The article describes the properties of wear resistant electrospark coating made of nanocrystalline alloy of type 5BflCP (Finemet). It is proved that electrospark coating has nanocrystalline structure which is like amorphous matrix with nanocrystals a — Fe. Coating thickness is 33 p, micro-hardness is 8461 - 11357 MPa, wear resistance is 0,55x10~4s/g. Coating ofhanocrystalline alloy of type 5БДCP can be used to increase wear resistance of machinery working surfaces.
