| 摘 要： | 锌及锌铝合金热喷涂涂层可以最大限度地为钢结构件和混凝土中的钢筋提供腐蚀防护。锌及锌铝合金热喷涂涂层主要的加工方式为电弧喷涂和火焰喷涂，可以在基体表面形成密封层，这就产生了一个最佳的被动与主动相结合的腐蚀防护体系，使得工件的使用寿命延长到20年。本文研究了锌及锌铝合金热喷涂涂层的微观属性和接近实际工况时的腐蚀防护特点。

| Abstract: | Thermally sprayed coatings of zinc, and in particular zincaluminium alloys,offer maximum corrosion protection for steel structures and reinforcing steel in concrete. They are primarily produced by arc or flame spraying. The surfaces of zinc and zinc alloy spray coatings can be protected by sealing top coats. This produces an optimum combination of passive and active corrosion protection and allows a service life of over 20 years.The development of new materials assumes intensive investigations. This paper provides an overview of the properties of thermally sprayed zinc and zinc-aluminium alloys as well as their microstructure and investigates the corrosion protection effect in tests and near-practical conditions. |
