Surface strengthening of structural steels with carbon nanomaterials using laser and electron-beam heating is studied. It is shown that during laser treatment the maximum microhardness of a modified layer is achieved in a strengthened zone up to 70 μm thick with q = 9 × 104 W/cm2, and with electron beam treatment in a strengthened zone up to 300 μm thick with q = 4.6 × 104 W/cm2. It is established that in both cases with optimum treatment regimes strengthening is due to forming martensite, a cellular structure, and grain disintegration.
