In corrosion science, accurate determination of chloride ion deposition rates is critical to mitigating the environmental impact on structures. Traditional methods, such as the wet candle and dry plate methods (ISO 9225), are often inaccurate in capturing localized conditions and are also time-consuming and costly. The Bresle method, which measures soluble salts directly on metal surfaces, offers a more targeted approach. This article examines the Bresle method as an alternative for determining average monthly chloride ion deposition rates, including a regression analysis comparing the Bresle method with the wet candle method, and examines the long-term salinity of exposed surfaces in comparison with the additive approach to surface salinity. This paper hypothesizes that the Bresle method can be used as an alternative to the wet candle method. Linear regression analysis shows a strong correlation in chloride ion deposition rates compared to those measured by the wet candle method. However, cumulative measurements using long-term exposed coupons are unreliable due to inconsistent trends.
在腐蚀科学中,准确测定氯离子沉积速率对于减轻环境对结构的影响至关重要。传统方法,如湿烛法和干板法(ISO 9225),在捕捉局部条件时往往不准确,而且耗时且成本高。直接在金属表面测量可溶性盐的布雷斯勒法提供了一种更具针对性的方法。本文研究了布雷斯勒法作为确定月平均氯离子沉积速率的替代方法,包括将布雷斯勒法与湿烛法进行比较的回归分析,并与表面盐度的累加方法相比,研究了暴露表面的长期盐度。本文假设布雷斯勒法可作为湿烛法的替代方法。线性回归分析表明,与湿烛法测量的氯离子沉积速率相比,两者具有很强的相关性。然而,由于趋势不一致,使用长期暴露试样的累积测量结果并不可靠。
