Acid Embrittlement (los yog Hydrogen Embrittlement)

Lub sij hawm "acid embrittlement" ntawm cov kav hlau yog hais txog kev txo qis hauv cov khoom siv dag zog thiab embrittlement ntawm steel zoo tom qab pickling. Qhov tshwm sim ntawm acid embrittlement defects nyob rau hauv steel kav yog vim lub tiam ntawm 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 sab hauv ntawm lub matrix tsis muaj zog, ua rau lub matrix, thiab yog li txo cov neeg kho tshuab lub zog ntawm cov kav hlau steel.
