2.5.Nano silicon nitride yakagadziridzwa epurasitiki optical tambo reel.
3. Nano titanium nitride (TiN)
3.1.Nano titanium nitride muPET kurongedza mabhodhoro uye epurasitiki yekurongedza zvinhu
a.Deredza tembiricha ye thermoplastic molding uye chengetedza simba ne30%.
b.Shade chiedza chero, kuvandudza kupenya uye kujeka kwechigadzirwa.
c.Wedzera tembiricha yekukanganisa kupisa kuti ive nyore kuzadza.
3.2.Kuvandudza mashandiro ePET engineering mapurasitiki.
3.3.Iyo yakakwira yekupisa emissivity coating inoshandiswa mumoto wekushisa wepamusoro uye kilns yekuchengetedza simba uye maindasitiri emauto.
3.4.Titanium nitride yakagadziridzwa jira rinoshanda.
4. Nano titanium carbide (TiC)
4.1.Inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvinopfekwa, maturusi ekucheka, molds, kunyungudutsa simbi crucibles uye mamwe akawanda minda.
4.2.Kuoma kwe nano titanium carbide (TiC) inofananidzwa nedhaimondi rekugadzira, iyo inovandudza zvakanyanya kukuya, kukuya uye kupera kwepamusoro.
4.3.Metal surface coating material.
5. Nano-zirconia/zirconium dioxide (ZrO2)
ZrO2 nano powder chinhu chakakosha chekugadzirwa kwekeramics yakakosha, inogona kushandiswa kugadzira zvakasiyana-siyana zvekugadzira uye zvinoshanda.
5.1.Phase shanduko yakaoma ceramics
Iyo brittleness yezvinhu zveceramic inodzikamisa kushandiswa kwayo, uye nano ceramics inzira yakakosha yekugadzirisa nyaya.Ongororo dzinoratidza kuti maceramics anogona kuomeswa nekushandiswa kweZrO2 tetragonal phase kune monoclinic phase kugadzira microcracks uye kusara kunetseka.Iyo tembiricha yekuchinja inogona kudonha pasi pekamuri tembiricha kana ZrO2 zvimedu zviri pa nanoscale.Naizvozvo, nano ZrO2 inogona kuvandudza zvakanyanya tembiricha yekamuri simba uye kushushikana kwakanyanya chinhu chekeramics, nekudaro ichiwedzera kuoma kwemakeramiki.
5.2.Ceramics yakanaka
Nano zirconia inogona kuvandudza zvakanyanya tembiricha yekamuri simba uye kushushikana kwakanyanya chinhu chekeramics, nekudaro ichiwedzera kuoma kweceramics.Iyo composite bioceramic zvinhu zvakagadzirirwa nano ZrO2 ine yakanaka mechaniki zvivakwa, kugadzikana kwemakemikari uye biocompatibility, uye imhando yezvakasanganiswa bioceramic zvinhu zvine tarisiro huru yekushandisa.
5.3.Refractory
Zirconia ine yakakwira yekunyungudika, yakaderera thermal conductivity uye yakagadzikana makemikari ehupfumi, saka inowanzoshandiswa sechinhu chinoramba.Zvakanakira zvinhu zvinoramba zvakagadzirirwa ne nano zirconia zvakanyanya kukosha, senge tembiricha yakakwira (tembiricha yekushandisa inogona kusvika 2200 ℃), simba rakakura, kuita kwakanaka kwekushisa kwekushisa uye kugadzikana kwemakemikari, uye inonyanya kushandiswa munharaunda nekushanda. tembiricha iri pamusoro pe2000 ℃.
5.4.Zvinhu zvisingapfeki
Kuwedzera 5% nano chiyero Al2O3 poda kune yakajairwa Al2O3 ceramics inogona kuvandudza kuoma kwemakeramiki uye kuderedza sintering tembiricha.Nekuda kwe superplasticity ye nano-Al2O3 poda, inogadzirisa zvikanganiso zveyakadzika tembiricha brittleness iyo inodzikamisa mashandisirwo ayo, saka inoshandiswa zvakanyanya mukupisa kwakadzika kwepurasitiki alumina ceramics.Inogona kuiswa kune inoshanda maceramics, zvimiro zveceramics, yakajeka ceramics, textile ceramics.
Nano zinc oxide chinhu chakakosha mbishi checeramic kemikari flux, kunyanya mukuvaka ceramic madziro uye pasi tile glaze uye yakaderera tembiricha yemagineti.
