Umuvuduko wa Atmospheric wacumuyesilicon karbidentagikoreshwa gusa nkigisebo, ahubwo nibindi byinshi nkibikoresho bishya, kandi bikoreshwa cyane mubicuruzwa byikoranabuhanga buhanitse, nkibumba ryakozwe nasilicon karbideibikoresho. None ni izihe nyungu esheshatu z'umuvuduko w'ikirere uhindura silicon karbide no gukoresha ceramics ya silicon karbide?
Ibyiza bitandatu byumuvuduko wikirere byacumuyesilicon karbideibikoresho:
1. Ubucucike buke
Ibikoresho bya silicon karbide bifite ubucucike buri munsi yicyuma, bigatuma igikoresho cyoroha.
2. Kurwanya ruswa
Carbideibikoresho bifite aho bishonga cyane, inertia ya chimique, kurwanya ubushyuhe bwumuriro, karbide ya silicon ikoreshwa mubikoresho byo gutwika, itanura rya ceramic, karubide ya karubide, irashobora gukoreshwa mu nganda zo gushonga no gushonga hamwe n’itanura rya veritiki ya silinderi, amatafari, aluminium electrolytique selile, tungsten , itanura rito nibindi bicuruzwa bya silicon carbide ceramic.
3, ubushyuhe bwo hejuru, coefficente yo kwagura ubushyuhe iragabanuka
Ibikoresho bya karubide ya silicon bikozwe mubushyuhe bwinshi. Mubihe bimwe byubushyuhe bwo hejuru, ibikoresho bisaba imbaraga zo gutunganya no gutunganya neza ko silicon karbide ceramics ishobora kugeraho irakenewe. Ubushyuhe bwo hejuru bwa karibide ya silicon ni 800, naho ubushyuhe bwibyuma ni 250. Kubara neza, impuzandengo yo kwagura ubushyuhe bwa carbide ya silicon iri hagati ya 25 ~ 1400 ni 4.10-6 / C. Coefficient yo kwagura amashyuza ya karubide ya silicon irapimwa, kandi ibisubizo byerekana ko amafaranga ari make cyane ugereranije nayandi mabi ndetse nubushyuhe bwo hejuru. Carbide ya silicon yamenetse munsi yumuvuduko wikirere
4, ubushyuhe bwinshi
Ubushyuhe bwumuriro wibikoresho bya silicon karbide ni muremure, nikindi kintu cyingenzi kiranga ibintu bifatika bya karubide ya silicon. Ubushyuhe bwumuriro wa karubide ya silicon irarenze cyane iyindi mashanyarazi na abrades, hafi inshuro 4 za corundum. Carbide ya Silicon ifite coefficient nkeya yo kwagura ubushyuhe hamwe nubushyuhe bukabije bwumuriro, bityo igihangano kizagerwaho nubushyuhe buke bwumuriro mugihe cyo gushyushya no gukonja. Niyo mpamvu ibice bya SiC birwanya cyane guhungabana.
5, imbaraga za mashini nyinshi, gukomera kwiza
Imbaraga zumukanishi wibikoresho bya silicon karbide ni ndende cyane, birinda guhindura ibintu. Carbide ya Silicon ifite imbaraga zo gukanika kuruta corundum.
6, gukomera no kwambara birwanya
Ubukomezi bwibikoresho bya karubide ya silicon ni ndende cyane, kandi ubukana bwikinyuranyo cya Moss ni 9.2 ~ 9,6, bukurikira kabiri bwa karubide ya diyama na tungsten. Ugereranije nibikoresho byuma byuma, bitanga ubukana bwinshi, coefficente nkeya yo guterana, ugereranije ugereranije hasi, ubukana buto bwo hejuru hamwe no kwihanganira kwambara neza nta mavuta. Byongeye kandi, irwanya ibintu byo hanze, itezimbere kwihanganira ubuso. Carbide ya silicon yamenetse munsi yumuvuduko wikirere
Gukoresha umuvuduko wikirere wacumuye silicon karbide ceramics
1, silicon karbide yibikoresho byububiko bwihariye
Ibikoresho bya karuboni ya silicon ni ibikoresho bifite ubukana bwinshi kandi bidahenze, bishobora kubyara ibicuruzwa bya karuboni ya silikoni, nka kashe ya karubide ya silikoni, amaboko ya silikoni ya karubide, ibyapa byerekana amasasu ya silicon, imyirondoro ya karibide, n'ibindi, bishobora gukoreshwa kuri kashe ya mashini kandi pompe zitandukanye. Carbide ya silicon yamenetse munsi yumuvuduko wikirere
2, zirconia ibikoresho byumusemburo udasanzwe
Ceramic ya Zirconia ifite ubushobozi bwa ionic itwara neza, imiti ihamye kandi itajegajega, kandi yabaye ibikoresho byizwe cyane kandi bikoreshwa na electrolyte. Mugutezimbere uburyo bwo gukora firime ya zirconi ishingiye kuri electrolyte, kugabanya ubushyuhe bwakazi nigiciro cyo gukora ibyo bikoresho, no guharanira kugera mu nganda nabyo ni icyerekezo cyingenzi cyubushakashatsi buzaza.
