Yuav ua li cas kom tshem tau xeb ntawm cov txee muaj txee？

Qhov zoo ntawm kev lag luam txee rau laj kab yog ncaj qha ntsig txog kev nyab xeeb ntawm cov khoom siv hauv cov rooj sib tham, yog li nws yog qhov tseem ceeb heev uas yuav tsum xaiv ib lub txee rau kev lag luam kaw tsis muaj xeb. Yog li yuav ua li cas koj derust kev lag luam txee ntsuas thaum koj siv lub ntsuas phoo?

Thaum paub qhov txawv seb cov hlau hauv cov txee ntim kev lag luam tau xeb, nws yog qhov tsim nyog yuav tsum paub qhov sib txawv ntawm cov hlau tsis xeb los ntawm qhov chaw tsis huv los ntawm cov hlau ua thiab kev puas tsuaj ntawm kev nkag mus txhua hnub thiab tshem tawm. Feem ntau, nws tuaj yeem pom qhov txawv los ntawm lub khob iav dua.

Txij li cov hlau xeb feem ntau xoob thiab cov khoom ntxeem tau txuas nrog cov hlau txheej ntawm chaw tsim khoom raug kaw, nws tsis ruaj khov kho rau lub hauv paus hlau. Nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, qhov kev hloov kho yog tev tawm los ntawm lub cev hlau. Qhov no yog physics. Lub ntsiab cai tseem ceeb ntawm kev tshem tawm xeb. Daim ntawv thov ntawm sab nraud quab yuam tuaj yeem nqa los ntawm sandblasting, tua blasting, sib tsoo, polishing, thiab lwm yam. Qhov sib xyaw ua ke ntawm cov hlau xeb feem ntau yog oxide lossis hydroxide ntawm cov hlau, yog li nws yooj yim rau cov tshuaj tiv thaiv nrog cov kua qaub.

Cov dej nag ntawm hydrogen tuaj yeem txo cov hlau oxide thiab sib nqus hlau oxide nyob rau hauv txheej txheej xeb ntawm cov tub rog kev lag luam mus rau ferrous oxide uas yooj yim kom hnov mob nrog cov kua qaub, uas muaj txiaj ntsig rau cov nplawm ntawm oxide, thiab nrawm nrawm ntawm qhov insoluble oxide nplai thiab ua kom nrawm oxidation. Kev tshem tawm cov teeb meem. Txawm li cas los xij, hydrogen kuj tseem tuaj yeem nqus tau los ntawm cov hlau puag los ua kom hydrogen embrittlement.
