The study investigates the wear resistance of nitrided ShKh15 steel in an abrasive environment after glow-discharge nitriding in hydrogen-free nitrogen–argon atmospheres. The influence of technological parameters, including pressure and argon content, on the thickness, hardness, phase composition, and hardness gradient of nitrided layers was analyzed using a two-factor rotatable design. Empirical mathematical models describing nitrided layer properties and wear behavior were developed. Experimental results showed that wear resistance, surface hardness, and layer thickness can be controlled and optimized by varying nitriding conditions. The highest wear resistance was achieved under optimal nitriding conditions, significantly exceeding that of quenched steel.
