Research on Anti-Erosion Mechanical Properties of Steel Structure Coating

Abstract:

Steel structures are seriously affected by sandstorm in the central and western regions of Inner Mongolia, this influence is mainly reflected erosion damage to the steel structure coating by sandstorm. As the coating has critical protection role to the durability of steel structure, the damage of coating will directly lead to reduce durability and safety of steel structure system. This paper researches on the anti-erosion mechanical properties of steel structure coating materials, and measures hardness, modulus , thickness and density of the coating by use of micron-indenter and traditional methods, the result shows that hardness is 2.1516MPa, modulus is 15.62MPa, thickness distribution is in the 800um ~ 1000um and density is 1.71g/cm³. This research result will provide the basis for preparation of anti-erosion coating and evaluation safety and durability of steel structures.
