Wambare isahani idashobora kwihanganira

Kwambara icyuma cyihanganira icyuma kigizwe nicyuma gike cya karuboni nkeya hamwe nicyuma cyihanganira kwambara.Umuti wihanganira kwambara ni 1/3 ~ 1/2 cyubugari bwuzuye.Mugihe cyo gukora, matrix itanga ibintu byuzuye nkimbaraga, ubukana hamwe na plastike kugirango irwanye imbaraga ziva hanze, kandi igipande kidashobora kwangirika gitanga ibintu birwanya kwambara byujuje ibisabwa mubikorwa byakazi.

Isahani idashobora kwangirika isahani ihujwe hagati yicyuma kidashobora kwangirika hamwe na substrate.Binyuze mubikoresho bidasanzwe hamwe nuburyo bwo gusudira bwikora, ubukana bwo hejuru bwikingira burinda gusudira insinga irasudira neza kuri substrate.Umubare wibice bigize ibice ni kimwe kugeza kuri bibiri cyangwa ndetse nuburyo bwinshi.Mugihe cyo guhuriza hamwe, ibice bimwe bihinduranya bigaragarira bitewe nigipimo gitandukanye cyo kugabanuka, ibyo bikaba aribintu bidasanzwe biranga icyuma cyihanganira kwambara.

Imyenda idashobora kwangirika igizwe ahanini na chromium alloy, nibindi bikoresho bivangwa nka manganese, molybdenum, niobium na nikel nabyo byongeweho.Carbide muburyo bwa metallografiya ikwirakwizwa muburyo bwa fibre, kandi icyerekezo cya fibre ni perpendicular kubuso.Micro ikomeye ya karbide irashobora kugera hejuru ya hv1700-2000 naho gukomera hejuru birashobora kugera kuri HRC58-62.Amavuta ya karubide afite imbaraga zikomeye mubushyuhe bwinshi, agumana ubukana bwinshi, kandi afite imbaraga zo kurwanya okiside.Birashobora gukoreshwa mubisanzwe muri 500 ℃.

Igice cyihanganira kwambara gifata imiterere yumuyoboro muto (2.5-3.5mm), umuyoboro mugari (8-12mm), umurongo (s, w), nibindi;Igizwe ahanini na chromium alloy nibindi bikoresho bivangwa nka manganese, molybdenum, niobium, nikel na boron.Carbide muburyo bwa metallografiya ikwirakwizwa muburyo bwa fibre, kandi icyerekezo cya fibre ni perpendicular kubuso.Ibirimo karbide ni 40-60%, microhardness irashobora kugera kuri hv1700, kandi ubukana bwubuso bushobora kugera kuri HRC58-62.

Igipimo cyo gusaba

Kwambara icyuma cyihanganira icyuma gifite imbaraga zo kurwanya no gukora neza.Irashobora gukata, kugororwa no gusudira.Irashobora guhuzwa nizindi nzego mugusudira, gucomeka gusudira no guhuza.Nibitwara igihe kandi byoroshye mugikorwa cyo kubungabunga.Ikoreshwa cyane muri metallurgie, amakara, sima, ingufu z'amashanyarazi, ikirahure, ubucukuzi bw'amabuye y'agaciro, ibikoresho byo kubaka, amatafari na tile n'inganda.Ugereranije nibindi bikoresho, bifite imikorere ihenze cyane, Byatoneshejwe ninganda ninshi ninganda.
