CVD (Chemical Vapor Deposition) hanya ce da aka saba amfani da ita don shirya suturar carbide na silicon.CVD silicon carbide coatingssuna da halaye na musamman na musamman. Wannan labarin zai gabatar da hanyar shiri na CVD silicon carbide shafi da halayen aikin sa.
1. Hanyar shiri naCVD silicon carbide shafi
Hanyar CVD tana jujjuya abubuwan da ke haifar da iskar gas zuwa ingantattun suturar siliki carbide ƙarƙashin yanayin zafi mai ƙarfi. Dangane da mabanbantan iskar gas daban-daban, ana iya raba shi zuwa lokacin CVD na gas da lokacin ruwa CVD.
1. Lokacin tururi CVD
Lokacin Vapor CVD yana amfani da precursors gaseous, yawanci organosilicon mahadi, don cimma ci gaban silicon carbide fina-finai. Abubuwan da aka saba amfani da su na organosilicon sun haɗa da methylsilane, dimethylsilane, monosilane, da sauransu, waɗanda ke samar da fina-finai na siliki carbide akan abubuwan ƙarfe na ƙarfe ta hanyar jigilar abubuwan da ke haifar da iskar gas zuwa ɗakuna masu zafin jiki. Wuraren zafin jiki mai girma a cikin ɗakin amsa yawanci ana haifar da su ta hanyar dumama sawa ko dumama juriya.
2. Ruwa lokaci CVD
Liquid-phase CVD yana amfani da precursor na ruwa, yawanci wani kaushi na halitta mai ɗauke da siliki da silanol fili, wanda aka yi zafi da tururi a cikin ɗaki na amsawa, sannan an samar da fim ɗin siliki carbide akan substrate ta hanyar sinadarai.
2. Performance halaye naCVD silicon carbide shafi
1.Excellent high zafin jiki yi
CVD silicon carbide coatingsbayar da kyau kwarai high zafin jiki kwanciyar hankali da hadawan abu da iskar shaka juriya. Yana da ikon yin aiki a cikin yanayin zafi mai zafi kuma yana iya jure matsanancin yanayi a yanayin zafi mai girma.
2.Good inji Properties
CVD silicon carbide shafiyana da high taurin da kuma kyau lalacewa juriya. Yana kare abubuwan ƙarfe daga lalacewa da lalata, yana ƙara rayuwar sabis na kayan.
3. Kyakkyawan kwanciyar hankali sunadarai
CVD silicon carbide coatingssuna da matukar juriya ga sinadarai na yau da kullun kamar acid, alkalis da gishiri. Yana tsayayya da harin sinadarai da lalata na substrate.
4. Low gogayya coefficient
CVD silicon carbide shafiyana da ƙarancin juzu'i mai kyau da kyawawan kaddarorin sa mai. Yana rage juzu'i da lalacewa kuma yana inganta ingantaccen amfani da kayan aiki.
5.Good thermal watsin
CVD silicon carbide shafi yana da kyawawan halayen halayen thermal. Yana iya sauri gudanar da zafi da kuma inganta zafi watsawa yadda ya dace da karfe tushe.
6.Excellent lantarki rufi Properties
CVD silicon carbide shafi yana da kyawawan kaddarorin wutar lantarki kuma yana iya hana ɗigogi na yanzu. Ana amfani da shi sosai a cikin kariya ta kariya ta na'urorin lantarki.
7. Daidaitaccen kauri da abun da ke ciki
Ta hanyar sarrafa yanayin yayin aiwatar da CVD da ƙaddamarwa na precursor, za a iya daidaita kauri da abun da ke ciki na fim din siliki carbide. Wannan yana ba da zaɓuɓɓuka da yawa da sassauci don aikace-aikace iri-iri.
A takaice, CVD silicon carbide shafi yana da kyakkyawan aikin zafin jiki mai kyau, kyawawan kaddarorin injina, kwanciyar hankali mai kyau na sinadarai, ƙarancin juzu'i, kyakkyawan yanayin zafi da kaddarorin wutar lantarki. Waɗannan kaddarorin suna yin suturar silikon carbide na CVD da ake amfani da su sosai a fannoni da yawa, gami da kayan lantarki, na'urorin gani, sararin samaniya, masana'antar sinadarai, da sauransu.
