20110300408 | METHOD AND DEVICE FOR PRODUCING LOW-WEAR HARD COATINGS - The present application relates to a method and to a device for producing a low-wear nickel and boron-containing hard coating on a metal surface. In the method according to the invention, boron or boron compound particles are dispersed in a nickel-containing electrolyte by way of gases flowing through the electrolyte. The gas flows through a liquid impermeable but gas permeable area of the container floor into the electrolytes and disperses the particles present in the electrolytes. | 12-08-2011 |
