| titleOfInvention | A kind of metal powder with rough surface, preparation method and application in SLS/SLM technology |
| abstract | The invention discloses a preparation method of metal powder with rough surface, which comprises the following steps: performing oxidation treatment on metal powder to obtain metal powder with an oxide layer on the surface; For the metal powder with rough surface, the present invention firstly oxidizes the metal powder to obtain the metal powder with the oxide layer on the surface, and then pickles the metal powder with the oxide layer on the surface to obtain the metal powder with the rough surface. In the present invention, the metal powder that is difficult to be corroded by acid, such as copper alloy powder, can be reacted with acid through the first oxidation step, so that the surface roughness of the metal powder can be effectively improved, and the reflection mechanism of the metal powder surface is changed from specular reflection to diffuse reflection. Significantly reduces the reflectivity of the metal powder surface to the laser light. |
