Laser Cleaning of Carbonaceous Deposits on Combustion Engine Components
By Yingchun Guan, Chih-Hsing Liu, Gnian Cher Lim, Hong Yu Zheng and Ming Hui Hong Carbonaceous deposits covering the surfaces of combustion engine components are known to cause abrasive wear, leading to increased oil consumption and reduce engine durability as well as performance. Remanufacturing is the process acting on end-of-life products to recover manufacturing standards and […]
Direct Metal Deposition of Functional Graded Material
By J. M. Amado, J. N. Montero, M. J. Tobar, A. Yañez Functionally graded materials (FGM´s) are usually described as composite materials in which composition and structure varies gradually from one point to another. Traditional composites are based on homogeneous mixtures where the properties of the respective components are averaged according to their relative proportion. […]
From dental and bone implants to restoration of engine parts, additive manufacturing changing lives and industries
Two weeks ago today, the sixth-annual Laser Additive Manufacturing Workshop opened in Houston with a riveting keynote by GE Aviation’s Todd Rockstroh. Setting an attendance record, LAM 2014 closed the following day with a lively Q&A session on the qualities and varieties of AM alloys for powder-bed and powder-fed applications. It’s always illuminating to go […]
