Influence of Mechanical Activation of Powder on SLS Process

Article Preview

Abstract:

The paper presents the results of the experiment, describing the effect of mechanical activation of powder Cu and Ni on the nature of their SLS-sintering method. The changes in structure and bulk density of powders after mechanical activation are revealed, which generally has a positive effect on the synthesis process of a product.Intorduction
