Acid embrittlement yog dab tsi (los yog hydrogen embrittlement), thiab nws tshwm sim li cas?

Lub thiaj li hu ua acid embrittlement ntawm steel kav yog hais txog qhov tshwm sim uas lub zog txhua yam ntawm cov kav hlau txo qis thiab cov hlau ua nkig tom qab pickling. Qhov tsis xws ntawm acid embrittlement nyob rau hauv cov kav hlau yog tshwm sim los ntawm kev tsim cov hydrogen atoms thaum lub sij hawm pickling txheej txheem. Ib co ntawm cov hydrogen atoms diffuse mus rau hauv -iron lattice qhov chaw nyob rau hauv lub steel yeeb nkab matrix. Vim lawv qhov ntim nthuav dav, kev ntxhov siab yog tsim nyob rau hauv cov yeeb nkab steel matrix, uas ua rau lub zog sib txuas hauv matrix tsis muaj zog, ua rau cov yeeb nkab steel matrix ua nkig thiab tom qab ntawd txo nws cov khoom siv zog.
