Investigation of pore structure in cobalt chrome additively manufactured parts using X-ray computed tomography and three dimensional image analysis

July 15, 2017

Author(s)

Felix Kim, Edward Garboczi, Shawn P. Moylan, John Slotwinski

Pore structures of additively manufactured metal parts were investigated with X-ray Computed Tomography (XCT). Disks made of a cobalt-chrome alloy were produced using laser-based powder bed fusion (PBF) processes. The additive manufacturing processing

INVESTIGATION OF PORE STRUCTURE AND DEFECTS OF METAL ADDITIVE MANUFACTURING COMPONENTS USING X-RAY COMPUTED TOMOGRAPHY
