DOI: 10.1016/j.ceramint.2017.11.013
Abstract: Abstract Laser additive manufactured zirconia-alumina ceramic (ZrO2-Al2O3) parts demonstrate severe problems resulting from cracking and inhomogeneous material dispersion. To reduce these problems, we propose a novel ultrasonic vibration-assisted laser engineered net shaping (LENS) process for… read more here.
