Abstract
จะทำให้เกิดชั้นเคลือบที่เกิดจากการแปลงเปลี่ยนเคมีของฟอตเฟตที่ทนต่อการสึกกร่อนบนผิวหน้าของวัสดุโลหะเหล็ก กล้าได้โดยใช้ขบวนการที่ประกอบด้วยการนำเอาวัสดุโลหะเหล็ก กล้าดังกล่าวมาสัมผัสกับของเหลวทำปฏิกิริยาที่ประกอบด้วย ผสมของแอนอิออนที่มี อิออนฟอสเฟต และอย่างน้อยที่สุดชนิด หนึ่งของแอคทีฟแอนอิออนชนิดอื่น , อิออนโลหะอย่างน้อยที่ สุดหนึ่งชนิด และสารออกซิไดซิงเพื่อให้เกิดชั้นเคลือบที เกิดจากการแปลงเปลี่ยนทางเคมีของฟอสเฟตบนผิวหน้าของวัสดุ โลหะเหล็กกล้าดังหล่าว ในที่ซึ่งอัตราส่วน (P/An) โดยน้ำ หนักของอิออนฟอสเฟต(P) ต่อแอนอิออนผสมทั้งหมด (An) เป็น 1/2 หรือน้อยกว่า และรักษาให้อุณหภูมิของของ เหลวทำปฏิกิริยาดังกล่าวอยู่ที่ระดับ 40 ซ. หรือน้อยกว่า โดยปราศจากการให้ความร้อนจากภายนอก Will form a coating resulting from chemical conversion of the corrosion-resistant phosphate on the surface of the ferrous metal material. Can be brave by using a process that consists of bringing iron metal materials Such plantain comes into contact with a reaction liquid that contains Mixtures of anionic anionic phosphate and at least the type One of the other active anion, at least one metal ion, and an oxidizing agent to form a coating that Caused by chemical conversion of phosphate on the surface of the material. Steel metal is so loud. Where the ratio (P / An) by ion phosphate weight (P) to total mixed anion (An) is 1/2 or less, and the temperature of The reaction liquid is 40C or less without external heating.
