Abstract

The absorption of laser radiation of powder materials based on copper and nickel is studied. The dependence of the temperature of the powder material on the power of the incident laser radiation is obtained. A comparison of the values obtained by different measurement methods is presented.

Highlights

  • With selective laser melting (SLM), the properties of the deposited layer, such as uniformity, density, contact with the surface of the part, depend on a number of technological parameters: power density in the laser spot, scanning speed over the surface, nature of the filing of the deposited material, fractional and chemical composition, as well as the absorption capacity of the deposited material [1]
