Example Embodiment

[0017] The plating solution used in this embodiment includes NiSO 4 ·6H 2 O: 20g / L, NaH 2 PO 2 ·H 2 O: 20g / L, C 6 H 8 O 7 ·H 2 O: 5g / L, CH 3 CHOHCOOH 10g / L, NH 4 HF 2 : 15g / L, HF (40%): 10ml / L, NCSNH 2 0.6mg / L, NH 4 OH 50ml / L, C 6 H 5 NaO 7 ·2H 2 O: 15 g / L.

[0018] The preparation method of the plating solution used in this method is the same as the conventional plating solution preparation method. The preparation of the chemical plating solution: first dissolve the above-mentioned drugs with distilled water, dilute to the corresponding concentration and mix, and then adjust the pH value to 6.0, the obtained solution That is, chemical plating solution.

[0019] Before electroless nickel plating of magnesium alloy specimens, pre-plating treatment should be performed on magnesium alloy specimens. The treatment process includes: grinding, cleaning, alkali cleaning, pickling and activation. After each step, it needs to be washed with distilled water and then d...

Abstract

The invention discloses a chemical nickel-plating solution. The chemical nickel-plating solution comprises the following components: 10-30g/L of NiSO4.6H2O, 10-30g/L of NaH2PO2.H2O, 3-8g/L of C6H8O7.H2O, 5-20g/L of CH3CHOHCOOH, 8-25g/L of NH4HF2, 5-20ml/L of 20-50% HF, 0.2-1mg/L of NCSNH2, 20-80ml/L of NH4OH and 10-30g/L of C6H5NaO7.2H2O. According to the invention, the nickel layer with low porosity can be obtained by carrying out chemical nickel plating utilizing the chemical nickel-plating solution. The preparation method is simple in process, and is easy to control; and the chemical nickel-plating solution has a good film forming effect, and can be used for solving the problem that the anticorrosion property of the chemical nickel-plating layer is low.

Description

technical field [0001] The invention relates to electroless nickel plating, a surface treatment method of magnesium alloy, specifically a preparation method of magnesium alloy electroless nickel plating solution and low porosity electroless nickel plating layer. Background technique [0002] Due to its small specific gravity, high strength, good thermal conductivity, good shock absorption and easy recycling, magnesium alloy is called the green engineering material of the 21st century and is widely used in aviation, aerospace, automobile industry and 3C products . However, the poor corrosion resistance of magnesium alloys restricts its application. [0003] At present, there are many surface treatment methods widely used to improve the corrosion resistance of magnesium alloys, but the electroless nickel plating method is generally used to protect magnesium alloys. For example, CN1598053A discloses a process for carrying out electroless nickel plating on magnesium alloys. In...
