摘要:
Zn alloy particles for high corrosion resistance rust prevention paint containing, by mass %, Mg: 0.01 to 30% and having a balance of Zn and unavoidable impurities, having physical fracture facets and/or cracks of a length of 0.01 μm or more or cracks of a depth of 0.01 μm or more, having an average particle size of 0.05 to 200 μm, and having an aspect ratio of maximum size and minimum size (maximum size/minimum size) of an average value of 1 to 1.5. Also, a high corrosion resistance rust prevention paint containing these Zn alloy particles and a high corrosion resistance steel material and steel structure coated with that paint.
