Reduced wear and adhesion forces by laser dispersing of ceramics

Laser dispersing offers a great potential to fabricate layers or tracks with tailored properties threat duce abrasive or adhesive wear at the surface of highly stressed components. Different ceramic powder materials like aluminum nitride, aluminum oxide and titanium carbide have been embedded in the surface of tool steels using laser dispersing. The created layers were investigated regarding their elemental composition, dimension, particle distribution and hardness curve.
