Key Findings
- 01Gas nitriding and quenching (GNQP) at higher temperatures (1223 K) resulted in a surface primarily composed of TiN, while lower temperatures (1023 K) yielded TiO2.
- 02Higher processing temperatures (1223 K) led to increased surface and interior hardness.
- 03GNQP specimens exhibited lower wear amounts compared to the solution-quenched (AQ) specimen.
- 04The coefficient of friction was lower for GNQP specimens processed at 1023 K compared to those at 1223 K.
- 05Surface constituents and roughness influenced wear at lower loads (500 g), while the nitride layer and damping capacity were more critical at higher loads (3000 g).

Variables
Strengths & Limitations
Strengths
- +Direct comparison with a baseline (AQ specimen) allows for clear assessment of the treatment's effect.
- +Investigation of multiple process parameters (temperatures) provides a nuanced understanding of their impact.
Limitations
The specific temperatures and durations of the gas nitriding and quenching process might not be directly transferable to all design contexts. The study's focus on a single alloy composition limits generalizability.
