The effect of deep‐sea environments on the properties of calcareous deposits was studied and we established the mapping relationship between their cathodic protection potential and the temperature (T), pressure (P), dissolved oxygen (DO), and the properties of the calcareous deposits according to the response surface methodology. This revealed that the calcareous deposits mixed with CaCO₃ and Mg(OH)₂ under cathodic protection. The environment including temperature, pressure, and oxygen content had various impacts on the thickness, porosity, and the ratio of Ca and Mg. Moreover, the calcareous deposits slightly decreased the cathodic protection potential. Therefore, it can be believed that the cathodic protection potential for naked high‐strength steel is also approximately applicable to that covered with calcareous deposits in the deep‐sea environment.

响应面法研究钙质沉积物对深海环境中10Ni5CrMoV高强度钢阴极保护电位的影响

研究了深海环境对钙质矿床性质的影响，并建立了其阴极保护电位与温度（T），压力（P），溶解氧（DO）和钙质性质之间的映射关系。根据响应面方法进行沉积。这表明钙质沉积物与CaCO ₃和Mg（OH）_2混合在阴极保护下。温度，压力和氧含量等环境对厚度，孔隙率以及Ca和Mg的比例有各种影响。此外，钙质沉积物略微降低了阴极保护的潜力。因此，可以认为裸露的高强度钢的阴极保护潜力也近似适用于深海环境中覆盖有钙质沉积物的阴极保护潜力。
