2 improvement against oxidation buildups brought about by nitriding super alloy according to this invention oxidation tests at 900 u00b0 c for 24 0 hours in laboratory air of the nitrided specimens of inconel 600 and the counterpart untreated specimen were conducted and the nitrided specimen exhibited a 0 0323 weight gain versus a 0 0406 weight gain for the untreated specimen this represents a 20 44 improvement against oxidation buildups brought about by nitriding super alloy according to this invention oxidation tests at 900 u00b0 c for 24 0 hours in laboratory air of the nitrided specimens of inconel 600 and the counterpart untreated specimen were conducted and the nitrided specimen exhibited a 0 0358 weight gain versus a 0 0659 weight gain for the untreated specimen this represents a 45 7 improvement against oxidation buildups brought about by nitriding super alloy according to this invention while the benefits of nitriding have long been known it does not seem apparent to nitride any of the noted super alloys in order to improve the physical properties of the respective super alloy for example one accepted theory why certain super alloys are so resistant to corrosion is because of the presence at the surface of the retarding additives chromium for example one might anticipate then that any surface treating of a super alloy specifially by nitriding would allow the nitrogen atoms to take the chromium away.
