The Preparation and Experimental Research for Inner Cladding Casting of Al-Al

Abstract

With the rapid development of science and technology, the unceasing enhancement of component integration degree, and the increasingly demanding of parts using conditions, the part that the traditional metal materials and alloy materials preparation is hard to meet the requirements of the use of some special conditions, so the new composite materials have been paid attention to by the countries all over the world. An casting method for Inner Cladding Casting was introduced. By the use of this method, the Al-Al inner cladding casting which has the transition layer in the middle was prepared, it was indicated that the casting method for inner cladding casting has the feasibility. Through the soaking experiments of three group samples which were Arc Spraying Al layer、substrate of Al and Inner Cladding Casting of Al-Al, we find out that by 140h soaking experiments for inner cladding casting of Al-Al the porosity change was little and it had shown very good corrosion resistant effect.
