The present invention is directed to a method for coating a component, wherein the component has a first and a second surface, and wherein the first and the second surface adjoin each other at an edge, in which method i) first of all, the edge between the first and the second surface is rounded, and ii) subsequently, a coating is applied to the first surface.

Method for coating a component

Disclosed is process for producing a wear-resistant coating on a component. The process comprises providing an electrolyte which contains Co and/or Ni, dispersing first particles comprising hard material particles and/or slip material particles in the electrolyte, dispersing second particles comprising metal alloy particles in which the metal alloy comprises chromium and aluminum in the electrolyte, providing a component to be coated in a bath of the electrolyte which has first and second particles dispersed therein, and electrodepositing a matrix of Co and/or Ni with incorporated first and second particles on the component. A correspondingly produced wear-resistant coating is also disclosed.

Wear-resistant coating produced by electrodeposition and process therefor

The present invention relates to a method for the coating of a surface of a TiAl alloy, in which at least one layer is electroplated on the surface of the TiAl alloy, wherein the surface of the TiAl alloy is subjected to an at least two-step surface treatment for the formation of a roughened surface, this treatment comprising at least one electrochemical processing and at least one electroless chemical processing.

Method for the electroplating of TiAl alloys

A method for the pre-treatment of titanium components for the subsequent coating thereof is provided. The method includes at least the following steps: a) etching of the component in an acidic solution containing fluoride and nitric acid (HNO3); b) activation pickling of the etched component in a solution containing at least sodium nitrate (NaNO3) and tetrafluoroboric acid (HBF4); and c) activation of the activation-pickled component in a bath containing acid or in an acidic bath containing nickel.

Method for the pre-treatment of titanium components for the subsequent coating thereof

A method for producing a galvanically deposited protection layer against hot gas corrosion of a structural component, involves immersing the structural component in an electrolytic bath of a cobalt and/or nickel matrix material. Alloying chromium and/or aluminum particles are suspended in the electrolytic bath. Gas bubbles are mixed into the electrolytic bath, and the immersed structural component is rotated in the bath while the galvanic deposition or coating takes place. The bath is stationary and rotation of the structural component takes place about a substantially horizontal axis.

Method for producing a galvanically deposited protection layer against

Galvanically or electrolytically deposited protective coatings are produced on structural components such as gas turbine blades by suspending in the electrolytic solution a metal alloy powder of which the particles have a spherical configuration and a passivated surface. The concentration of the particles in the electrolyte is preferably smaller than 100 g/l, whereby a high insertion rate of up to 45% by volume has been achieved at relatively low costs and small technical efforts.
