a.number of studies ha.e been reported on the use of na.ocrysta.line pla.ma.electrolytic nitroca.burising technology for surfa.e ha.dening of sta.nless steels for higher corrosion resista.ce resulted from this technique. However, very few studies ha.e focused on the optimiza.ion of the na.ocrysta.line pla.ma.electrolytic nitroca.burising process pa.a.eters. In this study, a.design of experiment （DOE） technique, the Ta.uchi method, ha. been used to optimize the na.ocrysta.line pla.ma.electrolytic nitroca.burising not only for surfa.e ha.dening but a.so for the corrosion protection of 316L a.stenitic sta.nless steel by controlling the coa.ing processes fa.tors. The experimenta. design consisted of four fa.tors （Urea.concentra.ion, electrica. conductivity of electrolyte, volta.e a.d dura.ion of process）, ea.h conta.ning three levels. Potentiodyna.ic pola.iza.ion mea.urements were ca.ried out to determine the corrosion resista.ce of the coa.ed sa.ples. The results were a.a.yzed with rela.ed softwa.e. a. a.a.ysis of the mea. of signa.-to-noise （S/N） ra.io indica.ed tha. the corrosion resista.ce of na.ocrysta.line pla.ma.electrolytic nitroca.burised 316L sta.nless steel wa. influenced significa.tly by the levels in the Ta.uchi orthogona. a.ra.. The optimized coa.ing pa.a.eters for corrosion resista.ce a.e 1150 g/L for urea.concentra.ion, 360 mS/cm for electrica. conductivity of electrolyte, 260 V for a.plied volta.e, 6 min for trea.ment time. The percenta.e of contribution for ea.h fa.tor wa. determined by the a.a.ysis of va.ia.ce （a.OVa.. The results showed tha. the a.plied volta.e is the most significa.t fa.tor a.fecting the corrosion resista.ce of the coa.ings.

Numerica. a.proa.h for a.mospheric Corrosion Monitoring Ba.ed on EIS of a.Wea.hering Steel

引用

a.ta.Meta.lurgica.Sinica.English Letters) 2015年第2期28卷 261-271页

作者： ch.Thee Long Ha. Jun-Hua.Dong Xin Mu Wei Ke Sta.e Key La.ora.ory for Corrosion a.d Protection Institute of Metal Research Chinese Academy of Sciences

Electrochemica. impeda.ce spectroscopy （EIS） a.d film thickness mea.urement ha.e been employed to study the a.mospheric corrosion of a.wea.hering steel covered with a.thin electrolyte la.er in a.simula.ed coa.ta.-industria. a.mosphere. The results indica.e tha. the corrosion ra.e is a.function of the covered electrolyte thickness a.d the wet/dry cycle. Within ea.h wet/dry cycle, the increa.ed corrosion ra.e is rela.ed to the increa.ed Cl^- a.d SO4^2- concentra.ion a.d a. enha.cement of oxygen diffusion ra.e with the eva.ora.ion of the electrolyte. In a.dition, the corrosion ra.e increa.es during the initia. corrosion sta.e a.d then decrea.es a. the wet/dry cycle proceeds. Moreover, one ma.hema.ica. a.proa.h ba.ed on the numerica. integra.ion method to obta.n corrosion ma.s loss of steel from the mea.urements of EIS ha. been developed, a.d this would be useful for the development of indoor simula.ed a.mospheric corrosion tests.
