水利工程构造物，需要使用大量的钢结构，处于高速水流、机械碰撞、摩察或露在大气中，接触酸、碱、盐和各种水质等腐蚀介质中，不同程度地受自然的、物理的化学的腐蚀破坏，造成了工程管理困难和水利经济的损失。地处东北高寒地区的引嫩工程，１９８０年首先在１０００ｍ￣２的钢闸门防蚀工作中使用了金属锌气喷涂技术措施，经过１５年的使用观测，和经省内专家鉴定，效果很好。
Hydraulic structures need to use a large number of steel structures in high-speed water, mechanical collision, Mocha or exposed to the atmosphere, contact with acid, alkali, salt and various water quality and other corrosive media, to varying degrees, by the natural, physical Chemical corrosion damage, resulting in engineering management difficulties and water conservancy economy. Located in the northeast alpine region tender project, in 1980 first in 1000m ~ 2 steel gate anti-corrosion work using metal zinc gas spraying technology measures, after 15 years of observation, and the identification of experts in the province, the effect is very good .
