HOT DIP Zn-Al-Mg-RE ALLOY PLATED FASTENER HAVING HIGH STRENGTH AND HIGH CORROSION RESISTANCE AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention is a high-strength and high-corrosion zinc-aluminum-magnesium for manufacturing fasteners with excellent corrosion resistance by plating fasteners of materials used for high-carbon industrial facilities, high-speed railways and bridges, such as SCM or S45C. -It relates to a method of manufacturing a rare earth alloy plating fastener, which is a pretreatment process (step S11), a heat treatment process (step S12), a plating treatment process (step S13), a coating layer control process (step S14), and a post-treatment process (step S15). ), and by establishing high-performance fastener manufacturing technology, it provides the effect of making a great contribution to the growth of the new and renewable energy market and securing national technological competitiveness by providing cost reduction, durability improvement, and maintenance cost reduction effects in the industry.
