  • Method for Producing Wear-Resistant and Fatigue-Resistant Edge Layers in Titanium Alloys, and Components Produced Therewith
    Publication number: 20080011391
    Abstract: The invention relates to edge layer finishing of functional components, and thereby in particular to a method for producing wear-resistant and fatigue-resistant edge layers in titanium alloys, and components produced therewith. The method according to the invention for producing wear-resistant and fatigue-resistant edge layers in titanium alloys by means of laser gas alloying is essentially characterized in that the laser gas alloying is carried out with a reaction gas that contains or releases interstitially soluble elements in the titanium alloy used, whereby the partial pressure of the reaction gas is selected such that the partial pressure remains below the threshold value above which nitride, carbide, or boride titanium phases are produced.
