Yin amfani da sinadarin silicon carbide wajen haɗa sinadarai (reaction sintering silicon carbide) hanya ce mai mahimmanci don samar da kayan yumbu masu inganci. Wannan hanyar tana amfani da maganin zafi na tushen carbon da silicon a yanayin zafi mai yawa don sa su yi aiki ga yumbun silicon carbide.
1. Shirya kayan aiki. Kayan aiki na silicon carbide mai narkewar sinadarai sun haɗa da tushen carbon da tushen silicon. Asalin carbon yawanci shine baki na carbon ko polymer mai ɗauke da carbon, yayin da tushen silicon shine silica mai foda. Waɗannan kayan aikin suna buƙatar a niƙa su, a tace su kuma a gauraya su don tabbatar da girman barbashi iri ɗaya, yayin da kuma a sarrafa abubuwan da ke cikin su na sinadarai domin samun yumbu mai inganci na silicon carbide yayin maganin zafi.
2. Siffa. Sanya kayan da aka haɗa a cikin mold ɗin don yin ƙera. Akwai nau'ikan hanyoyin ƙera abubuwa da yawa, waɗanda aka fi amfani da su sune ƙera abubuwa da ...
3. Maganin zafi. An saka jikin yumbu da aka samar a cikin tanderun maganin zafi don yin siminti. Tsarin simintin ya kasu kashi biyu: matakin simintin carbon da matakin simintin. A matakin simintin carbon, ana dumama jikin yumbu zuwa babban zafin jiki (yawanci sama da 1600 ° C) a ƙarƙashin yanayi mara aiki, kuma tushen carbon yana amsawa da tushen silicon don samar da silicon carbide. A matakin simintin, ana ɗaga zafin zuwa mafi girman zafin jiki (yawanci sama da 1900 ° C), wanda ke haifar da sake sakewa da yawaita tsakanin ƙwayoyin silicon carbide. Ta wannan hanyar, ana ƙara inganta yawan jikin silicon carbide, yayin da kuma juriya da lalacewa suma suna inganta sosai.
4. Kammalawa. Ana buƙatar a gama jikin yumbu mai siminti domin samun siffar da girman da ake so. Hanyoyin kammalawa sun haɗa da niƙa, yankewa, haƙa, da sauransu. Saboda tsananin taurin kayan silicon carbide, yana da wuya a gama, yana buƙatar amfani da kayan niƙa masu inganci da kayan sarrafawa.
A taƙaice, tsarin samar da sinadarin silicon carbide mai narkewar sinadarai ya haɗa da shirya kayan aiki, gyaran fuska, gyaran fuska da kuma kammalawa. Daga cikinsu, babban matakin shine tsarin maganin zafi, wanda ke da matuƙar muhimmanci wajen samun kayan silicon carbide masu inganci. Ya zama dole a sarrafa zafin jiki, yanayi, lokacin riƙewa da sauran abubuwan da ke haifar da zafin jiki don tabbatar da cewa amsawar ta isa, an cika kristal ɗin kuma yawanta yana da yawa.
Amfanin tsarin samar da sinadarin silicon carbide mai narkewar sinadarai shine cewa ana iya shirya kayan yumbu masu ƙarfi, ƙarfi mai yawa, juriyar lalacewa mai yawa da kwanciyar hankali mai zafi. Wannan kayan ba wai kawai yana da kyawawan halayen injiniya ba, har ma yana da kyakkyawan juriya ga lalata da kuma kyawawan halayen zafin jiki. Ana iya amfani da kayan silicon carbide don ƙera sassa daban-daban na injiniya, hatimin injiniya, na'urorin sarrafa zafi, yumbu na tanderu da sauransu. A lokaci guda, ana iya amfani da kayan silicon carbide a cikin semiconductor, makamashin rana, kayan maganadisu da sauran fannoni.
A takaice, sinadarin silicon carbide mai hana ruwa shiga hanya ce mai mahimmanci don shirya kayan yumbu masu inganci. Tsarin samarwa yana buƙatar kulawa mai kyau ga kowace hanyar haɗi don samun kayan silicon carbide masu inganci. Kayan silicon carbide mai hana ruwa shiga shiga suna da kyawawan halayen injiniya, juriya ga tsatsa da kuma yanayin zafi mai yawa, kuma suna da fa'idodi masu yawa na amfani a fannoni daban-daban na masana'antu da kimiyya.
