Uburyo bwo Gukora Ibumba rya Karuboni ya Silicon

Uburyo bwo gukora Ceramics za Silicon Carbide: Incamake yuzuye

Imiterere yihariye ya kristale n'imiterere ya silicon carbide ceramics bigira uruhare mu miterere yayo myiza cyane. Ifite imbaraga nziza cyane, ubukana bwinshi cyane, idashira neza, idashonga neza, ihindagurika ry'ubushyuhe bwinshi ndetse irwanya ubushyuhe bwinshi. Iyi miterere ituma silicon carbide ceramics iba nziza cyane mu gukoresha mu gupima ikirere.

Gukora ibumba rya silicon carbide ubusanzwe bikoresha uburyo bukurikira:

1. Gutera imashini igabanya ubukana: Gutera imashini igabanya ubukana ni uburyo bukoreshwa cyane mu gukora impapuro zirinda amasasu za silikoni. Uburyo bworoshye, bworoshye gukoresha, bufite imikorere myiza kandi bukwiriye gukorwa buri gihe.

2. Gutera inshinge: Gutera inshinge bifite ubushobozi bwo guhuza ibintu neza kandi bishobora gukora imiterere n'imiterere bigoye. Ubu buryo ni ingirakamaro cyane cyane mu gukora ibice byihariye bya silikoni karubide.

3. Gukandagira mu buryo bukonje: Gukandagira mu buryo bukonje bikubiyemo gukoresha imbaraga zimwe ku mubiri w’icyatsi kibisi, bigatuma habaho gukwirakwira kw’ubucucike bumwe. Iri koranabuhanga rituma umusaruro w’ibicuruzwa urushaho kuba mwiza kandi rikwiriye gukorwamo ibikoresho bya silikoni bya karubide bifite imikorere myiza.

4. Gutera gel injection molding: Gutera gel injection molding ni uburyo bushya bwo gutera gel bungana n’ubugari. Umubiri w’icyatsi kibisi ukorwa ufite imiterere imwe kandi ukomeye cyane. Ibice bya ceramic biboneka bishobora gutunganywa n’imashini zitandukanye, ibyo bigatuma ikiguzi cyo gutunganya nyuma yo gutwika. Gutera gel injection molding bikwiriye cyane cyane mu gukora silicon carbide ceramics zifite imiterere igoye.

Bakoresheje ubu buryo bwo gushushanya, abakora bashobora kubona ibumba rya silicon carbide ryiza cyane rifite imiterere myiza ya mekanike na ballistic. Ubushobozi bwo gukora ibumba rya silicon carbide mu buryo butandukanye butuma habaho guhindura no kunoza ibisabwa byihariye mu buryo butandukanye.

Byongeye kandi, uburyo silicon carbide ceramics zihendutse mu kugabanya igiciro cyo hejuru byongera ubwiza bwazo nk'ibikoresho birwanya umupira w'amaguru. Uku guhuza imiterere myiza n'igiciro gikwiye bituma silicon carbide ceramics iba irushanwa rikomeye mu bushobozi bw'umubiri.

Mu gusoza, silicon carbide ceramics ni zo zikoreshwa cyane mu bikoresho bya ballistic bitewe n'imiterere yazo myiza n'uburyo bwo gushushanya butandukanye. Imiterere ya kristale, imbaraga, ubukana, kudashira, kudashonga, kudatwara ubushyuhe no kudashyuha kw'ibikomoka kuri silicon carbide ceramics bituma ziba amahitamo meza ku bakora n'abashakashatsi. Hamwe n'uburyo butandukanye bwo gukora, abakora bashobora guhindura silicon carbide ceramics kugira ngo ihuze n'ikoreshwa ryihariye, bigamije imikorere myiza no kurindwa. Ahazaza h'ibikomoka kuri silicon carbide ceramics ni heza kuko bikomeje gutera imbere no gukora neza mu bijyanye n'ibikoresho bya ballistic.

Ku bijyanye no kurinda ibyuma bikoreshwa mu gutwikira ibyuma, guhuza impapuro za polyethylene n'ibikoresho bikoreshwa mu gutwikira ibyuma bya keramike byagaragaye ko bigira akamaro cyane. Mu mahitamo atandukanye ya keramike ahari, karubide ya silikoni yakuruye abantu benshi haba mu gihugu no mu mahanga. Mu myaka ya vuba aha, abashakashatsi n'abakora ibikoresho bagiye bashakisha ubushobozi bwa keramike ya silikoni nk'ibikoresho birwanya ibyuma bikoreshwa mu gutwikira ibyuma bitewe n'imiterere yayo myiza kandi ihendutse.

Karubide ya silikoni ni ikintu kigizwe no gushyira hamwe tetrahedroni za Si-C, kandi gifite imiterere ibiri ya kristu, α na β. Ku bushyuhe buri munsi ya 1600°C, karubide ya silikoni iba mu ishusho ya β-SiC, kandi iyo ubushyuhe burenze 1600°C, karubide ya silikoni ihinduka α-SiC. Umugozi wa covalent wa karubide ya silikoni urakomeye cyane, kandi ushobora kugumana umugozi ukomeye cyane ndetse no mu bushyuhe bwinshi.
