Aiming at the shortcomings of surface properties of CuW60 tungsten-copper alloy under extreme working conditions, laser modification technology was used to explore its influence on surface roughness and mechanical properties of the alloy. By finely adjusting the laser parameters, the microstructure, composition change of the modified layer and its correlation mechanism with the properties were analyzed. It is found that laser modification can significantly adjust the surface roughness of the alloy and enhance its mechanical properties such as hardness, which provides a new idea and method for improving the comprehensive properties of such materials. These rusults not only enriche the theoretical system of laser surface engineering technology, but also expand the application space of CuW60 tungsten copper alloy in the field of high-end manufacturing.
