Nyob rau hauv metallurgy ntawm high - tensile hlau hlua, feem ntau insidious hem tsis yog sab nraud corrosion, tab sis sab hauv embrittlement. Hydrogen Embrittlement (HE) yog qhov tshwm sim uas atomic hydrogen diffuses rau hauv cov hlau lattice, cov ntsiab lus kev ntxhov siab hauv cheeb tsam, thiab pib tam sim ntawd, brittle tsis ua hauj lwm ntawm loads zoo hauv qab nominal breaking quab yuam.

Txoj kev nkag:

Hydrogen feem ntau nkag mus rau hauv cov hlau thaum "acid pickling" (kom tshem tawm cov nplai) lossis "electro-galvanizing." Thaum lub sij hawm cov txheej txheem tshuaj, nascent hydrogen atoms yog absorbed los ntawm cov hlau nto. Yog tias cov atoms no tsis "ci" los ntawm thermal nyem, lawv tsiv mus rau micro-voids thiab dislocations nyob rau hauv siab -carbon pearlite qauv. Nyob ntawd, lawv rov ua dua rau hauv molecular hydrogen, tsim kom muaj lub siab loj heev uas ua haujlwm zoo li lub ntsej muag microscopic.

Kev Tiv Thaiv Metallurgy ntawm SOLITE:

Txhawm rau tiv thaiv nws, SOLITE siv "Low-Hydrogen Protocol." Qhov no suav nrog kev tswj xyuas cov kua qaub nruj me ntsis thiab yuav tsum muaj hydrogen- nyem ci rau tag nrho cov khoom siv electro- plated. Rau ultra- siab- qib 2160 MPa ropes, peb siv tshwj xeeb inhibitors thaum lub sij hawm ntxuav. Nkag siab txog chemistry ntawm hydrogen atom yog qhov yuav tsum tau ua ua ntej rau engineering txoj hlua uas muaj kev nyab xeeb raws li nws muaj zog. Hauv kev lag luam hnyav, qhov koj tsis tuaj yeem pom -atomic-theem kev nkag siab- feem ntau yog qhov txiav txim siab qhov ua tiav ntawm koj lub nqa.
