▎ 摘　　要

NOVELTY - Chemical bath solution comprises 35-45g/L nickel acetate, 0.3-0.7g/L sodium borohydride, 40-50g/L ethylenediamine, 30-40g/L sodium hydroxide, 8-15g/L boric acid, 0.2-0.4g/L sodium dodecyl sulfate, 0.25-1g/L graphene oxide and balanced amount of distilled water. USE - Chemical bath solution used for coating surface of aluminum-silicon composite material (claimed). ADVANTAGE - The chemical bath solution enables to impart an improved oxidation resistance, corrosion resistance and good weldability properties to the coated surface of aluminum-silicon composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing chemical bath solution , which involves dissolving nickel acetate, sodium borohydride, ethylenediamine, sodium hydroxide, boric acid, sodium dodecyl sulfate and graphene oxide in balanced amount of distilled water, under continuous ultrasonic stirring condition to obtain the finished product.
