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。
Zinc and zinc-aluminum thermal spray coatings provide maximum corrosion protection for steel bars in steel structures and concrete. Zinc and zinc-aluminum alloy thermal spray coating main processing methods arc spraying and flame spraying, can form a sealing layer on the surface of the substrate, which resulted in an optimal combination of passive and active corrosion protection system, making the use of the workpiece Life expectancy up to 20 years. In this paper, the microscopic properties of zinc and zinc-aluminum thermal sprayed coatings and the corrosion protection characteristics near the actual working conditions were studied.
