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.

Abstract: An adhesion preventive membrane including a nonwoven fabric layer of collagen fibers, having on a surface thereof a coating layer containing a mixture of collagen and hyaluronic acid, or a method of producing a continuous collagen single strand, wherein a strand-like collagen is dehydrated/coagulated in a hydrophilic organic solvent having a water content of about 10% or less and then dried under conditions of a relative humidity of about 50% or less and a temperature of about 42° C. or less. A collagen nonwoven fabric of first and second layers composed of a plurality of collagen strand-like materials spun out of a solubilized collagen solution, and arranged in parallel, the first and second layers being laminated and bonded to each other so that directions of arrangements of the strand-like materials of the first and the second layers are at an angle therebetween.
