Pack nitriding of aluminium using cassava waste

Abstract

Pack Nitriding is a process analogous to pack carbonizing. In this work, cassava leaves were employed as a source of nitrogen. Upon heating, slow decomposition of the compound provides Nitrogen, the Nitrogen was allowed to interact with aluminium metal surfaces, which were packed nitrided at temperature of 350°c. The time duration varied from 1 hour to 6 hours. It was observed that there was an increase in strength and hardness of aluminium. Therefore, a nitriding of aluminium using cassava leaf as a source of nitrogen is assessed possible.
