Abstract
แผ่นเหล็กกล้าเคลือบจำพวก Al-Zn ซึ่งควบคุมการเกิดการบวมของฟิล์มเคลือบ และมี ความทนต่อการกัดกร่อนหลังการเคลือบสีที่ดีเยี่ยม แผ่นเหล็กกล้าเคลือบจำพวก Al-Zn ซึ่งมีชั้นเคลือบจำพวก Al-Zn ซึ่งประกอบด้วย 2 ชั้น ของชั้นโลหะผสมบริเวณพื้นผิวซึ่งมีอยู่ที่บริเวณพื้นผิวระหว่างกับแผ่นกล้ารองพื้น และชั้นบน นั้น อยู่ที่พื้นผิวแผ่นเหล็กกล้า ชั้นบนมีองค์ประกอบของสารประกอบระหว่าง Si และ Ca หรือ ประกอบเพิ่มเติมด้วย Al, รวมทั้งสัดส่วน mass% ของ Ca/Si ของชั้นบนดังกล่าวคือ 0.72-1.4 ชั้นโลหะผสมบริเวณพื้นผิวเกิดจากสารประกอบจำพวก Fe-Al และ/หรือ จำพวก Fe-Al-Si มี ปริมาณองค์ประกอบของ Si ของชั้นบน 0.1-2.0 mass% ปริมาณองค์ประกอบของ Ca 0.001 - 2.0 mass% Al-Zn coated steel plates which control film swelling and have excellent corrosion resistance after painting. Al-Zn coated steel plate with Al-Zn coating consists of two layers of alloy layer on the substrate, which is present on the surface between the substrate and the top layer on the surface of the sheet. The upper layer contains compounds between Si and Ca, or additionally Al, as well as the mass% Ca / Si proportion of the above layers is 0.72-1.4. The surface alloy layer is formed by compounds like Fe-Al and / or. Fe-Al-Si was the composition of Si of the upper layer 0.1-2.0 mass%, the composition of Ca 0.001 - 2.0 mass%.
