抗腐蚀热喷涂技术广泛地运用于防止钢在海洋环境中由于腐蚀和气蚀受到损害。为了改善用于船舶材料的低温热喷涂85%Al-14.5%Zn-0.5%Zr涂层合金的耐久性,对其采用了多种密封材料,并考察其电化学行为和空蚀特征。结果表明:密封材料能改善涂层材料的性能。其中,混合陶瓷和氟-硅密封材料有着良好的电化学性能,并且氟-硅密封材料具有最佳的抗空蚀性能。 Corrosion-resistant thermal spray technology is widely used to prevent steel from being damaged by corrosion and cavitation in the marine environment. In order to improve the durability of low temperature thermal sprayed 85% Al-14.5% Zn-0.5% Zr coated alloy for marine materials, a variety of sealing materials were used and the electrochemical behavior and cavitation characteristics were investigated. The results show that the sealing material can improve the properties of the coating material. Among them, the hybrid ceramic and fluorine-silicon seal material has good electrochemical properties, and fluorine-silicon seal material has the best cavitation erosion resistance.
