Deqing Yehui Ceramic Parts Manufacture Co., Ltd. iri muDeqing County, Huzhou City, Zhejiang Province, China.Iyo ingangoita 200km kubva kuchiteshi chengarava cheShanghai, isu takanyanya kugadzira Zirconia Ceramics uye zvikamu zveAlumina Ceramic zvine makore gumi.
Iyo yakanyanya tembiricha yekudzivirira yezvimiro zveceramics inowanzova nani, kazhinji iri pasi pe800 ° C, uye tembiricha haina mhedzisiro pakusimba kweceramic zvinhu.Kuenzaniswa necovalent bond ceramics, ion-bonded ceramics ine hurombo hwakanyanya kupisa tembiricha.Kazhinji kutaura, mumhando yekushisa yakadzika, kutadza kwekuputsika kwekeramics maitiro asina kusimba, ndiko kuti, hapana kugadzirwa kwepurasitiki, uye iyo yekupedzisira dhizaini idiki kwazvo, uye inonzwa zvakanyanya kune hurema hudiki.Nekudaro, munzvimbo yepamusoro tembiricha, ceramics inogona kuburitsa diki deformation yepurasitiki isati yatyoka, iyo yekupedzisira dhizaini inowedzerwa zvakanyanya, uye kune hushoma hwemaitiro elastoplastic.Mukuwedzera, kunzwa kwesimba kune kukanganisa kunosiyana zvikuru.Muganhu uri pakati penzvimbo yakadzika tembiricha uye tembiricha yakakwira iyo inoburitsa iyi shanduko yemidziyo inowanzodaidzwa kunzi brittle ductility shanduko tembiricha.Iyo brittle ductility yekushandura tembiricha yakabatana zvakanyanya neiyo ceramic makemikari kuumbwa uye mhando yevalence bond.Inokodzera, asi zvakare inoenderana neiyo microstructure yekeramic, kuumbwa kwechikamu chemuganho wezviyo, kunyanya kuumbwa uye zvirimo muchikamu chegirasi rezviyo.Pakupisa kwakanyanya, pamusoro peiyo brittle ductility shanduko yekushisa, simba rezvakawanda zveceramic zvinhu zvinodzikira.Kune ion-bonded MgO ceramics, iyo brittle ductility shanduko tembiricha yakadzikira, uye simba rinodzikira nekuwedzera kwekushisa kunenge kubva mukamuri tembiricha.The brittle ductility transition tembiricha yeAl2O3 ingangoita 900°C, iyo brittle ductility transition tembiricha yehot-press sintered Si3N4 ingangoita 1200°C, uye SiC ceramics inowanzomira tembiricha yakakwira ye1600°C.
