摘要: A method for epitaxial addition of repair material onto a process surface ( 38 ) directionally solidified component 30 ). The is positioned in fluidized bed 34 to drift particles over the as laser energy 36 rastered across melt and fuse entire simultaneously. moved downward 39 direction parallel grain orientation added surface, thereby providing continuous without recrystallization.
