Additive and subtractive laser-pulsed nano/micro machining of metal alloys for enhanced material properties, and numerical validation
Bashir, Mahmood Al (Wichita State University, 2020-05)This research focuses on two different aspects of laser machining process, namely additive and subtractive laser micromachining, for inherent improvements to metallic surfaces. In both the processes, material surfaces are ... -
Femtosecond laser Nanotexturing of drug-eluting stents
Bashir, Mahmood Al (Wichita State University, 2017-04-28)Stents have been used for over a decade to treat coronary arteries affected by stenosis, a state where the arteries are narrowed by the deposition of plaque. But studies have found restenosis can hinder its purpose. ... -
Nanosecond pulsed laser surface nanotexturing of tantalum: Correlation between diffusion length model and experimental observations
Bashir, Mahmood Al; Nair, Rajeev (Laser Institute of America, 2019-05-01)The diffusion length of surface textured tantalum using AVIA 355® nanosecond laser was correlated with the different laser parameters. The material was cut into 1 × 1 cm 2 coupons and was exposed to the laser beam of various ... -
Numerical study and experimental comparison of laser cutting of 1.2MM thick austenitic stainless-steel using CW Nd: YAG laser
Atayo, Asonganyi; Bashir, Mahmood Al (Wichita State University, 2020-05-01)Stainless steel-304 is the most common steel used for corrosion resistance applications, but higher melting point is a limitation in industrial manufacturing. The non-conventional and subtractive manufacturing technique ...
