黄铜由于物理、机械性能优良和耐腐蚀性较好且价格低廉而被广泛应用于各产业部门。但黄铜在海水介质中易发生点蚀、晶间腐蚀和脱锌等局部腐蚀。几十年来人们把苯骈三氮唑(BTA)、巯基苯骈噻唑(MBT)作为防止铜及铜合金腐蚀的比较有效的缓蚀剂。
Brass is widely used in various industrial sectors due to its good physical and mechanical properties, good corrosion resistance and low cost. However, brass in the seawater medium prone to pitting, intergranular corrosion and dezincification and other local corrosion. For several decades, benzotriazole (BTA) and mercaptobenzothiazole (MBT) have been used as effective corrosion inhibitors to prevent the corrosion of copper and copper alloys.
