Embodiment 1

[0032] Plating solution composition:

[0033]

[0034] The balance is water

[0035] Electroplating method: use a thin-walled iron pipe with an inner diameter of Ф10X100mm, and conduct an electroplating test in a 1000ml beaker. The conditions are: temperature 50°C, DC current 1 ampere, electroplating for 8 minutes, nickel plate for the anode, and nickel-plated iron pipe A1.

[0036] Evaluation of electroplating effect: Observe the length of the nickel layer plated on the inner wall of the iron pipe to be 100mm, and then evaluate the covering ability of the plating solution. The nickel-plated iron pipe A1 was subjected to a neutral salt spray test for 8 hours, and no corrosion of the nickel layer was found.

Embodiment 2

[0038] Plating solution composition:

[0039]

[0040] The balance is water

[0041] Electroplating method: use a thin-walled iron pipe with an inner diameter of Ф10X100mm, and conduct an electroplating test in a 1000ml beaker. The conditions are: temperature 55°C, DC current 0.5 ampere, electroplating for 7 minutes, and anode using a nickel plate to obtain a nickel-plated iron pipe A2.

[0042] Evaluation of electroplating effect: Observe the length of the nickel layer plated on the inner wall of the iron pipe to be 100mm, and then evaluate the covering ability of the plating solution. The nickel-plated iron pipe A2 was subjected to a neutral salt spray test for 7 hours, and no corrosion of the nickel layer was found.

Embodiment 3

[0044] Plating solution composition:

[0045]

[0046] The balance is water

[0047] Electroplating method: use a thin-walled iron pipe with an inner diameter of Ф10X100mm, and conduct an electroplating test in a 1000ml beaker. The conditions are: temperature 55°C, DC current 0.5 ampere, electroplating for 7 minutes, and anode using a nickel plate to obtain a nickel-plated iron pipe A3.

[0048] Evaluation of electroplating effect: Observe the length of the nickel layer plated on the inner wall of the iron pipe to be 100mm, and then evaluate the covering ability of the plating solution. The nickel-plated iron pipe A3 was subjected to a neutral salt spray test for 7 hours, and no corrosion of the nickel layer was found.

Abstract

The invention provides nickel electroplating solution and an electroplating method thereof. The nickel electroplating solution comprises main salt, stabilizer, complexing agent, conducting salt and reducing agent, wherein the content of the reducing agent is 10-40g / liter. The electroplating method adopting the nickel electroplating solution comprises the following steps of: firstly, putting the metal nickel into nickel electroplating solution to serve as an anode; putting a workpiece into the nickel electroplating solution to serve as a cathode; and finally, introducing a direct-current power supply, wherein the cathode current density is 0.5-5 amperes / square centimtre, the electroplating solution temperature is 40-55DEG C, and the electroplating time is 1-10 minutes. According to the invention, the technical problems existing in the traditional electronickelling and chemical nickel-plating are solved. Reducing agent is added into the electroplating solution to obviously improve the plating solution coverage capability and the corrosion-resistant capability of a nickel layer, and the electroplating solution has the advantages of strong corrosion-resistant capability and good coverage capability.

Description

technical field [0001] The invention relates to the field of metal material electroplating, in particular to a nickel electroplating solution and an electroplating method thereof. Background technique [0002] Nickel has excellent decorative and functional properties, and is currently one of the most commonly used plating types. The process is divided into two different types of electroplating nickel and chemical nickel. The advantages of electroplating nickel are fine crystallization of the coating, smooth and bright, less internal stress, and strong bonding with the substrate. The disadvantages of electroplating nickel are: ① It is greatly affected by the cleanliness of the substrate surface and the purity of the plating solution, resulting in many defects in the substrate after electroplating, such as peeling, blistering, pitting, black spots, etc.; The impact of different positions in the plating tank and the tool will result in poor throwing ability. In addition, the ...
