▎ 摘 要
NOVELTY - The method involves slowly pouring 50g of graphene nanosheets into a mixed acid with concentrated sulfuric acid and concentrated nitric acid. A mixed solution of tin chloride and hydrochloric acid as the sensitization solution is provided. The oxidized graphene nanosheets are slowly poured into the sensitization solution while magnetically stirring them. The palladium chloride solution and hydrochloric acid are mixed as the activation solution. The liquid A is poured into liquid B and the activated graphene powder is added, and magnetic stirring is used to make it evenly mixed. The pH of the plating solution to 10-12 with a 20 percentage of sodium hydroxide aqueous solution is adjusted. 5 ml of hydrazine hydrate is added as a reducing agent to the mixed solution. The powder with the composition ratio of nickel and cobalt with specified percentage of the total component content of titanium carbon powder into three portions. The three portions of the mixed powder is separated in order. USE - Method for ultrasonic-assisted three dimensional (3D) printing of turbocharged blades and nano-gradient coatings. ADVANTAGE - The method is configured to significantly improve the thermal shock resistance and service life of the thermal barrier coating, effectively solve the problem of coating cracks and shedding caused by repeated thermal shocks at high and low temperatures. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of the cemented carbide tool. Turbocharger sheet substrate (1) TGO adhesive layer (2) Titanium carbon accounting for five percentage of the total mass (3) Titanium carbon accounting for ten percentage of the total mass (4) Titanium carbon accounting for fifteen percentage of total mass (5)
