Gutera ibyuma bya aluminiyumu bya Matrix Composites

(1) Ibiranga ubutare bw'icyuma gikozwe muri aluminiyumu birimo cyane cyane uduce duto (harimo n'udusahuzi) n'udusahuzi twongera imbaraga. Ibikoresho bikoreshwa mu gushimangira ahanini birimo B, CB, SiC, nibindi.

Iyo ibyuma bya aluminiyumu bivanze kandi bigashyuha, matrix Al biroroshye kuyikoresha hamwe n’icyiciro cyo gushimangira, nko gukwirakwira vuba kwa Si mu cyuma cyo gucukura ku cyuma cyo hasi no kurema urwego rwo gucukura rudafite ubushyuhe. Bitewe n’itandukaniro rinini mu buryo bwo kwaguka hagati ya Al n’icyiciro cyo gushimangira, gushyushya nabi ibyuma bizatera ubushyuhe ku gice cyo hagati, byoroshye gutera gucika kw’ingingo. Byongeye kandi, ubushyuhe hagati y’icyuma cyo gucukura n’icyiciro cyo gushimangira ni bubi, bityo ubuso bwo gucukura bw’icyuma cyo gucukura bugomba gutunganywa cyangwa hagakoreshwa icyuma cyo gucukura, kandi icyuma cyo gucukura gikoreshwa uko bishoboka kose.

(2) Ibikoresho byo gusiga icyuma n'ibikoresho bya aluminium B cyangwa SiC bishobora gusigwa icyuma, kandi gutunganya ubuso mbere yo gusudira bishobora gukorwa hakoreshejwe gusya impapuro z'umucanga, gusukura uburoso bw'insinga, gukaraba alkali cyangwa gusiga nickel nta amashanyarazi (ubugari bwa 0.05mm). Icyuma cyuzuza ni s-cd95ag, s-zn95al na s-cd83zn, bishyushywa n'urumuri rworoshye rwa oxyacetylene. Byongeye kandi, imbaraga nyinshi zo gufatanya zishobora kuboneka hakoreshejwe gusya icyuma hakoreshejwe solder ya s-zn95al.

Gutera icyuma gifunga icyuma gikoresha icyuma gifunga icyuma gikoreshwa mu guhuza ibyuma bivanze bya aluminium bya Short Fiber Reinforced 6061. Mbere yo gutera icyuma gifunga, ubuso bugomba gusya hakoreshejwe impapuro 800 zisanzwe nyuma yo gusya, hanyuma bugashyirwa mu itanura nyuma yo gusukura acetone hakoreshejwe ultrasound. Ibyuma bifunga icyuma gikoresha icyuma gifunga icyuma cya Al Si ahanini bikoreshwa. Kugira ngo hirindwe ko Si ikwirakwira mu cyuma cy'ibanze, hashobora gusigwa urwego rw'icyuma gifunga icyuma gifunga icyuma gifunga icyuma gifunga icyuma, cyangwa hagatoranywa icyuma gifunga icyuma gifite imbaraga nke zo gutera icyuma. Ubushyuhe bushongesha icyuma gifunga icyuma ni 554 ~ 572 ℃, ubushyuhe bushobora kuba 580 ~ 590 ℃, igihe cyo gutera icyuma ni iminota 5, kandi imbaraga zo gukata icyuma zirenze 80mpa.

Ku bijyanye n'ibice bya aluminium bya graphite reinforced particles, gukoresha brazing mu itanura ririnda umwuka ni bwo buryo bwiza cyane muri iki gihe. Kugira ngo hongerwe uburyo bwo kumena, hagomba gukoreshwa Al Si solder irimo Mg.

Kimwe no mu gufunga icyuma gikozwe muri aluminiyumu, ubushobozi bwo kunywesha bw'ibice bya aluminiyumu bishobora kunozwa cyane hakoreshejwe umuyaga wa mg cyangwa Ti suction no kongeramo ingano runaka ya Mg.
