[0042] On the other hand, if figure 1 Shown, the present invention also provides a kind of preparation method of Ni-W-P-Zr multi-element micro-crystal coating, comprises the following steps: take by weighing each raw material of Ni-W-P-Zr multi-element micro-crystal plating solution, add water and stir to dissolve, adjust with pH adjuster The pH value of the solution is 4-10, and water is added to obtain a Ni-W-P-Zr multi-component microcrystalline plating solution; after pretreatment, the sample to be electroplated is immersed in the Ni-W-P-Zr multi-component microcrystalline plating solution for electroplating treatment , Obtain Ni-W-P-Zr multi-component microcrystalline coating.

[0043] In a specific embodiment, the pretreatment of the sample to be electroplated includes degreasing, rust removal, and pickling activation of the sample to be electroplated.

[0044] In a specific embodiment, the temperature during the electroplating treatment is 50-85°C, and the current dens...

Embodiment 1

[0047] A Ni-W-P-Zr multi-component microcrystalline coating is prepared by the following steps: weighing 15g / L of nickel sulfate, 40g / L of sodium tungstate, 150g / L of trisodium citrate, and 2g of α-zirconium hydrogen phosphate nanosheets / L, ammonium chloride 20g / L, sodium bromide 20g / L, cetyltrimethylammonium bromide 0.1g / L, saccharin 1g / L, add appropriate amount of water and heat and stir the reagent to dissolve, and prepare 1L solution (pH=7.5). Set the bath temperature at 75°C, use a graphite plate or titanium mesh as the anode (50 mm in length, 50 mm in width, and 2 cm in thickness), and use a pure iron sheet or carbon steel test piece as the cathode (50 mm in length, 50 mm in width, and 2 cm in thickness). at 5A / dm 2 The electroplating was carried out for 45 hours to obtain a Ni-W-P-Zr multi-component microcrystalline coating.

Embodiment 2

[0051] The difference from Example 1 is that this example prepares 4 kinds of Ni-W-P-Zr multi-component microcrystalline coatings with different contents of α-zirconium hydrogen phosphate nanosheets, the contents are 0.2g / L, 0.5g / L, 1g / L respectively , 5g / L.

Abstract

The invention discloses a Ni-W-P-Zr multi-element micro-crystal plating layer and plating solution and a preparation method thereof. The plating layer is composed of a nickel tungsten base plating layer and a zirconium phosphate nanometer enhancement phase. A zirconium phosphate nanometer sheet serves as a reinforcing material of the plating layer and a nucleation accelerator in the plating solution, by means of the electrostatic effect of the surface of the sheet, a hydration double-electrode layer is formed, surrounding ions are attracted, and deposited to the cathode surface under the effect of an electric field, and meanwhile, the deposition provides a nucleation site for electro-deposition of nickel tungsten. By means of introduction of the zirconium phosphate nanometer sheet, disorder deposition of a nickel tungsten alloy can be effectively restrained, the microstructure of the composite plating layer is optimized, thus self stress of the plating layer is offset, the toughness of the plating layer is improved, and finally, the crack-free Ni-W-P-Zr multi-element micro-crystal plating layer with the micro-crystal structure is obtained. The prepared crack-free Ni-W-P-Zr multi-element micro-crystal plating layer has good corrosion-resisting performance and abrasion-resisting performance.

Description

technical field [0001] The invention relates to the technical field of electrodeposition, in particular to a Ni-W-P-Zr multi-component microcrystalline coating, a coating solution and a preparation method thereof. Background technique [0002] In the field of oil and gas extraction and transportation, because the electrodeposited nickel-tungsten coating has good corrosion resistance and high hardness, it can meet the needs of oil and gas extraction, and has received widespread attention. However, due to the high hardness of nickel-tungsten alloy itself, defects such as microcracks and pinholes will occur in ordinary nickel-tungsten coatings. Moreover, in the environment of high salt, high sulfur content and carbon dioxide content in oil and gas extraction, microcracks and pinholes will cause the above-mentioned corrosive medium to directly react with the carbon steel below the coating. In addition, since the corrosion potential of iron is more negative than that of nickel, ...
