| Abstract: |
Cold Spraying, as a novel Thermal Spraying Technology can deposit a wide range of ductile materials on different substrates; a problem arises when the objective is to use this technology to deposit brittle materials such as ceramics in applications where melting must be avoided. One example is when spraying Bio-Ceramics, in which particle´s melting often leads to changes in physical and chemical properties and subsequently resulting in unknown variations in the coating´s biocompatibility. While Non-Ductile Materials can only be deposited if they are co-cold-sprayed with a ductile (matrix) material a Metal-Ceramic Powder Composite must be used for these objectives.
The goal of this paper is to show a transient Non-Linear Dynamics Computational Analysis of a Metal-Ceramic Powders Composite impacting a metallic substrate by the means of Cold Spraying Technology; all this in order to understand the formation of cold sprayed composite coatings while comparing them with experimental results and using ANSYS-AUTODYN© to assess the suitability of this spraying technology for coating special application substrates.
