Abstract

The invention relates to an electroplated alloy, particularly to an electroplated zinc and copper alloy, which belongs to the metallurgy industry. The electroplated alloy comprises zinc cyanide, coprous cyanide, sodium cyanide, sodium citrate, potassium sodium tartrate and sodium hydroxide. The electroplated alloy is characterized in that D-potassium gluconate, ammonium nitrate, magnesium carbonate (anhydrous) and piperonal(dehyde) are added in the formula; the formula comprises the following components in parts by weight: 39 to 49 parts of zinc cyanide, 4 to 8 parts of coprous cyanide, 20 to 30 parts of sodium cyanide, 20 to 25 parts of sodium citrate, 25 to 35 parts of potassium sodium tartrate, 25 to 35 parts of sodium hydroxide, 40 to 50 parts of D-potassium gluconate, 0.5 to 1.5 parts of ammonium nitrate, 25 to 35 parts of magnesium carbonate (anhydrous) and 1 to 1.5 parts of piperonal(dehyde). The electroplated alloy is mainly used for daily products, such as glass frames, and the like. The electroplated zinc and copper alloy has the advantages of stable plated layer, strong corrosion resistance, long service life and low cost and is convenient in use.

Description

technical field [0001] The invention relates to an electroplated alloy, in particular to an electroplated zinc-copper alloy, which belongs to the metallurgical industry. Background technique [0002] With the rapid development of science and technology and modern industry, the requirements for the surface properties of materials are getting higher and higher. In surface treatment technology, electroplating is one of the most effective methods. In the past, it was mainly electroplating single metal, but it is far from meeting the high requirements for surface properties. Therefore, electroplating alloys have developed rapidly in the past 20 years. It can not only obtain surfaces with various special properties, but also has a wide variety and a wide range of options. Alloy plating refers to the process of co-depositing two or more metals using electrochemical methods. At present, more than 250 kinds of alloys have been studied at home and abroad, but there are only more th...
