Abstract (en)

[origin: WO2007003160A1] The invention relates to a method for producing an armor plating (14) on the tip of a blade (10) of a turbomachine, especially on a rotating high-pressure compressor blade of a gas turbine. Said method comprises the following steps: a) a blade (10) made of a basic nickel material is provided; b) a basic nickel solder is applied to a tip (13) of the blade (10); c) hard particles that are made of cubic boron nitride and are coated with titanium or a basic titanium material are applied to the solder; d) the solder is fused on in a vacuum so as to obtain a matrix which at least partly surrounds the hard particles; e) the armor plating (14) of the blade tip is fixed by means of a cooling process.
