Cov neeg uas siv cov co muaj hlau paub tias hydrogen hnyuv yog ib qho ua rau muaj kev raug mob rau cov txiv ntseej. Piv txwv, nws yooj yim ua rau kev txhav tawg. Yog tias nws tsis tau paub ua ntej, nws yuav ua rau muaj kev raug mob loj. Yog li ntawd, cov kua txiv hmab txiv ntoo ntawm lub txiv ntoo yog muab tshem tawm thiab tshem tawm. Kev sib xyaw cov txheej txheem ntawm cov kua txiv hmab txiv ntoo yog qhov kev ziab kom qhuav. Yuav ua li cas yuav tsum tau muab sau cia thaum lub sij hawm ziab ntawm cov txiv ntoo?
1, yuav tsum tsis txhob siv los npau qhov kub ntawm qhov chaw;
2. Kev ziab kom qhuav yuav tsum tau ua tom qab electroplating (dua li ntawm 1 h), tam sim ntawd ua ntej chromate passivation;
3, ziab kub yog 200-230 ° C yog qhov tsim nyog, feem ntau qis ziab thiab ntev ziab qhuav;
4, qhov ntev qhuav yog xaiv nyob rau hauv 2-24h, feem ntau 8h ziab ntev.
