A　Cu-10Fe　alloy　with　magnetron　sputtered　Al　films　was　irradiated　by　high　current　pulsed　electron　beam　(HCPEB)　with　various　pulse　numbers,　next　changes　of　its　microstructure　and　corrosion　property　were　investigated.　Compared　with　the　initial　sample,　microhardness　and　corrosion　resistance　of　the　aluminized　Cu-10Fe　alloys　after　the　HCPEB　treatment　are　remarkably　improved　with　increasing　pulse　numbers.　This　improvement　could　be　attributed　to　formation　of　Al2Cu　intermetallic　compounds,　occurrence　of　liquid　phase　separation　and　grain　refinement　in　the　surface　layer　of　the　Cu-10Fe　alloy　during　the　process　of　rapid　remelting　and　solidification　induced　by　the　HCPEB　treatment.
