanayin injin tsotsar iska, yana samar da murfin aiki tare da takamaiman halaye kamar babban tauri, juriya ga lalacewa, juriya ga tsatsa, ƙarancin gogayya, ko bayyanar ado.
Tambayar da aka saba yi ita ce ko murfin injin zai shafi taurin kayan da aka yi amfani da su. Amsar ba lallai ba ce. A yawancin aikace-aikace, babban manufar murfin injin shine a gyara halayen saman kayan aikin maimakon canza manyan halayen injinan da ke cikin substrate. Duk da haka, ainihin tasirin ya dogara ne akan fasahar rufi, zafin aiki, kayan substrate, tsarin rufi, da sigogin aiki.
1. Rufin Injin Tsafta yana Canza Sifofin Fuskar Sama
Fasahar rufe injinan kamar PVD (Physical Vapor Deposition), PECVD (Plasma-Enhanced Chemical Vapor Deposition), da sauran hanyoyin ajiye injinan suna samar da wani siririn fim mai aiki a saman substrate.
Ba kamar maganin zafi mai yawa ba, wanda zai iya canza tsarin ƙarfe da halayen injiniya na wani abu a duk tsawon kauri, rufin injin gabaɗaya yana shafar saman saman ne kawai. Kauri na rufin yawanci yana cikin kewayon micrometer ko sub-micrometer, ya danganta da tsarin aikace-aikacen da kuma adanawa.
Misali, rufin PVD mai tauri kamar TiN, TiCN, CrN, TiAlN, da AlTiN na iya samar da tauri mai yawa da juriya ga lalacewa fiye da tushen da ke ƙasa. Duk da haka, wannan ba yana nufin cewa an canza tauri na dukkan substrate zuwa daidai gwargwado ba.
Saboda haka, lokacin da ake kimanta tasirin murfin injin a kan taurin kai, yana da mahimmanci a bambance tsakanin taurin substrate da taurin shafi.
2. Shin Rufin PVD Zai Iya Ƙara Taurin Sama?
A aikace-aikace da yawa, ana amfani da shafi na PVD musamman don haɓaka taurin saman.
Rufin da ke da tauri da aka ajiye ta hanyar tsari kamar ƙafewar arc na cathodic da kuma fitar da magnetron na iya samar da tsarin rufi mai kauri da mannewa mai ƙarfi tare da tauri mai yawa da kuma juriyar lalacewa mai kyau.
Misali, ga kayan aikin yankewa, murfin PVD mai tauri zai iya rage lalacewa, lalacewar mannewa, da gogayya a mahaɗin kayan aiki. Rufin yana aiki azaman layin saman kariya yayin da substrate ke ba da tauri da tallafin injiniya da ake buƙata.
Saboda haka, aikin ƙarshe ba wai kawai yana da taurin murfin da kansa ba, har ma da haɗin:
Taurin shafi + mannewa a shafi + kauri a shafi + taurin substrate + hanyar haɗin shafi/ƙasa + tsarin shafi.
Rufin da ke da tauri sosai ba ya tabbatar da ingantaccen aiki ta atomatik idan substrate ɗin ya yi laushi sosai ko kuma idan mannewar murfin bai isa ba.
3. Shin Zafin Shafi Zai Shafi Taurin Substrate?
Wannan yana ɗaya daga cikin mahimman abubuwan da ake buƙata don tantance ko murfin injin zai iya shafar taurin substrate.
Tsarin PVD da PECVD daban-daban suna aiki a cikin kewayon zafin jiki daban-daban. A lokacin da aka ajiye, substrate yana fuskantar kuzarin zafi da aka samar ta hanyar plasma, ion bombardment, tushen ƙafewa, ko wasu yanayin aiki.
Ga kayan da ke da saurin kamuwa da zafi, yawan zafin substrate ko kuma tsawon lokacin da aka ɗauka ana ɗaukar zafi na iya shafar ainihin tsarin da halayen injin.
Misali, wasu ƙarfe masu tauri suna samun halayen injinansu ta hanyar takamaiman hanyoyin kashewa da dumamawa. Idan zafin murfin ya wuce zafin zafin da ya dace, akwai yuwuwar tasirin dumamawa, wanda zai iya rage taurin substrate.
Saboda haka, ga ƙarfe masu tauri da sauran abubuwan da ke da saurin zafi, ya kamata a tsara tsarin shafawa bisa ga yanayin maganin zafi na kayan da kuma zafin aikin da aka yarda da shi.
4. Bam ɗin Ion da Gyaran Sama
A cikin hanyoyin PVD da yawa, ana yin amfani da sinadarin ion kafin da kuma lokacin da ake zubar da shi.
Yin etching na ion ko tsaftace plasma na iya cire gurɓatattun abubuwa a saman kuma kunna saman substrate, yana inganta mannewa a shafi. A lokacin da aka ajiye ion, fashewar ion da aka sarrafa kuma na iya yin tasiri ga yawan fim, damuwa da ta rage, tsarin microstructure, da mannewa a shafi.
Duk da haka, yawan kuzarin ion ko kuma ma'aunin tsari mara dacewa na iya haifar da tasirin da ba a so kamar dumama substrate mai yawa, lalacewar saman, ko ƙara damuwa da ta rage.
Saboda haka, ya kamata a sarrafa sigogi kamar ƙarfin bias, ƙarfin arc, ƙarfin fitarwa, matsin lamba na aiki, zafin substrate, da ƙimar ajiya yadda ya kamata bisa ga kayan substrate da tsarin rufi.
5. Taurin Rufi Ya Bambanta da Taurin Substrate
Rashin fahimta ta yau da kullun shine cewa kayan aiki suna "ƙara wahala" kawai saboda an saka wani abu mai tauri a saman sa.
A zahiri, rufin injin gabaɗaya yana ƙirƙirar Layer mai tauri, yayin da babban taurin substrate ya kasance mafi yawan ƙaddara ta yanayin kayan sa na asali da maganin zafi.
Misali, kayan aikin yanke carbide na iya samun wani abu mai tauri da kuma wani abu mai tauri na PVD. Rufin yana inganta juriyar lalacewa a saman da kuma aikin tribological, yayin da abin da ke cikin carbide yana ba da ƙarfi da tauri na tsari.
Hakazalika, ga sassan ƙarfe masu tauri, rufin PVD zai iya samar da farfajiya mai tauri da juriya ga lalacewa ba tare da canza taurin ƙarfen da ke ƙarƙashinsa ba, muddin zafin ajiyar ya kasance a cikin taga mai dacewa.
6. Yadda Ake Hana Rufin Injin Shafawa Daga Taurin Ƙasa
Domin kiyaye ainihin halayen injiniya na substrate, ya kamata a inganta tsarin shafa bisa ga kayan aiki da aikace-aikacen.
Da farko, ya kamata a tabbatar da kayan da aka yi amfani da su da kuma yanayin maganin zafi kafin a shafa su. Matsakaici daban-daban na ƙarfen kayan aiki, bakin ƙarfe, carbide, ƙarfen aluminum, da sauran kayan suna da iyaka daban-daban ta zafi.
Na biyu, ya kamata a sarrafa zafin murfin a cikin kewayon da ya dace. Ga kayan da ke da saurin zafi, ana iya zaɓar PVD mai ƙarancin zafin jiki ko wani tsari mai dacewa na adanawa.
Na uku, ya kamata a inganta sigogin tsari kamar ƙarfin lantarki na bias, kuzarin ion, yawan plasma, ƙimar ajiya, matsin lamba na aiki, da lokacin aiwatarwa don cimma aikin murfin da ake buƙata ba tare da tasirin zafi ko fashewar ion mai yawa ba.
A ƙarshe, ya kamata a tantance sassan da aka shafa ta hanyar gwaji mai dacewa, gami da gwajin microhardness, gwajin mannewa na shafi, gwajin lalacewa, auna tsatsa a saman, da kuma nazarin ƙarfe, ya danganta da aikace-aikacen.
7. Kammalawa
To, shin rufin injin yana shafar taurin kayan?
Gabaɗaya, rufin injina galibi tsari ne na injiniyan saman kuma an tsara shi ne don gyara halayen saman abu maimakon canza ƙarfinsa sosai. Rufin PVD mai tauri na iya inganta taurin saman sosai, juriyar lalacewa, halayen gogayya, juriyar tsatsa, da tsawon lokacin aiki yayin da yake kiyaye halayen injiniya na substrate.
Duk da haka, taurin asalin substrate na iya shafar idan tsarin rufewa ya haifar da yawan fallasa zafi ko kuma fashewar ion mara dacewa, musamman ga ƙarfe da aka yi wa magani da zafi da sauran kayan da ke da saurin kamuwa da zafin jiki.
Saboda haka, zaɓar fasahar adana injin da ta dace, kayan shafa, zafin substrate, yanayin fashewar ion, da sigogin tsari yana da mahimmanci.
Tare da daidaitaccen tsarin taga da kayan aiki, rufin injin zai iya cimma haɗin da ake so na taurin saman, manne mai ƙarfi, juriyar lalacewa, da kuma kaddarorin substrate masu ƙarfi, yana samar da ingantaccen mafita na injiniyan saman don aikace-aikacen masana'antu masu wahala.
