Metal-Ceramic Interfaces in Laser Coated Aluminium Alloys [PDF]
, 1993 A novel process was developed to firmly coat an aluminium alloy, Al6061, with α-Al2O3 by means of laser processing. In this approach a mixture of SiO2 and Al powder was used to inject in the laser melted surface of aluminium.

Enhancing printability of 3D printed concrete by using metakaolin and silica fume
Structural Concrete, EarlyView.Abstract This study investigates the effects of incorporating metakaolin (MK) and silica fume (SF) on the fresh and hardened properties of 3D printed concrete (3DPC). Five mix designs were prepared with MK replacement levels of 0%, 10%, 12.5%, and 15%, along with one mix containing 10% MK and 5% SF.
