| Abstract: |
| In this research, the spherical shape composite powder was prepared with spray drying through adding a type of high polymer dispersant in Cr3C-25 % NiCr slurry. The experiment researched the effect of dispersant content on the characteristics of Cr3C2-25 % NiCr composite powder by means of SEM. The result indicats that the properties of Cr3C2-25 % NiCr slurry are accommodated obviously,and that the pourability and loose density of powder are increased. When the content of dispersant is 0.04 %, the powder is of best physical properties. |
