Inconel 718 superalloy was nitrided for 10 h in a
fluidized bed reactor containing Al2O3
particles as the carrier of
the ammonia + nitrogen gas mixture in between 375 and 450°C.
The structural characteristics of the nitride layers and the effect
of nitriding on high temperature wear properties of Inconel 718
superalloy were investigated. A significant increment in surface
hardness (from 495 to 1735 HV) was achieved after nitriding
treatment carried out at 400 °C. The applied nitriding treatment
led to formation of a nitrogen enriched surface layer exhibiting
superior wear resistance at 600 °C when compared to untreated
state of the Inconel 718 superalloy.

CoCr alloys (ASTM F75) are well-known metallic biomaterial which is used in production of load bearing orthopaedic
implants because of their superior mechanical properties [1,2]. Although this material has superior mechanical properties,
low bioactivity and ion release as a result of tribological effects are limiting it’s wider applications [3]. Surface
modification of this material to enhance it’s bioactivity and wear resistance is one of the hot topics in the literature [4,5].
