Ko te Silicon carbide (SiC) he matū honohono i hangaia mai i te waro me te silicon, ā, e mōhiotia ana mō ōna āhuatanga tino pai, tae atu ki te ātete kakahu teitei, te ātete ru wera, te ātete waikura kaha me te kawe wera teitei. Nā ēnei āhuatanga ka waiho te silicon carbide hei rauemi pai mō ngā momo tono i roto i ngā ahumahi maha, tae atu ki te rererangi, te hanga mīhini, ngā matū hinu, te whakarewa whakarewa me te hikohiko. He tino pai mō te hanga i ngā wāhanga ātete kakahu me ngā wāhanga hanganga pāmahana teitei. Ko te whanaketanga o ngā uku silicon carbide kua tauhohenga-whakakotahitia kua whai wāhi nui ki te whakatairanga i ngā tono ahumahi o tēnei rauemi maha-whakamahinga.
Te tikanga tuku iho mō te whakaputangā uku karāhe silicon carbide i whakamātauhia-tauhohengaKo te whakamahi i te paura silicon carbide i konatunatua ki te iti o te paura waro. Ka pāngia te ranunga e te tauhohenga siliconization pāmahana teitei hei hanga i tētahi rauemi uku matotoru. Heoi, kāore tēnei mahi toi tuku iho i te kore he ngoikoretanga. Ko te tukanga sintering e tohuhia ana e te roa o te wā, te pāmahana teitei me te nui o te whakapaunga pūngao, ka hua ake he utu whakaputa nui. I te mea ka uaua haere ngā whakaritenga ahumahi mō ngā āhua me ngā āhua uku silicon carbide, ka kitea haere ngā herenga o ngā tikanga tuku iho.
I ngā tau tata nei, kua waiho te whakaurunga o ngā paura nano silicon carbide hei otinga whai hua hei whakapai ake i ngā āhuatanga ā-pūkaha o ngā uku silicon carbide. Mā te whakamahi i ngā paura nano ka taea te whakaputa uku he nui ake te matotoru o te whakakā me te kaha piko teitei ake. Heoi, he tino teitei te utu o te paura nano silicon carbide, he maha ngā wā ka neke atu i te 10,000 yuan ia tana, he arai nui tēnei ki te whānui o te whakamahinga me te whakaputanga nui. Ko tēnei wero ōhanga me tūhura i ngā rauemi mata me ngā tikanga rerekē kia pai ake ai te mahi me te whai hua o te whakaputa uku silicon carbide.
Hei tāpiritanga, ko te kaha ki te whakaputa i ngā āhua uaua me ngā wāhanga nui ake ka whakatuwhera i ngā huarahi hou mō ngā tono uku silicon carbide. Ka taea e ngā ahumahi e hiahia ana ki ngā hoahoa uaua me ngā rauemi mahi teitei te whai hua mai i tēnei tikanga whakarite auaha. Ko te ngāwari o te hoahoa me te kaha ki te whakaputa papatipu o ngā uku silicon carbide kounga teitei ka arahi pea ki ngā whanaketanga nui i roto i ngā wāhanga pēnei i te rererangi me te hikohiko e tino hira ana te mahi rauemi.
