Shiri da kaddarorin yumburan silicon carbide ta hanyar yin sintering

Silicon carbide (SiC) wani sinadari ne mai hade da carbon da silicon kuma an san shi da kyawawan halaye, gami da juriyar lalacewa mai yawa, juriyar girgizar zafi, juriyar tsatsa mai ƙarfi da kuma yawan zafin jiki. Waɗannan halaye suna sanya silicon carbide ya zama kayan aiki mai kyau don aikace-aikace iri-iri a cikin masana'antu da yawa, gami da sararin samaniya, kera injina, sinadarai na petrochemicals, narkewar ƙarfe da na'urorin lantarki. Ya dace musamman don samar da sassan da ke jure lalacewa da sassan tsarin zafin jiki mai yawa. Ci gaban yumburan silicon carbide masu narkewar amsawa sun taka muhimmiyar rawa wajen haɓaka aikace-aikacen masana'antu na wannan kayan mai amfani.

Hanyar gargajiya ta samar da kayayyakiyumbun silicon carbide mai narkewashine a yi amfani da foda na silicon carbide tare da ƙaramin adadin foda na carbon. Haɗin yana fuskantar amsawar siliconization mai zafi don samar da kayan yumbu mai yawa. Duk da haka, wannan sana'ar gargajiya ba ta da lahani. Tsarin simintin yana da alaƙa da dogon lokaci, yawan zafin jiki da yawan amfani da makamashi, wanda ke haifar da hauhawar farashin samarwa. Yayin da buƙatun masana'antu don siffofi da siffofi na silicon carbide na yumbu ke ƙara zama masu rikitarwa, iyakokin hanyoyin gargajiya suna ƙara bayyana.

A cikin 'yan shekarun nan, gabatar da na'urorin silicon carbide sun zama mafita mai kyau don inganta halayen injiniya na yumburan silicon carbide. Amfani da na'urorin nanopowder na iya samar da yumbu masu yawan sintered da ƙarfin lankwasawa. Duk da haka, farashin na'urorin silicon carbide yana da tsada sosai, sau da yawa ya wuce yuan 10,000 a kowace tan, wanda ke haifar da babban cikas ga karɓuwa da kuma samar da kayayyaki masu yawa. Wannan ƙalubalen tattalin arziki yana buƙatar bincika wasu kayan aiki da hanyoyi don sa samar da na'urorin silicon carbide ya fi yiwuwa kuma ya fi araha.

Bugu da ƙari, ikon samar da siffofi masu rikitarwa da manyan sassa yana buɗe sabbin hanyoyi don amfani da yumbu na silicon carbide. Masana'antu da ke buƙatar ƙira masu rikitarwa da kayan aiki masu inganci za su iya amfana daga wannan sabuwar hanyar shiri. Sauƙin ƙira da yuwuwar samar da taro na yumbu mai inganci na silicon carbide na iya haifar da manyan ci gaba a fannoni kamar sararin samaniya da na'urorin lantarki inda aikin abu yake da mahimmanci.
