摘要：

This study explores the potential ability of laser metal deposition (LMD) as metal foaming process, considering that its intrinsic high heating/cooling rates can avoid some of the common problems of gas leakage, in-homogeneity and anisotropy that arise when manufacturing metallic foams by conventional powder metallurgy (PM) methods. Highly porous coatings of aluminum and titanium alloys have been obtained by this PM-LMD metal foaming method.
