Abstract [en]

Variety of P/M alloys, which are characterized by optimized mechanical properties, find increasing applications on large scale in various industries. The type of application basically depends on the material compatibility vis-a vis application, which in turn, is based on the chemical natural and the P/M manufacturing route. Often, the P/M alloys are subjected to termochemical treatment in order to increase their surface hardness and wear-resistance. In the present experiments P/M intermetallic alloys of the type FeAl and FeAlNi have been prepared by conventional powder metallurgy via compacting and sintering. The surface hardness was improved by nitriding. The mapping of the microhardness profiles and structural examination of nitrided P/M alloys have been performed. The influence of the technology parameters on the development of nitrided layers of P/M alloys is discussed.
