| titleOfInvention | A kind of low laser reflectivity powder particle and preparation method |
| abstract | The invention belongs to process for treating surface, it is related to the powder particle and preparation method of a kind of high sphericity, antiradar reflectivity.It has spherical inner core and is covered in the graphite flake clad on spherical inner core surface powder particle of the invention, and the spherical inner core is aluminum particle, copper powder particle or Ni-base Superalloy Powder particle；Graphite flake coating thickness is 100nm~5um.The preparation step of powder particle of the present invention is: powder washing；Prepare nano-catalyst particles；Graphite flake deposition.The invention proposes a kind of high sphericities, the powder particle and preparation method of antiradar reflectivity, the high sphericity of particle kernel can be kept, to ensure that the performance of block after the powder metallurgy formings such as 3D printing under the premise of reducing laser reflectivity. |
