Emissions from metallic powder and high energy-based process - thermal spraying knowledge refresh

subject

description

International audience; Recently, in different industrials sectors, emissions are subjected to rules and regulations which are coming increasingly stringent and more carefully monitored. And this is where thermal spraying, powder atomization and additive manufacturing come in metal powder and high energy-based processes. These technologies manufacture or use micrometer size feedstock. But the process characteristics as the heat source induces nanoparticle formation. The paper is to address a knowledge refresh on thermal spraying regarding emissions due to the process in relationship with working conditions, personal protection, dust filtration, etc. A survey has been conducted and the results are compared to scientific literature and previous surveys.
