Ukuqukumbela
I-Wonder Garden ibonelele ngekhatriji yeceramic yeZirconia (Zirco™) kunye nekhatriji yentsimbi esemgangathweni yophando lwethekhnoloji yobushushu bomoya.Ukuphonononga ukuqina kunye nokuthotywa kwe-thermal yeesampulu, i-Aliovalents Material Research isebenzise i-pycnometry, i-x-ray diffraction, i-electron microscopy yokuskena kunye ne-energy dispersive spectroscopy kwiisampulu ezohlukeneyo ukusuka kwi-pristine ukuya kokwehla (300 °C kunye ne-600 °C).Ukuncipha koxinaniso kubonise ukwanda komthamo wesampulu yobhedu kwi-600 ° C, ngelixa isampuli ye-ceramic ayizange ibonise naluphi na utshintsho olubalulekileyo ekuxininiseni.
Ubhedu olusetyenziswa njengentsimbi yeziko-isithuba lufumene i-oxidation ebalulekileyo ngexesha elifutshane, xa kuthelekiswa nesampuli ye-ceramic.Iziko le-ceramic-post lihlala licocekile ngenxa yendalo ephezulu yekhemikhali engashukumiyo ye-ionic bonding yayo.Ukuskena imakroskopu ye-electron emva koko kwasetyenziswa ukufumana imifanekiso enesisombululo esiphezulu kwi-microscale ukuchonga naluphi na utshintsho lomzimba.Umphezulu wobhedu owawunganyangeki kwi-corrosion kwaye wawuxutywe ngokupheleleyo.Ukwanda okubonakalayo kuburhabaxa bomphezulu kwenzeke ngenxa ye-oxidation, esebenza njengeendawo ezintsha ze-nucleation ukwenzela umhlwa ongakumbi owenze mandundu ukuthotywa.
Kwelinye icala, iisampulu zeZirconia zihlala zingaguquguquki kwaye zingasetyenziselwa izicelo zobushushu obuphezulu.Oku kubonisa ukubaluleka kokudibanisa imichiza ye-ionic kwi-Zirconia vs i-metallic bonding kwindawo ye-Brass center.Imephu esisiseko yeesampulu ibonise umxholo ophezulu we-oksijini kwiisampuli zetsimbi ezonakeleyo ezihambelana nokubunjwa kwee-oxides.
Idatha eqokelelweyo ibonisa ukuba isampuli ye-ceramic izinzile kakhulu kumaqondo obushushu aphakamileyo apho iisampuli zavavanywa khona.
