宁波地区当量加速环境谱的编制

首先利用宁波地区接近十年的环境资料数据编制了该地区的环境谱,其次基于电化学腐蚀原理和腐蚀电量相等的原理,建立了自然腐蚀环境向实验室加速环境折算的当量关系,并从力学性能和腐蚀深度进行验证,最后给出了可供实验室加速试验用的宁波地区加速环境谱。

Compiling of Environmental Spectrum of Equivalent Acceleration in Ningbo

Accelerated corrosion test in lab is necessary in order to study the reliability of iron tower in service. Environment spectrum of Ningbo province was compiled by using environmental data in 10 years. The equivalent relation between natural corrosion environment and lab acceleration environment was established based on principle of electrochemical corrosion and equivalent corrosion electricity, and was validated with mechanical properties and corrosion depth. The environmental spectrum for acceleration test of Ningbo was put forward.
