Abstract
The effect of the structural state formed during laser melting deposition (LMD) on the nitriding of 25Kh13N2 martensitic steel in a glow discharge is investigated. The nitriding of the steel synthesized by LMD is shown to result in a diffusion layer which is twice as thick as that in the steel after martempering. The diffusion layer of the steel synthesized by LMD followed by high-temperature tempering is 1.75 times thicker than that of the steel after martempering. The microhardness distribution across the diffusion layer is flattened in the case of LMD or LMD followed by high-temperature tempering.
