SALDVI of SiC into Metal and Ceramic Powders

Selective Area Laser Deposition Vapor Infiltration (SALDVI) is the SFF technique using gas phase precursors to locally infiltrate a powder bed into a desired shape. Experiments were performed with a CO2 laser and the silicon carbide forming gas precursor Si(CH3)4. This paper will report on the microstructural aspects of SiC into a variety of metal and ceramic powders including Mo, SiC, ZrO2, and WC.The authors acknowledge the support for this research by the Office of Naval Research (grant #N00014-95-1-0978).Mechanical Engineerin
