Abstract
The invention relates to a turbomachine blade (10), in particular a gas-turbine blade, having a blade aerofoil (11) which has a flow leading edge (13) and a flow trailing edge (14), with a suction side and pressure side of the blade aerofoil extending between the flow leading edge and the flow trailing edge. According to the invention, the blade aerofoil (11) is coated at least in the area of the flow leading edge (13) with a ductile wear-protection layer, with the ductile wear-protection layer having ceramic hard particles incorporated in a metal matrix.
