Abstract

The invention relates to the technical field of laser surface modification, in particular to a laser quenching light-absorbing coating and a preparation method thereof, and the laser quenching light-absorbing coating is prepared by mixing a solvent and aggregate; the solvent comprises the following components in parts by mass: 5-12 parts of a binder; 0.2-0.8 part of an anti-settling agent; 0.02-0.60 part of a thickening agent; 0.10-1.60 part of a wetting agent; 0.1-3.0 part of a leveling aid; 4.0-16.0 parts of a diluent; 0.02-0.60 part of a dispersing agent; 10-60 parts of anhydrous alcohol; 40-100 parts of distilled water. The coating can improve the laser absorptivity of a metal material, avoids local burn of a workpiece, guarantees the machining quality of the workpiece, and improves the hardness of the workpiece.

Description

technical field [0001] The invention relates to the technical field of laser surface modification, in particular to a laser quenching light-absorbing paint and a preparation method thereof. Background technique [0002] Laser quenching is an effective surface modification technology, and its characteristics of rapid heating and rapid cooling cannot be compared with traditional heat treatment technology, so it is widely used in many fields. Limited by the influence of metal materials on the reflectivity of the laser as high as 20% to 40%, the laser energy cannot be fully utilized, and the reflected energy will cause harm to the health of the field operators. Therefore, in the process of surface laser quenching, it is particularly important to improve the energy absorption rate of laser irradiation of metal materials, so as to make full use of laser energy, reduce production costs and improve production efficiency. In recent years, pre-installing light-absorbing materials on ...
