Abstract

For the modification of an automotive cylinder block, two types of water-atomized cast iron powders were deposited onto an aluminum alloy substrate by atmospheric DC plasma spraying. The wear-corrosion characteristics of the coatings were investigated by means of a wear test and EIS. The pre-annealed and graphitized coating improved the wear-corrosion resistance in a deaerated 0.5M H2SO4 solution.
