On the basis of their potential passivating characteristics, in this study, borates have been used to synthesize a novel slow-release inhibitor to suppress long-term mild steel corrosion in simulated recirculating water. The passivating performance was characterized by various electrochemical measurements and the passivating mechanism was interpreted by the point defect model. The experimental results indicated that the slow-release inhibitor exhibited a passivating efficiency of over 98% after 30 days of immersion, due to the formation of a passive film that was predominant by a Fe–O–B structure on the mild steel surface. This study provides a novel controlled-release concept and a slow-release borate inhibitor to control long-term corrosion.

迈向缓释硼酸盐抑制剂以控制模拟循环水中的轻度钢腐蚀

基于其潜在的钝化特性，在这项研究中，硼酸盐已用于合成新型缓释抑制剂，以抑制模拟循环水中长期低碳钢的腐蚀。通过各种电化学测量表征钝化性能，并通过点缺陷模型解释钝化机理。实验结果表明，缓释抑制剂在浸泡30天后表现出超过98％的钝化效率，这是由于在低碳钢表面上形成了以Fe–O–B结构为主的钝化膜。这项研究提供了新颖的控释概念和缓释硼酸盐抑制剂来控制长期腐蚀。
