Ubusanzwe ubusembwa bwibituba bidafite kashe

Ubusanzwe ubuso bwinyuma bwumuyoboro utagira kashe (smls):

1. Inenge
Ikwirakwizwa ridasanzwe: Niba icyapa kibumbabumbwe gikomeje kuba hejuru yubuso bwa plaque ikomeza, inenge zimbitse zizagaragara hejuru yinyuma yigitereko kizunguruka, kandi zizagabanywa igihe kirekire, kandi "bloks" zizagaragara mubice bimwe byubuso. .Ubujyakuzimu bwikubye bwa tube hafi ya 0.5 ~ 1mm, naho icyerekezo cyo kugabura ni 40 ° ~ 60 °.

2. Inenge nini
Ikwirakwizwa rirerire: Inenge za Crack hamwe nubunini bunini bugaragara bigaragara hejuru yicyapa gikomeza, kandi bigabanywa igihe kirekire.Ubwinshi bwimbitse hejuru yubuso bwibyuma bidafite ingero zingana na mm 1 kugeza 10.

3. Inenge ntoya
Iyo ugerageza imiyoboro idafite ibyuma, hari ubusembwa bwubuso kurukuta rwinyuma rwumubiri wumuyoboro udashobora kugaragara n'amaso yambaye ubusa.Hariho utunenge duto duto twinshi hejuru yubuso bwicyuma kitagira ikizinga, ubujyakuzimu bwimbitse bugera kuri 0.15mm, hejuru yumuyoboro wicyuma utagira ikizinga utwikiriwe nigice cya oxyde yicyuma, kandi hariho decarburisation munsi ya oxyde yicyuma, ubujyakuzimu ni 0.2mm.

4. Inenge igaragara
Hano hari inenge igaragara kumurongo winyuma wicyuma kitagira icyuma, kandi ibiranga umwihariko ni ubujyakuzimu butagaragara, gufungura ubugari, hepfo igaragara, nubugari buhoraho.Urukuta rw'inyuma rw'ibice byambukiranya umuyoboro w'icyuma udafite icyerekezo urashobora kugaragara ufite ibishushanyo bifite ubujyakuzimu bwa <1mm, biri mu buryo bwa shobora.Nyuma yo kuvura ubushyuhe, habaho okiside na decarburisation kumpera yumuringoti.

5. Inenge
Hano hari inenge zidafite umwobo hejuru yinyuma yicyuma kitagira icyuma, gifite ubunini nubuso butandukanye.Nta okiside, decarburisation, hamwe no guteranya hamwe no kwinjiza hafi y'urwobo;imyenda ikikije urwobo iranyeganyezwa munsi yubushyuhe bwinshi, kandi ibimenyetso bya plastiki ya rheologiya bizagaragara.

6. Kuzimya
Kuzimya no kugabanya ubushyuhe bikorerwa kumuyoboro wicyuma udafite ikidodo, kandi ibice byiza birebire bigaragara hejuru yinyuma, bigabanywa mumirongo ifite ubugari runaka.

Ubusanzwe ubuso bwimbere bwimbere bwigituba kitagira kashe:

1. Inenge ya convex
Ibiranga Macroscopique: Urukuta rwimbere rwumuyoboro wicyuma rutagabanije gukwirakwiza utuntu duto duto duto twa convex, kandi uburebure bwiyi nenge ntoya ni 0.2mm kugeza kuri 1mm.
Ibiranga Microscopique: Hariho urunigi rumeze nk'umukara-imvi zometse ku murizo, hagati no kuzengurutse uruzitiro rwa convex ku mpande zombi z'urukuta rw'imbere rw'ibice byambukiranya umuyoboro w'icyuma.Ubu bwoko bwurunigi rwumukara burimo calcium aluminate hamwe na oxyde nkeya (oxyde de fer, okiside silicon, oxyde ya magnesium).

2. Inenge igororotse
Ibiranga Macroscopique: Inenge zo mu bwoko bugororotse zigaragara mu miyoboro idafite ibyuma, ifite ubujyakuzimu n'ubugari runaka, bisa n'ibishushanyo.

Ibiranga Microscopique: Igishushanyo ku rukuta rwimbere rwambukiranya igice cyumuyoboro wicyuma kidafite icyerekezo kiri muburyo bwa groove ifite ubujyakuzimu bwa cm 1 kugeza kuri 2.Oxidative decarburisation ntabwo igaragara kumpera ya groove.Tissue ikikije groove ifite ibiranga rheologiya yicyuma no gukuramo ibintu.Hazabaho microcrack kubera ubunini bwa extrusion mugihe cyo gupima.
