## Description

- description: "This paper presents the effect of P addition on the corrosion resistance
    of steels before and after rust formation. Electrochemical measurements and surface
    analyses of P-containing steels (Fe-0.5 mass%P, Fe-1.0 mass%P, and Fe-1.5 mass%P)
    were conducted to analyze the contribution of P to their initial corrosion resistance
    before rust formation. The results showed that the initial corrosion resistance
    of the steel was worse with higher P content. According to the surface analysis
    conducted by SEM/EDS, more P-segregations at grain boundaries existed with higher
    P content. Based on the results of polarization measurements, it was considered
    that these P-segregation became the initiation sites of localized corrosion, resulting
    in the decrease in the initial corrosion resistance. \r\nAlthough the initial
    corrosion resistance was worse with higher P content, the long-term corrosion
    resistance was better with higher P content. According to the results of atmospheric
    exposure tests at Miyakojima and the surface analysis of rust layers, P was incorporated
    into the rust layer, and it promoted the protective ability against corrosion.\r\n"
