Embodiment 1
[0022] Example 1: The preparation method of the anti-wear coating is as follows: immerse the stainless steel substrate in an acetone solution and sonicate for 1 hour; 98% concentrated sulfuric acid and 30% hydrogen peroxide solution are made into an oxidizing agent at a volume ratio of 3:1 to the substrate Carry out oxidation, wash and dry after reacting for 90 minutes; make a solution according to the ratio of aminosilane coupling agent (about 1% by volume fraction), acetone (about 80% by volume fraction), and water (about 19% by volume fraction), after fully stirring Immerse the stainless steel substrate in it and let it stand for 1h. Then soak it in 50ml of 0.4mg / ml graphene oxide solution. The solution casting process is kept at a temperature of 110°C. After the graphene oxide is coated on the stainless steel substrate, it is graphitized, that is, the sample is placed in a vacuum In a drying oven, treat at 100°C for 60 minutes.

[0023] Example 2: The preparation method of the anti-wear coating is as follows: immerse the stainless steel substrate in an acetone solution for 1 h; 98% concentrated sulfuric acid and 30% hydrogen peroxide solution are made into an oxidizing agent at a volume ratio of 2:1 to the substrate Carry out oxidation, wash and dry after reacting for 60 minutes; make a solution according to the ratio of aminosilane coupling agent (about 1% by volume fraction), acetone (about 80% by volume fraction), and water (about 19% by volume fraction), after fully stirring Immerse the stainless steel substrate in it and let it stand for 1h. Then soak it in 50ml of 0.6mg / ml graphene oxide solution. The solution casting process is kept at a temperature of 110°C. After the graphene oxide is coated on the stainless steel substrate, it is graphitized, that is, the sample is placed in a vacuum In a drying oven, treat at 120°C for 45min.
Embodiment 3
[0024] Example 3: The preparation method of the anti-wear coating is as follows: immerse the stainless steel substrate in an acetone solution for 1 h; 98% concentrated sulfuric acid and 30% hydrogen peroxide solution are made into an oxidizing agent at a volume ratio of 7:3 to the substrate Carry out oxidation, wash and dry after reacting for 30 minutes; make a solution according to the ratio of aminosilane coupling agent (about 1% by volume fraction), acetone (about 80% by volume fraction), and water (about 19% by volume fraction), after fully stirring Immerse the stainless steel substrate in it and let it stand for 1h. Then soak it in 50ml of 0.8mg / ml graphene oxide solution. The solution casting process is kept at a temperature of 110°C. After the graphene oxide is coated on the stainless steel substrate, it is graphitized, that is, the sample is placed in a vacuum In a drying oven, treat at 150°C for 30min.
