Embodiment 1
[0032] In this embodiment, the base material is a 316L stainless steel sheet with a thickness of about 2mm, TiO 2 The thickness of the coating is 40 μm, and the TiO 2The crystal phase composition is anatase phase and rutile phase. According to the mass fraction, the anatase type accounts for 80%. The surface of the coating is a porous nanostructure. The aluminum coating is used as a transition layer between the substrate and the nanostructure coating. , with a thickness of 250 μm. The concrete preparation method of this coating is as follows:
[0033] 1. Mix deionized water and absolute ethanol at a volume ratio of 4:1 to make a solution, and commercially available TiO with an average particle size of 20nm 2 The nano-powder is added to the above prepared solution at a ratio of 3wt%, and the magnetic stirring is mixed evenly, and the aqueous polyurethane solution (PU) and polyvinylpyrrolidone (PVP) are respectively added to the above-mentioned preparation at a ratio of 0.7wt%...
