An understanding of the interaction of calcareous deposits and biofoulants on the corrosion performance of steel during the fouling stage is both interesting and necessary. So, the effects of these factors on Q235 carbon steel were investigated and discussed for 20 weeks under real ocean conditions. The results indicate that calcareous deposits are favorable for the attachment of marine microorganisms. However, macroorganisms prefer adhering directly to the substrate. The generations of calcareous deposits have priority over the biofilm attachment under the condition of cathodic protection. Calcareous deposits can prevent steel against corrosion for four weeks without cathodic protection.
了解在污垢形成阶段钙质沉积物和生物污垢对钢的腐蚀性能的相互作用既有趣又必要。因此，在实际海洋条件下，对这些因素对Q235碳钢的影响进行了20周的研究和讨论。结果表明，钙质沉积物有利于海洋微生物的附着。然而，大型生物更喜欢直接附着在基体上。在阴极保护条件下，钙质沉积物的形成优先于生物膜的附着。在没有阴极保护的情况下，钙质沉积物可以防止钢腐蚀四周。
