▎ 摘  要

NOVELTY - A crack recovery in products comprises preparing aqueous solution or organic solution containing graphene; immersing parts having defects in the graphene-containing solution to make the graphene permeate in the crack; and taking out the product, drying, and sintering at high temperature. USE - Method for recovering crack in products having complex shape and being made of steel, glass, ceramics, quartz and other metal, and inorganic material (claimed). ADVANTAGE - The method has simple technique, low cost, and less device investment.
