Afrl-rx-wp-ja-2017-0165 Laser Surface Melting of Stainless Steel Anodes for Reduced Hydrogen Outgassing (postprint)

Anodes of 304 stainless steel have been processed by a continuous wave Yb fiber laser with a wavelength of 1.064 lm and subjected to 50 keV electron bombardment in order to determine the extent to which hydrogen outgassing is reduced by the laser surface melting treatment. The results show a reduction in outgassing, by approximately a factor of four compared to that from untreated stainless ste...

The Interaction between Hydrogen and Surface Stress in Stainless Steel

This paper reveals the interaction between hydrogen and surface stress in austenitic stainless steel by X-ray diffraction stress measurement and thermal desorption analysis before and after being charged with hydrogen. The surface residual stress was varied by surface finishing using several disc polishing agents. The obtained results show that the residual stress near surface had a significant...

Characterization of a Laser Surface-Treated Martensitic Stainless Steel

Laser surface treatment was carried out on AISI 416 machinable martensitic stainless steel containing 0.225 wt.% sulfur. Nd:YAG laser with a 2.2-KW continuous wave was used. The aim was to compare the physical and chemical properties achieved by this type of selective surface treatment with those achieved by the conventional treatment. Laser power of different values (700 and 1000 W) with four ...

A Review on Surface Treatment of Stainless Steel Orthopedic Implants

It is expected that in future, there will be an immense usage of implantable devices which will cause the number of infections to increase naturally because some patients are unable to autonomously prevent formation of bio film on implant surfaces. The ideal implant should be able to promote osteointegration, deter bacterial adhesion and minimize prosthetic infection. Recent developments in mat...
