Abstract
Disclosed is a process for producing a wear-resistant layer, in particular on components of gas turbines or aero engines. The process comprises providing a component with a titanium material on at least part of a surface on which the wear-resistant layer is to be produced, applying a solder formed from a cobalt base material to the titanium material, soldering the solder to the titanium material by applying heat and producing at least one diffusion zone between solder and titanium material which comprises intermetallic phases.

A process for producing a wear-resistant layer on a component, wherein the process comprises:
- providing a component which comprises a titanium material on at least part of a surface of the component on which the wear-resistant layer is to be produced,
- contacting the titanium material with a solder in the form of a paste or semifinished product formed from a cobalt base material,
- soldering the solder to the titanium material by applying heat to thereby produce one or more diffusion zones between solder and titanium material, which one or more diffusion zones comprise one or more intermetallic phases and form the wear-resistant layer, the soldering being carried out at a temperature of from about 1100° C. to about 1200° C.
A process for producing a wear-resistant layer on a component, wherein the process comprises:
- providing a component which comprises a titanium material on at least part of a surface of the component on which the wear-resistant layer is to be produced,
- contacting the titanium material with a solder in the form of a paste or semifinished product formed from a cobalt base alloy which comprises from 6.5% to 7.5% by weight tungsten, from 3% to 4% by weight tantalum, from 22.5% to 24.35% by weight chromium, from 0.55% to 0.65% by weight carbon, from 9% to 11% by weight nickel as well as titanium and zirconium, remainder cobalt,
- soldering the solder to the titanium material by applying heat to thereby produce one or more diffusion zones between solder and titanium material, which one or more diffusion zones comprise one or more intermetallic phases and form the wear-resistant layer.

- providing a component which comprises a titanium material on at least part of a surface of the component on which the wear-resistant layer is to be produced,
- contacting the titanium material with a solder in the form of a paste or semifinished product formed from a cobalt base material,
- soldering the solder to the titanium material by applying heat to thereby produce at least two diffusion zones between solder and titanium material, one diffusion zone comprising about 11% by weight chromium, about 4% by weight nickel, about 13% by weight molybdenum, about 2% by weight silicon, about 13% by weight titanium, about 8% by weight aluminum and about 1% by weight niobium, remainder cobalt, and another diffusion zone comprising about 21% by weight chromium, about 12% by weight molybdenum, about 1% by weight silicon, about 12% by weight titanium, about 6% by weight aluminum and about 1% by weight niobium, remainder cobalt, which at least two diffusion zones comprise one or more intermetallic phases and form the wear-resistant layer.
