Nano Hafnium carbide HfC foda
1. Halayen kayan hafnium carbide:
(1) Hafnium carbide (HfC) foda ne mai launin toka-baki tare da tsarin cubic mai tsayin daka da babban wurin narkewa (3890°C).Wani abu ne da ke da babban wurin narkewa a cikin sanannen fili guda ɗaya kuma babban rufin ƙarfe ne mai narkewa.Kyakkyawan abu.
(2) Daga cikin abubuwan da aka sani, hafnium alloy (Ta4HfC5) tare da babban narkewa shine hafnium gami (Ta4HfC5).Hafnium alloy abu na 1 part na hafnium carbide da 4 sassa na tantalum carbide yana da wani narkewa batu na 4215 ℃, don haka za a iya amfani da shi azaman tsarin kayan a kan jet injuna da daodan.
(3) Hafnium carbide yana da babban adadin kuzari na kaza, mai kyau na wutar lantarki da yanayin zafi, ƙaramin haɓakar haɓakar thermal da ingantaccen juriya.Ya dace da filin kayan bututun roka kuma yana da mahimmancin cermet.

3. Amfanin hafnium carbide:
(1) Hafnium carbide wani babban zafin jiki ne, kayan yumbu mai juriya na yanghua, wanda ke da fa'idodin ingantaccen wutar lantarki da yanayin zafi da ƙarancin haɓakar thermal.Hafnium carbide ya dace da kera mahimman sassa kamar nozzles na roka da gaban fuka-fuki, kuma ana amfani dashi galibi a cikin rataye, yumbu na masana'antu da sauran fannoni.
(2) Hafnium carbide yana da tsayin daka, ana iya amfani dashi azaman siminti carbide additives, yana iya samar da ingantaccen bayani tare da mahadi masu yawa (kamar ZrC, TaC, da sauransu), kuma an yi amfani dashi sosai a fagen yankan kayan aiki da gyare-gyare.
(3) Hafnium carbide yana da babban haɓaka mai ƙarfi, ingantaccen wutar lantarki da haɓakar thermal, ƙaramin haɓakar haɓakar thermal da ingantaccen juriya.Ya dace da kayan bututun roka kuma ana iya amfani dashi a cikin mazugin hanci na roka.Yana da aikace-aikace masu mahimmanci a filin sararin samaniya.Hakanan akwai mahimman aikace-aikace a cikin nozzles, rufin juriya mai zafi, na'urorin lantarki don baka ko lantarki.
(4) Hafnium carbide yana da kyakkyawan kwanciyar hankali mai ƙarfi, juriya na sinadarai, kuma yana da yuwuwar dacewa da amfani a cikin yanayin zafi mai zafi.Bugu da kari, fitar da fim din HfC a saman katode na carbon nanotube na iya inganta aikin fitar da fili sosai.
(5) Ƙara hafnium carbide zuwa C / C composites zai iya inganta juriya na ablation.Hafnium carbide yana da kyawawan kaddarorin jiki da sinadarai da yawa, yana sanya shi amfani da shi sosai a cikin kayan zafi mai zafi na yanzu.
