Umuyoboro w'icyuma wa Alumina Ceramic udashira: Imiterere, Inganda, n'Imikoreshereze yawo

Umuyoboro w'icyuma ukozwe muri aluminani umuyoboro w’ibice bivanze ukora neza cyane ukozwe mu gufata neza alumina ceramic ifite isuku nyinshi ku rukuta rw’imbere rw’umuyoboro w’icyuma. Ubusanzwe urwego rwa ceramic rugizwe na alumina itari munsi ya 95% (Al₂O₃), ifite ubukana bwa Rockwell buri hejuru ya HRA85 n’ubukana bwa Mohs buri hafi mu rwego rwa 9, ikaba iya kabiri nyuma ya diyama. Iyi nyubako ihuza ubukana bwinshi bwa alumina ceramic n’imbaraga n’ubukana bw’icyuma, bigatuma ikoreshwa mu bihe bikomeye byo kwangirika. Imiterere y’imiyoboro yubahiriza amahame y’ubuhanga kandi yemerera guhindura uburebure, umurambararo, n’uburyo bwo guhuza.

Uburyo bw'ibanze bwo gukora ni uburyo bwo gufatanya ibintu bifatanye n'uburyo bwo gusudira. Uburyo bwo gufatanya bukoresha kole ikomeye kandi idashyuha kugira ngo ifatanye neza amatafari ya alumina ceramic yakozwe mbere ku rukuta rw'icyuma cy'imbere, ikwiriye ahantu hashyushye hagati y'ubushyuhe buri hagati ya ≤150°C. Uburyo bwo gusudira bukoresha ubuhanga bwihariye bwo gusudira kugira ngo buhuze neza amatafari ya ceramic afite imyobo n'urukuta rw'icyuma cy'imbere, bigatuma habaho uburyo bwo guhuza icyuma hagati y'umuyoboro wa ceramic n'umuyoboro w'ibanze, butuma habaho guhangana n'ubushyuhe bwinshi (muri rusange ≤350°C) no gukurura cyane. Uburyo bwombi butuma umugozi wa ceramic ugenda neza kandi udafite imyobo, ufatanye neza n'umuyoboro w'ibanze.

Ibyiza by'ingenzi by'uyu muyoboro biri mu kudashira kw'amazi no kumara igihe kirekire ubikora. Mu gihe cy'akazi kamwe, kudashira kw'amazi kungana n'inshuro zirenga 20 z'imiyoboro isanzwe ya karuboni, bigabanya cyane ikiguzi cyo kuyisimbura no kuyitunganya. Byongeye kandi, itanga ubushobozi bwo kudashira kw'amazi n'ubuso bworoshye imbere, bigabanya ubwiyongere bw'ibikoresho no kudashira kw'amazi. Ikoreshwa cyane mu nganda nko gukora amashanyarazi, ibyuma, ubucukuzi bw'amabuye y'agaciro, no gutunganya imiti mu gutwara ifu, gucunga imyanda, no gutwara ibintu hakoreshejwe umwuka, bikemura neza ukwangirika gukabije kw'imiyoboro.
