For this purpose, nine kinds of tubing materials were fitted in actual high pressure feedwater-heater of No.1 and No.2 units of Himeji No.1 Thermal Power Station, Kansai Electric Power Co., Inc. The results obtained are as follows: 1) Typical exfoliation type corrosion was formed on 70-30 cupro-nickel alloy. 2) 80-20, 90-10 cupro-nickel and 5% iron modified cupro-nickel did not form exfoliation type corrosion. 3) 70-30 nickel-copper alloy and the STC 52 A austenitic stainless steel formed a thin adherent oxide film and did not show measurable metal loss. 4) Three kinds of steel tubes were pitted in both drain and feedwater side, but not in the steam side. The pitting rates were about 0.3mm/yr. 5) From the above results, the material in actual units was replaced with 90-10 cupro-nickel tube to prevent exfoliation type corrosion.","PeriodicalId":441946,"journal":{"name":"CORROSION ENGINEERING DIGEST","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1966-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116980591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Critical potential for passivity and Flade potential shift towards noble direction with increasing chloride and hydrogen ion concentration, thus passivation becoming difficult. The critical potentials are expressed as E=E0+mlog[Cl-]-n(RT/ 0.4343F)pH, where R, the gas constant, T, absolute temperature, F, Faraday constant, E0 and m are constants. The constant n varies from 0.9 to 3.0 with environmental conditions such as temperature and kind of anion. Such different pH dependence of the critical potentials is attributed to the presence of different equilibrium surface reactions corresponding to passivation or activation for the respective corrosion conditions. The equilibrium reactions are considered to be Tia++2H2O=TiO2+4H++(4-a)e, 2Tib++3H2O=Ti2O3+6H++(6-2b)e, Ti+2H2O=TiO2+4H++4e, 2Ti+3H2O=Ti2O3+6H++6e. When the critical potentials expressed as equilibrium potentials of two former reactions, passivation or stability of passivity is affected directly by titanium ion. In such cases, as demonstrated for titanium-palladium alloy, corrosion resistance of titanium depends on the concentration of titanium ion in corrosive media.","PeriodicalId":441946,"journal":{"name":"CORROSION ENGINEERING DIGEST","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1965-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114744207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
