  • Corrosion-resistant sprayed coating, method for forming same and spraying device for forming same
    Patent number: 10323153
    Abstract: [Problem] To provide a corrosion-resistant coating that exhibits greater corrosion protection in saltwater environments and the like than was conventional, a method for forming the same, and a device for forming the same. [Solution] A corrosion-resistant alloy coating is formed on a substrate surface by: a) using a thermal spray gun, having a function wherein a flame including melted material particles is jetted toward a substrate, and the flame is partitioned from the open air in an upstream region on said jet path (which is to say the region in which the material particles are melted), and a function wherein, in a downstream region (the area continuing from the upstream region), the material particles and the flame are forcibly cooled by a jet-gas or jet-mist before reaching the substrate; and b) using a corrosion-resistant alloy material comprising aluminum, for the material particles.
