Abstract

Laser treatment of pre-prepared titanium alloy surface is carried out and electrochemical response of the treated surface is analyzed. B₄C particles are located in a carbon filmat the workpiece surface prior to the laser treatment process.Morphological and metallurgical changes are examined inthe laser treated layer using analytical tools. Potentiodynamictests are carried out to assess the corrosion rate ofthe treated surface. It is found that the laser treated surfaceis free from large-scale asperities such as large size cracksand cavities. Laser treatment significantly improved thecorrosion resistance of the surface. The presence of B4Cparticles contributes to microhardness enhancement at thetreated surface; however, the particles do not demonstrateany adverse effect on the corrosion resistance of the surface.&COPY Carl Hanser Verlag GmbH & Co.
