Abstract A friendly technology with the environment which consists of the elaboration of carbon steels through specific proceedings to powder metallurgy has in view the contribution of methane gas in iron powders at the same time with sintering. This technology is advantageous from various points of view: the final product is a part which does not need afterward processing with solid waste result and therefore the specific energy consume is lower, the wear and corrosion behavior is similar to...

AbstractConsidering the advantages of steel surface hardening, when less expensive low- and medium- carbon steels can be surfacehardened without the problems of distortion and cracking associated with the through hardening of thick sections, we developedsome research entailing the increase in environmental performance of iron powders carburizing process using methane as carrier.Apart of studies on optimal working parameters and methods, our research addresses improvements in environmentalperform...
