Nthuav cov lus qhia

Lub zog zog ceev yuav tsim cov nkig thaum galvanized. Xav tau kev saib xyuas tshwj xeeb.

Hydrogen embrittlement feem ntau yog tus cwj pwm los ntawm kev qeeb qeeb qeeb hauv kev ntxhov siab. Muaj cov springs tsheb, ntxhua khaub ncaws, screws, sheet springs thiab lwm yam galvanized ntu, hauv ob peb teev tau tawg, qhov kev sib dhos ua ntu zus ntawm 40% ~ 50%. Nyob rau hauv cov txheej txheem ntawm kev siv cadmium-plated seem ntawm cov khoom tshwj xeeb, thiab cov teeb meem tseem ceeb yog daws tau cov txheej txheem dhydrogen ua nruj. Tsis tas li ntawd, muaj qee cov hydrogen embrittlement tsis qhia qeeb banger- xws li muaj hlau hluav taws xob (hydrogen loj dua, feem ntau tshwm sim hauv kev siv cov quav tshwm sim brittle bacture tshwm sim; Lub Mandrel ntawm rab phom, tom qab ob peb zaug ntawm Chroming, poob rau hauv av thiab tawg; Qee qhov kev txiav txim siab (sab hauv kev ntxhov siab loj) yuav tawg thaum pickling. Cov ntu no yog cov hydrogenated loj heev thiab tawg tsis muaj kev ntxhov siab sab nraud, uas tsis tuaj yeem siv dua qub los ntawm kev ua haujlwm ruaj khov los ntawm dehydrogenation.

Qhov siab dua cov khoom siv zog, ntau dua cov hydrogen embrittordity. Nov yog cov ntsiab lus tseem ceeb uas yuav tsum tau hais meej los ntawm cov kws tshaj lij kev kho mob hauv cov txheej txheem hluav taws xob. Cov hlau nrog tensile zog σB> 105kg / mm2 yuav tsum tau los ntawm cov qauv kev nyuaj siab thoob ntiaj teb yuav tsum raug ua ntej plating kev kho kom haum raws li kev kho mob. Fabkis Aviation yuav tsum muaj kev kho kom zoo rau cov hlau seem rau cov khoom siv hluav taws xob nrog cov txiaj ntsig σs> 90kg / mm2.

Vim yog qhov zoo sib tham ntawm cov hlau muaj zog thiab hardness, nws yog qhov yooj yim los txiav txim siab rau cov khoom siv hydrogenlement ntawm cov khoom siv los ntawm lub zog. Vim tias cov khoom lag luam zoo nkauj thiab cov khoom siv tau cim yuav tsum khij nrog cov tawv tawv. Nyob rau hauv lub electroplating, peb pom tias lub hardness ntawm steel nyob ib ncig ntawm HRC38 pib qhia qhov kev pheej hmoo ntawm hydrogen embritting. Rau qhov chaw siab dua HRC43, dehydogenation yuav tsum raug txiav txim siab tom qab plating. Thaum lub hardness yog hais txog HRC60, dehydrogenation kev kho mob yuav tsum tau nqa tawm sai li tom qab kev kho mob, txwv tsis pub cov hlau ntu yuav tawg hauv ob peb teev.
