Cu, Ni and Al powders mixed in a certain stoichiometric proportion were ground via ball milling and deposited as coatings using low pressure cold spraying (LPCS) technology. The effect of particle morphology on the powder structure as well as the microstructure, composition and mechanical properties of the coatings was studied. The results revealed a coreshell structure of ballmilled powders.
The initial ball milling method is a neat grinding method, which is a method in which the product is directly obtained by directly mixing ball milling with solid raw materials. In 2006, Pichon et al. first synthesized porous MOF copper isotonic acid Cu(INA) 2 by mechanical ball milling. Since then, this method has attracted much attention.
