Abstract:
1. A powder for cold spraying processes which comprises microparticles, nanoparticles and coupling molecules, wherein the nanoparticles are bonded to one of the microparticles by at least one coupling molecule, the coupling molecules are dendrimers having a tree-like structure with an unbranched end and a branched end, the unbranched end of the tree-like structure bearing a functional group bonded to the one of microparticles, and the branched end of the tree-like structure bearing functional groups bonded to the nanoparticles, wherein the dendrimers are oriented substantially normal with respect to the surface of the one of microparticles such that the functional groups bonded to the nanoparticles extend outward from the microparticle.
