Research on the Reduction of Greenhouse Gases Emissions to the Enrichment in Carbon of the Iron Powders

Abstract

Abstract. The steels elaborated through proceedings that are specific to powder metallurgy have as raw material the iron powder which is enriched in carbon through various proceedings: carburizing in a methane-bearing atmosphere or in a liquefied petroleum gas (LPG)-bearing atmosphere, with the addition of synthetic cementite. In order to be developed as environment friendly technologies, there are made researches in order to reduce GHG emissions.
