Abstract
FOR some years it has been known that it is possible to tin aluminium and its alloys by subjecting their surface to the action of intense ultrasonic vibration at the same time as molten solder is applied1–3; but the mechanism for this effect does not seem to have been studied. We have now established that the process is one of removing the oxide skin by cavitation erosion.
