The diagram compares the particle velocity and gas temperature ranges of cold spray and other thermal spray processes: In the cold spray process, the gas and particle temperatures are much lower and the gas and particle velocity are much higher than in other thermal spray processes.
How cold spray technology improves the electrical and erosion properties of polymers
Metallization of polymers is an attractive way of improving their electrical and erosion properties, but it is still challenging to achieve a dense metal coating on polymer surfaces by thermal spray processes, due to excessive surface erosion during processing.
Super-fast high-energy X-rays reveal defects in 3D printed products as they are being built
Engineers from Carnegie Mellon University and Argonne National Laboratory report that they have discovered defects in the products of the Laser Powder Bed Fusion (LPBF) process by taking videos of the products with super-fast high-energy x-rays as they are being built.
One Minute Mentor: Austenitizing ductile cast iron
The usual objective of austenitizing is to produce an austenitic matrix with as uniform a carbon content as possible prior to thermal processing. The graph shows the 2% silicon section of the Fe-C-Si phase diagram.
