基体上热喷镀金属镀层的方法是在1910年研制成的。这种方法在欧洲的应用比在美国更广泛。热喷镀层主要用于桥梁、塔和受到大气和潮汐区腐蚀作用的其它钢制设施的保护。但该镀层用于全浸于淡水和海水中的设施是有限的。 热喷镀所用的装置与油漆喷枪类似,而且几乎可用手工喷镀任何形状的零部件。热喷镀易自动化,尤其是管状构件可以将几个喷枪在管道旋转时沿其轴线移动。自动喷镀具有易控制镀层工序、镀层厚度均匀和降低成本的优点,保护钢件最常用的热喷镀材料是锌与铝。它们作为防蚀镀层和牺牲阳极镀层保护暴露在潮气中的钢基体。锌比较活泼,因而提供较好的阴
The method of thermal spraying metal plating on the substrate was developed in 1910. This method is more widely used in Europe than in the United States. The thermal spray coating is mainly used for the protection of bridges, towers and other steel facilities corroded by the atmosphere and the tidal zone. However, the use of this coating for immersion in freshwater and seawater is limited. The equipment used for thermal spraying is similar to a paint spray gun, and almost any shape of parts can be sprayed by hand. Thermal spraying is easy to automate, and in particular tubular members can move several lances along their axis as the pipe is rotated. Automatic spraying with easy to control the coating process, uniform coating thickness and reduce costs, the most commonly used thermal protection of steel spray material is zinc and aluminum. They protect the steel substrate exposed to moisture as an etch-resistant coating and a sacrificial anode coating. Zinc more lively, thus providing a better shade
