▎ 摘　　要

NOVELTY - Preparing in-situ synthesis enhanced additive composite powder comprises (i) synchronously and slowly adding the titanium source precursor and dropping the hydrolysis inhibitor to deionized water, adjusting the pH of the system to 2.5-3.5 using an acid solution to under continuous stirring conditions, and continuing the hydrolysis reaction to form a titanium dioxide sol, (ii) adding the single-layer graphene powder into the titanium dioxide sol and dispersing uniformly, coating titanium dioxide sol on the surface of the single-layer graphene powder, aging, drying, grinding and sieving at room temperature to obtain TiO2-graphite alkene sol-coated powder, and (iii) ball-milling the TiO2-graphene sol-coated powder and the aluminum alloy powder and mixing. USE - Preparation of in-situ synthesis enhanced additive composite powder used in national defense and military industry, aerospace industry, automobile manufacturing and energy power. ADVANTAGE - The in-situ synthesis enhanced additive composite powder has improved laser energy utilization rate of the aluminum alloy powder, and improves the comprehensive performance of the composite material, and is clean without pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an in-situ synthesis enhanced additive composite powder. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of preparing in-situ synthesis enhanced additive composite powder (Drawing includes non-English language text).
