Intense pulsed electron beams have been applied for surface modification of materials in our laboratory for several years. An improvement of properties like wear, corrosion and oxidation resistance was found. Three different modification modes can be distinguished: rapid melting and solidification, surface alloying of coatings into the bulk and surface fusing of coatings to the bulk. All three surface treatment processes were investigated using the GESA (Gepulste Elektronen Strahl Anlage) facilities having following parameters: accelerating voltage 80-400 kV; power-density 2-6 MW/cm^{2}; beam diameter 4-10 cm; pulse duration 4-250 μs. Such pulses applied on material surfaces lead to a change in microstructure and in the case of surface alloying also to a change in chemical composition. This paper will give an overview on applications in different fields of surface modified materials.
