Problems solved by technology

[0011] Electrodeposited Fe-Zn alloy can be obtained through this electrodeposition solution formula, but the obtained alloy coating has high oxygen content, large internal stress, poor plastic toughness, severe cracking, and complete bulk materials cannot be obtained. The ratio of the solute also cannot obtain an alloy coating with better performance, so that the Fe-Zn alloy cannot be practically applied

Abstract

The invention discloses an electrodeposition Fe-Zn alloy plating solution, and belongs to the technical field of material surfaces. The pH value of the Fe-Zn alloy plating solution is 2-3, the Fe-Zn alloy plating solution comprises a solvent and a solvent, wherein the solvent is deionized water; the solute comprises the following components of, in percentage by weight, main salt FeCl2.4H2O, auxiliary main salt ZnCl2, conductive salt NaCl, antioxidant MnCl2.4H2O for refining crystal grains and reducing agent ascorbic acid, complexing agent sodium citrate, wetting agent sodium dodecyl sulfate and pliable agent saccharin sodium, and the solute further comprises malonic acid with the concentration of 5-16 g / L is used as an antioxidant, and boric acid with the concentration is 30-50 g / L is usedfor controlling the content of the cathode OH<->. According to the electrodeposition Fe-Zn alloy plating solution, malonic acid and boric acid are added as antioxidants, so that Fe<2+> can be inhibited from being oxidized into Fe<3+>, the local pH of the cathode is effectively controlled to be excessively high, and therefore the problem that the oxygen content of the coating is high, the internalstress is large, the cracking problem is easily caused are effectively solved, the internal stress of the coating is reduced, and the toughness is further improved.

Description

technical field [0001] The invention belongs to the technical field of material surfaces, and relates to an electrodeposited Fe-Zn alloy plating solution. Background technique [0002] At present, researchers of biodegradable scaffold materials have begun to turn their attention to degradable metal materials. Magnesium, iron, zinc and their respective alloys have gradually become a hotspot in the research of degradable scaffold materials due to their excellent mechanical properties, biocompatibility, and easy corrosion characteristics. Iron and zinc have their own advantages, so that Fe-Zn alloy scaffold materials are paid more and more attention. However, due to the high melting point difference between Fe and Zn, it is difficult to dissolve each other at low temperature, and it is difficult to obtain the alloy of the two by traditional metallurgical methods. Therefore, The Fe-Zn alloy is obtained by electrodeposition, and the plating solution formula used is: [0003] Fe...
