    Abstract

    A laser-based technique was employed to deposit Fe 3O 4 on A319Al. The technique produced a Fe 3O 4/Al composite coating with extremely refined microstructure. Scanning Auger microscopy indicated reaction between oxide particles and aluminum forming Fe-Al intermetallic compounds and Al 2O 3 and intermediate phases. Analysis of coated surfaces fractured in vacuum, indicated substantial toughness of the material due to extremely refined microstructure with finely dispersed oxide and intermetallic compound and/or intermediate phases thereof.
