Back to steel basics.... the hardness that a steel can achieve in heat treatment is dependent on the carbon content. Higher carbon ... higher hardness.
So if carbon is added to the surface of a low carbon steel, a normal quench and temper heat treatment will result in a higher hardness at the surface and a lower hardness in the core just due to the difference in the carbon content.
