| Abstract Scope |
Cemented carbides such as Tungsten Carbide (WC) are known for their use in resilient wear-resistant applications. However, conventional manufacturing WC can become cost and time ineffective. Additive manufacturing (AM) is a favorable method for cemented carbide manufacturing with complex geometries and less cost and time intensive compared to alternate techniques. This project applies a method to measure cemented tungsten carbide (WC)-17 wt.% nickel (Ni) composite melt pool temperatures in laser powder bed fusion (L-PBF) using a high-speed color camera two-color method technique. Using the two-color method, melt pool thermal maps of WC-Ni were captured with varying process parameters. Thermal models for the cermet composite were validated by the images to understand the underlying physics taking place in the melt pools. Melt pool temperatures exceeding melting of WC and Ni were observed. The steps taken to thermal model WC-Ni can be applied to other composite materials. |
