Laser-Based Repairing of Turbine Airfoils and its Economical and Environmental Impact
By J. Michael Wilson Purdue University Replacement costs for high value engineering components are very high due to long lead times and special tool required for processing high strength materials. Laser direct deposition provides an attractive and cost effective means for repairing or remanufacturing high value engineering components. Traditional repair processes are limited in applicability […]
ICALEO 2011 Wrap-up: From Attoseconds to Zettawatts
ORLANDO, FL, November 7, 2011 — From attoseconds to zettawatts, the 30th-annual International Congress on Applications of Lasers & Electro-Optics looked once again to the future with another powerful conference packed with cutting-edge research from around the world. The message of the Laser Institute of America’s premiere conference — which returned to LIA’s hometown of Orlando — was clear: […]
Laser Direct Deposition of Nickel-Based Metal Matrix Composition
By Kevin C. Schoeffel and Yung C. Shin, Center for Laser-based Manufacturing, School of Mechanical Engineering, Purdue University, West Lafayette, Indiana Ceramic particulate reinforcement enhances the already superior mechanical properties of nickel-based super alloys. Reinforcement particles alter the matrix microstructure of the metal matrix composites (MMC) to improve wear resistance, hardness, etc. Laser direct deposition […]
The Long Awaited Revised Z136.3 is Coming! Reserve Your Copy Today!
Revision of the Z136.3 was driven by the movement of the widespread use of medical lasers – from hospital operating rooms to the office and/or clinic environment. In an effort to acknowledge the diversity of laser therapy applications and practice setting locations, the title of the standard has been changed to “Safe Use of Lasers […]
