Present competitive world is looking for Components with high strength and fatigue resistance finding their applications in aerospace, turbine parts and especially bio-medical devices with high bio-compatibility. Advanced surface engineering techniques are required to produce parts of higher complexities and desirable surface qualities. Laser peening stood first in a row of all various surface treatments of metallic component. This paper discusses about the mechanical properties like hardness and roughness then the surface morphology and the corrosion behaviour of the laser peened titanium samples with and without coating. © Published under licence by IOP Publishing Ltd.

Investigation of Mechanical, Microstructural and Corrosion behaviour of Titanium subjected to Laser Peening with and without Ablation

Implants made out of Ti alloys often fail due to their lower wear and corrosion resistance. In order to obviate this problem, submicrometric diamond films were grown on Ti-13Nb-13Zr and Ti-23Nb-0.7Ta-2Zr-O (Gum metal) using hot filament chemical vapor deposition technique. Deposited films were characterized using XRD, Raman, SEM, AFM and nanointender. The electrochemical corrosion and reciprocatory wear behavior of the coated samples were evaluated in simulated body fluid. The results demonstrate that corrosion and wear properties of the diamond coated Gum metal are far superior than Ti-13Nb-13Zr alloy, due to the presence of beta phase in the former alloy. © 2012 Elsevier Ltd.
