▎ 摘 要
NOVELTY - Treating surface of stirring head, involves washing stirring needle three times with distilled water and drying. The surface is immersed in the composite brush plating solution for plating. The composite brush plating solution comprises a nickel cobalt plating solution, graphene, nano-titanium carbide and a composite powder. The composite powder comprises metal strontium powder, indium powder and vanadium powder. The thickness of plated layer is /(50 mu . USE - Method for treating surface of stirring head (claimed). ADVANTAGE - The method enables to treat surface of stirring head in a cost-effective manner by improving the hardness, abrasion resistance and service life of the needle.
