A method of treating a cast metal matrix, the method comprising steps of depositing a self-fluxing first layer of material on an outer surface-connected void of the cast metal matrix, depositing a second layer of material on the cast metal matrix thereby closing off the outer surface-connected void so that the outer surface-connected void is an effective internal void, and hot isostatic pressing the cast metal matrix so that the self-fluxing first layer facilitates healing the effective internal void and complete metallurgical bonding of the surfaces of the outer surface-connected void.
