Tribological properties of plasma nitrided inconel 718

Tribological properties of plasma nitrided inconel 718

Inconel 718 was plasma nitrided using the various controlling parameters such as treatment temperature, treatment time and N2/H2 gas composition. It was found that the case growth rate is proportional to the square root of treatment time. Maximum microhardness of 1290HK which was 3 times harder than...

It was found that the case growth rate is proportional to the square root of treatment time. Maximum microhardness of 1290HK which was 3 times harder than the bulk metal was obtained with 600°C and N2/H2=1/1 after 9 hours of treatment.
