1. Iimpawu zezinto ze-hafnium carbide:

(1) I-Hafnium carbide (i-HfC) i-powder grey-black kunye nesakhiwo se-cubic ejongene nobuso kunye neqondo eliphezulu lokunyibilika (3890 ° C).Yimpahla enendawo ephezulu yokunyibilika kwindawo eyaziwayo eyodwa kwaye iyindawo ephezulu yokunyibilika yesinyithi enyibilikisa i-crucible lining.Izinto ezilungileyo.

(2) Phakathi kwezinto ezaziwayo, i-hafnium alloy (Ta4HfC5) enendawo ephezulu yokunyibilika i-hafnium alloy (Ta4HfC5).I-hafnium alloy material ye-1 inxalenye ye-hafnium carbide kunye neengxenye ze-4 ze-tantalum carbide ine-melting point ye-4215 ℃, ngoko ingasetyenziselwa njengezinto zokwakha kwiinjini ze-jet kunye ne-daodan.

(3) I-Hafnium carbide ine-coefficient ephezulu ye-elastic ye-hen, i-electrical conductivity elungileyo kunye ne-thermal conductivity, i-coefficient encinci yokwandisa i-thermal kunye nokuchasana kwempembelelo efanelekileyo.Ifanelekile kwintsimi yezixhobo ze-rocket nozzle kwaye iyinto ebalulekileyo ye-cermet.

3. Ukusetyenziswa kwe-hafnium carbide:

(1) I-Hafnium carbide yinto ephezulu yokumelana nobushushu, i-yanghua ekwazi ukumelana ne-ceramic imathiriyeli, enenzuzo yombane kunye ne-thermal conductivity kunye nokwandiswa kwe-thermal ephantsi.I-Hafnium carbide ifanelekile ukwenza iindawo ezibalulekileyo ezifana ne-rocket nozzles kunye ne-wing fronts, kwaye isetyenziswa kakhulu kwi-hangtian, i-ceramics yezoshishino kunye nezinye iindawo.

(2) I-Hafnium carbide inobunzima obuphezulu, ingasetyenziselwa njengezongezo ze-carbide ze-cemented, inokwenza isisombululo esiqinileyo kunye neengqungquthela ezininzi (ezifana ne-ZrC, i-TaC, njl.), kwaye isetyenziswe ngokubanzi kwintsimi yezixhobo zokusika kunye nokubunjwa.

(3) I-Hafnium carbide ine-coefficient ephezulu ye-elastic, i-coefficient yombane kunye ne-thermal conductivity, i-coefficient encinci yokwandisa i-thermal kunye nokuchasana kwempembelelo efanelekileyo.Ifanelekile kwizixhobo ze-rocket nozzle kwaye ingasetyenziselwa kwi-cone yempumlo yeerokethi.Inezicelo ezibalulekileyo kwindawo ye-aerospace.Kukho izicelo ezibalulekileyo kwimibhobho, i-high-temperature resistant linings, i-electrodes ye-arc okanye i-electrolysis.

(4) I-Hafnium carbide inozinzo oluluqilima oluluqilima, ukumelana neekhemikhali, kwaye inamandla okuba ilungele ukusetyenziswa kwiindawo ezinobushushu obuphezulu.Ukongeza, ukukhupha ifilimu ye-HfC kumphezulu we-carbon nanotube cathode kunokuphucula kakhulu ukusebenza kwayo kokukhupha intsimi.

(5) Ukongezwa kwe-hafnium carbide kwii-composites ze-C / C kunokuphucula ukuxhathisa kwayo.I-Hafnium carbide ineempawu ezininzi ezibalaseleyo zomzimba kunye neekhemikhali, iyenza isetyenziswe ngokubanzi kwizinto ezikhoyo zobushushu obuphezulu.
