Hauvhigh -kub muaj ib puag ncig, qhov loj tshaj kev sib tw engineers fim tsis yog qhov kub ntawm lawv tus kheej, tab sis scaling (oxidative flakes). Thaum cov txheej txheem alloys ua haujlwm ntawm qhov kub thiab txias nruab nrab700℃thiab 900 degree, oxygen reacts nrog hlau nto, tsim ib txheej oxide brittle.
Cov phom sij ntawm kev ntsuas muaj xws li:
** Phab ntsa thinning:**Nruam oxidation ua rau cov hlau poob sai, cuam tshuam cov txheej txheem kev ncaj ncees ntawm cov kav dej thiab cov kav dej rauv.
* ** Cov khoom paug: **Flaked oxide nplai nyob ntawm cov khoom ua haujlwm (tshwj xeeb tshaj yog nyob rau hauv semiconductor, ceramics, lossis iav industries), uas ua rau cov khoom seem siab.
* ** Ncua sij hawm downtime:**Thaum cov yeeb nkab phab ntsa tuab tshaj qhov txwv kev nyab xeeb, tag nrho cov kab ke yuav tsum raug kaw kom raug nqi hloov.
Peb oxidation -resistantGH3030 cev, tsim tshwj xeeb los daws qhov teeb meem no, tiv thaiv lub voj voog tsis zoo no. Raws li cov chaw tsim khoom Tier 1, peb cov tubing tsim ib tus kheej - kho qhov thaiv kev tiv thaiv, ua kom muaj kev lag luam- qib durability txawm nyob rau hauv cov kev xav tau tshaj plaws.

1. Corrosion Resistance Qhov Zoo ntawm GH3030
Qhov kev ua tau zoo tshaj ntawm GH3030 (Ni-75 sib npaug alloy) stems los ntawm nws cov ntsiab lus chromium siab (19-22%). Thaum qhov kub thiab txias, chromium tsiv mus rau saum npoo, tsim ib txheej tuab thiab nplaum heev Cr₂O₃ (chromium oxide) txheej.
Tsis zoo li cov ntxeem tau oxides ntawm cov hlau tsis huv, cov txheej txheem zoo tshaj no muaj cov yam ntxwv hauv qab no:
Muaj zog Adhesion:Nws tsis tev tawm thaum lub sij hawm thermal cycling ceev (cua sov thiab txias).
Dej impermeability:Nws ua raws li cov txheej txheem tiv thaiv, tiv thaiv cov pa oxygen los ntawm kev nkag mus tob rau hauv cov nickel substrate.
Kev ruaj ntseg zoo:Nws tuav cov txheej txheem kev ncaj ncees txawm nyob rau ntawm qhov kub thiab txias mus txog 800℃(1472℃F).

2. Kev sib piv ntawm GH3030 thiab 310S Stainless Hlau
Txawm hais tias 310S feem ntau suav hais tias yog "kub resistant", GH3030 muaj kev txhim kho tseem ceeb nyob rau hauv ntev -lub sij hawm oxidation stability.
Oxidation Rate Sib Piv (Kev Ntsuas ntawm 800℃hauv Cua rau 1000 Teev):
| Khoom Qib | Qhov hnyav nce / poob (mg / cm²) | Scaling Observation | Muaj Kev Txiav Txim Siab |
| Stainless hlau 310S | +1.8 rau +2.5 | Nruab nrab scaling; pom flaking tom qab lub voj voog. | Zoo rau cov cua sov yooj yim, nquag ua kom muaj kuab paug. |
| GH3030 (Alloy 75) | +0.4 rau +0.8 | Tsawg qhov hnyav hloov; oxide txheej tseem nyob tsis tu ncua. | Txaus siab rau Aerospace & Precision Furnaces. |
| Stainless hlau 304 | > 10.0 | Loj scaling thiab puas hlau poob. | Tsis pom zoo rau siab -temp service. |

FAQ
Q1: Thaum twg qhov kub ntawm oxidation ntawm GH3030 ua hnyav?
A: GH3030 yog qhov ruaj khov heev mus txog800 degree. Tshaj li 900 degree, oxidation tus nqi nce, thiab rau kev siv tsis tu ncua mus txog 1000 degree, koj tuaj yeem pom qee qhov tuab ntawm cov nplai, txawm tias nws tseem nyob deb tshaj rau cov hlau tsis muaj steel.
Q2: Puas yog oxide txheej ua paug rau kuv lub qhov cub "chav huv" ib puag ncig?
A: Tsis yog. Ib qho ntawm cov laj thawj tseem ceeb uas cov neeg siv khoom hloov kho mus rau GH3030 yog nws"Tsis yog-Scaling"vaj tse. Cov oxide txheej yog "nruj," txhais tau tias nws nyob ntawm cov hlau ntau dua li flaking tawm rau hauv koj qhov chaw tsim khoom.
Q3: Puas yog vuam cuam tshuam rau oxidation tsis kam?
A: Yog tias welded nrog cov muab tub lim kom raug (xws li ERNiCr-3), thaj tsam weld yuav muaj ze li ntawm oxidation tsis kam rau lub hauv paus hlau, ua kom muaj kev sib haum xeeb.Cov khoom siv lub neej voj voog.
Q4: Koj puas tuaj yeem muab cov raj nrog polished nto kom txo oxidation ntxiv?
A: Yog. Peb muabBright Annealedlos yog polished finishes uas muab ib tug smoother nto rau ib tug txawm ntau uniform tiv thaiv oxide zaj duab xis.
