Embodiment 1
[0037] This embodiment provides a surface treatment method for an aluminum alloy engine cylinder head, comprising the following steps:
[0038] (1) Electrolysis process: Electrolyze the cylinder head in the electrolyte solution set in the electrolytic cell;
[0039] In the electrolyte, the concentration of sodium sulfate is 15g / L, the concentration of zinc oxide is 3g / L, the concentration of sodium peroxide is 3g / L, the concentration of sodium dodecylsulfonate is 2g / L, and the balance is water; The density is 1A / dm 2 , The electrolysis time is 5 minutes.
[0040] (2) Soaking process: put the electrolyzed cylinder head into the protective solution for 30 seconds;
[0041] (3) Curing process: After the cylinder head is pulled out, use a high-pressure air gun to blow off the excess sol gel hanging on the surface of the cylinder head, and dry the cylinder head naturally to cure, so that the surface of the cylinder head can prevent aluminum alloy from forming. Discoloration, mil...
Embodiment 2
[0043] This embodiment provides a surface treatment method for an aluminum alloy engine cylinder head, comprising the following steps:
[0044] (1) Electrolysis process: Electrolyze the cylinder head in the electrolyte solution set in the electrolytic cell;
[0045] In the electrolyte, the concentration of sodium sulfate is 18g / L, the concentration of zinc oxide is 3.5g / L, the concentration of sodium peroxide is 4g / L, the concentration of sodium dodecylsulfonate is 1g / L, and the balance is water; The density is 2A / dm 2 , The electrolysis time is 4 minutes.
[0046] (2) Soaking process: put the electrolyzed cylinder head into the protective solution for 30 seconds;
[0047] (3) Curing process: After the cylinder head is pulled out, use a high-pressure air gun to blow off the excess sol gel hanging on the surface of the cylinder head, and dry the cylinder head naturally to cure, so that the surface of the cylinder head can prevent aluminum alloy from forming.
