Muraho, nshuti! Turi abanyamwugaifu y'ibyuma ikora mubushinwa. Dufite byinshiifu ya metallurgie gucumura ibice. Nkuruganda rukora ifu ya metallurgie nzakubwira uburyo bwo gutanga muri metallurgie yifu!
Uburyo bwo gucumura muri powder metallurgieihura nuruhererekane rwimpinduka zumubiri nubumara, nkamazi cyangwa guhumeka kama cyangwa guhindagurika, gukuraho gazi ya adsorption, kurandura imihangayiko, kugabanya ifu yifu ya oxyde igabanuka, kwimuka kwimibiri yimibumbe, kwimuka no gukura kwimbuto, bityo bigatuma intera ya kirisiti hagati yibice byiyongera, pore igabanuka cyangwa ikabura. Mugihe icyiciro cyamazi kigaragaye, gusesa no kugwa kwicyiciro gikomeye nabyo bizabaho. Izi nzira ntizifite imipaka isobanutse nizindi, ariko ziruzuzanya kandi zigira ingaruka. Usibye ubundi gucumura muri metallurgie, reaction yibicuruzwa byose bikozwe na powder metallurgie biragoye. Mu 1942, Umudage GF Schutig yakoresheje uburyo bw’ubushakashatsi bw’umubiri n’imiti kugira ngo apime ingaruka z’ubushyuhe bwo gucika ku mbaraga za electromotive, solubile, density, microstructure, mikoranike yumubiri wacumuye, maze asanga gucumura ari inzira igoye cyane. Mu 1949, GCKuczynski wo muri Amerika yize ku gucumura imipira y'ibyuma n'amasahani y'icyuma kandi yizera ko kwimuka kw'ibintu mu gihe cyo gucumura byakozwe ahanini no gukwirakwiza. Igikorwa cabo cyasunikishije kwiga inyigisho zo gucumura murwego rushya. Byinshi mubikorwa byakurikiyeho byubushakashatsi byibanze kuburyo bwo kwimuka kubintu mugihe cyo gucumura.
Muri rusange abantu bemeza ko hari uburyo butanu bwo kwimuka kwibintu mugihe cyo gucumura: gutembera neza cyangwa plastike, guhumeka no kwegeranya, gukwirakwiza ingano, gukwirakwiza imipaka, no gukwirakwiza hejuru. Iyo ibice bibiri bya sherfike bihuye byacumuye, gukura kwijosi rya radiyo X bishobora kuba bifitanye isano nigihe cyo gucumura t kuburyo bukurikira:
Uburyo bwo gucumura bugomba gukorerwa mu itanura ryogosha hamwe nikirere gikingira kugirango wirinde okiside yumubiri wacumuye cyangwa imiti mibi. Hariho ubwoko bwinshi bwitanura ryicyaha, rishobora gukoreshwa nkisoko yubushyuhe nka gaze gasanzwe, gaze, peteroli n amashanyarazi. Itanura ryo gushyushya amashanyarazi nubukungu kandi ryoroshye, byoroshye guhinduka no kugenzura. Ikirere gikunze gukoreshwa ni vacuum, argon, helium, azote, dioxyde de carbone nizindi myuka ya inert na hydrogène, kubora kwa ammonia, monoxide carbone, guhindura gaze naturel nibindi bigabanya imyuka.
Kugirango turusheho kunoza imikorere yibicuruzwa byacumuye nubunini nuburinganire bwukuri, akenshi birakenewe gukora shaping, kurangiza, guhagarika, kwibiza amavuta, gutunganya imashini, gutunganya ubushyuhe nibindi bikorwa byakurikiyeho.
