Seramik malzemelerin haz\u0131rlanmas\u0131 s\u00fcrecinde, tozun haz\u0131rlanmas\u0131 \u00e7ok \u00f6nemli bir ba\u011flant\u0131d\u0131r ve tozun performans\u0131 do\u011frudan bitmi\u015f seramik \u00fcr\u00fcn\u00fcn performans\u0131n\u0131 belirler. Tozun performans\u0131 temel olarak tozun par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131na ve mikroskobik morfolojisine ba\u011fl\u0131d\u0131r.<\/p>\n

Tozun par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131 esas olarak seramik malzemelerin tane boyutunu ve sinterleme performans\u0131n\u0131 etkiler. Ara\u015ft\u0131rmac\u0131lar, tozun par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131n\u0131n al\u00fcmina seramik malzemenin yo\u011funlu\u011fu \u00fczerindeki etkisini inceledi ve sonu\u00e7lar, geni\u015f veya dar bir par\u00e7ac\u0131k kullan\u0131m\u0131na bak\u0131lmaks\u0131z\u0131n yakla\u015f\u0131k %99 yo\u011funlu\u011fa sahip al\u00fcmina serami\u011fin haz\u0131rlanabilece\u011fini g\u00f6sterdi. boyut da\u011f\u0131t\u0131m tozu ve tane boyutu korunabilir. Bununla birlikte, yakla\u015f\u0131k 1 \u03bcm’de, daha geni\u015f bir par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131, tozla s\u0131k\u0131\u015ft\u0131r\u0131lm\u0131\u015f ham g\u00f6vdenin yo\u011funlu\u011funu art\u0131rabilir ve malzemenin daha d\u00fc\u015f\u00fck bir b\u00fcz\u00fclme oran\u0131yla bir yo\u011funla\u015ft\u0131rma i\u015flemine tabi tutulmas\u0131n\u0131 sa\u011flayabilir. Bunun ana nedeni, geni\u015f bir par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131na sahip olan tozdaki b\u00fcy\u00fck par\u00e7ac\u0131klar\u0131n, kal\u0131plama i\u015flemi s\u0131ras\u0131nda ince par\u00e7ac\u0131klarla doldurulan daha fazla bo\u015fluk olu\u015fmas\u0131d\u0131r.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar bu konuda daha derinlemesine bir \u00e7al\u0131\u015fma y\u00fcr\u00fctt\u00fcler. Sinterlemeyi \u00fc\u00e7 a\u015famaya ay\u0131rd\u0131lar: ba\u015flang\u0131\u00e7, orta ve ge\u00e7 a\u015famalar. Daha geni\u015f par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131na sahip toz, ham g\u00f6vdenin yo\u011funlu\u011funu artt\u0131r\u0131r ve sinterlemenin erken a\u015famas\u0131nda serami\u011fin yo\u011funla\u015ft\u0131rma h\u0131z\u0131n\u0131 h\u0131zland\u0131r\u0131r. Ek olarak, sinterlemenin orta a\u015famas\u0131nda, geni\u015f par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131na sahip toz, tane b\u00fcy\u00fcme h\u0131z\u0131n\u0131 art\u0131r\u0131r ve malzemedeki kapal\u0131 izolasyon g\u00f6zenekleri daha b\u00fcy\u00fck gran\u00fcler matrise g\u00f6m\u00fcl\u00fcr, bu nedenle daha iyi sinterlenebilirli\u011fe sahiptir ve sinterlemenin sonraki a\u015famas\u0131nda y\u00fcksek sinterleme h\u0131z\u0131. Bununla birlikte, daha geni\u015f bir par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131, malzemenin yerel par\u00e7ac\u0131klar\u0131n\u0131n birikmesi nedeniyle yo\u011funla\u015ft\u0131rmada bir farka yol a\u00e7acakt\u0131r. Par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131 belli bir boyutu a\u015ft\u0131\u011f\u0131nda bile sinterlenmi\u015f b\u00fcnyenin tane boyutu \u00e7ok b\u00fcy\u00fck olacak ve g\u00f6zenek yap\u0131s\u0131 daha iri hale gelecektir. Y\u00fcksek yo\u011funluklu al\u00fcmina seramik elde etmek i\u00e7in, kal\u0131plama ve sinterleme y\u00f6ntemlerinin se\u00e7imi, toz partik\u00fcl boyutu da\u011f\u0131l\u0131m\u0131n\u0131n se\u00e7iminde kilit rol oynar. Bu nedenle, tozun par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131 seramik malzemenin yo\u011funlu\u011fu \u00fczerinde b\u00fcy\u00fck bir etkiye sahiptir ve bu da serami\u011fin termal iletkenli\u011fini belirler.<\/p>\n

D\u00fczenli \u015fekle sahip al\u00fcmina tozu, sinterleme i\u015flemi s\u0131ras\u0131nda seramik malzemelerin performans\u0131 \u00fczerinde b\u00fcy\u00fck bir etkiye sahip olacakt\u0131r. Ara\u015ft\u0131rmac\u0131lar, makul par\u00e7ac\u0131k boyutuna ve par\u00e7ac\u0131k derecesine sahip tozun, toza bir ba\u011flay\u0131c\u0131 eklenerek gran\u00fcl haline getirilebilece\u011fine inan\u0131yor. Daha ak\u0131\u015fkan hale getirmek, sonraki kal\u0131plama ve sinterleme \u00fczerinde olumlu bir etkiye sahip olacakt\u0131r. Bunlar\u0131n aras\u0131nda gran\u00fclasyon i\u015flemi, tozun ba\u011flay\u0131c\u0131n\u0131n etkisi alt\u0131nda k\u00fcresel bir \u015fekil olu\u015fturmas\u0131n\u0131 sa\u011flamakt\u0131r; bu da dolayl\u0131 olarak k\u00fcresel al\u00fcminan\u0131n kal\u0131plama ve sinterleme i\u015flemi s\u0131ras\u0131nda serami\u011fin yo\u011funlu\u011funu iyile\u015ftirmede olumlu bir rol oynad\u0131\u011f\u0131n\u0131 g\u00f6sterir.<\/p>\n

Bu nedenle, tozun performans\u0131n\u0131n (morfoloji ve par\u00e7ac\u0131k boyutu) seramik sinterleme performans\u0131n\u0131 etkiledi\u011fi bulunabilir, bu da serami\u011fin termal iletkenli\u011finin ondan ayr\u0131lamaz oldu\u011fu anlam\u0131na gelir. Kal\u0131plama ve sinterlemeden sonra pul tozu daha d\u00fc\u015f\u00fck yo\u011funlu\u011fa ve daha y\u00fcksek g\u00f6zeneklili\u011fe sahiptir. , ara\u015ft\u0131rmac\u0131lar \u00f6n olarak termal iletkenli\u011finin y\u00fcksek olmad\u0131\u011f\u0131n\u0131 tahmin ettiler; ve k\u00fcresel al\u00fcmina tozu, y\u00fcksek yo\u011funluklu \u015feffaf seramikler \u00fcretebilir, bu nedenle termal olarak iletken seramikler haz\u0131rlamak i\u00e7in k\u00fcresel toz kullanman\u0131n uygun bir se\u00e7im oldu\u011fu yarg\u0131s\u0131na var\u0131labilir.<\/p>\n","protected":false},"excerpt":{"rendered":"
