In this paper the possibilities of using Low Pressure Cold Spraying (LPCS) method for filling the casting defects are presented. In Cold Spraying there is no metallurgical bonding because powder particles are deposited in solid state. The effect of high temperature on both substrate and coating structure is avoided. In performed experiments coatings of Al, Zn and Sn powders with addition of Al2O3 ceramic were deposited onto chosen aluminium alloys substrates. Two the most important mechanical properties of Cold Sprayed coatings, i.e. bond strength and microhardness, were analysed. Coatings bond strength was determined by tensile pull test. Coatings microstructure was examined with the use of scanning electron microscope (SEM) analysis. LPCS method potential applications in castings repair is shown.
