| titleOfInvention | A method for reducing the surface brittleness of hard and brittle materials |
| abstract | The invention relates to a method for reducing the surface brittleness of hard and brittle materials. The method comprises the steps of: (1) dissolving a thermoplastic polyurethane elastomer in a solvent, then adding modified graphite nano-powder, and ultrasonically oscillating to obtain a toughening solution, spare. (2) Immerse the workpiece of hard and brittle material to be treated in the toughening solution, then perform ultrasonic vibration treatment, and then perform electron beam irradiation treatment on the workpiece after taking out the workpiece. In the present invention, a toughening solution is prepared by using thermoplastic polyurethane elastomer with good toughness ability and modified graphite nano-powder as raw materials. After infiltration and electron beam irradiation treatment, a tough film is penetrated on the surface of a hard and brittle material workpiece to form a tough film. The thermoplastic polyurethane elastomer and modified graphite nanoparticles in the toughening solution penetrate into the microcracks on the surface of the workpiece under the action of ultrasonic oscillation, and are cross-linked by irradiation to form a gel elastomer, which can well overcome the collapse damage. The problem. |
