Resumo
Biomaterial powders are in high development due to expansion of additive
manufacturing (AM) processes. Selective laser melting (SLM) is a particular
AM technology, which completely melts a powder bed layer by laser beam.
Investigations of appropriated physical properties of feedstock (powder alloy)
were the aim of this study. Cobalt-chromium-molybdenum (Co-Cr-Mo) alloy
was used to overview of gas-atomized powder properties in different granulometric
ranges (D1 12 - 19 μm, D2 20 - 46 μm and D3 76 - 106 μm), as their:
physical, chemical properties and thermal analysis. SLM manufactured standard
tensile specimens of usually granulometric range powder size provided
mechanical, chemical and thermal properties of biocompatible Co-Cr-Mo alloy.
The physical properties showed that powders in the range of 20 to 50 μm
provide a better flow ability and packed density, which are relevant characteristics
to SLM processing. Manufacturing by SLM process provided suitable
mechanical properties in the health area, as well as, maintained the biocompatible
properties of the Co-Cr-Mo alloy.
