Analysis of the Surface of Deposited Copper After Electroerosion Treatment

Resumo

An electron microscope analysis of the surface of deposited copper is performed after a profiling-piercing electroerosion treatment. The deposited copper is treated with steel, duralumin, and copper electrode tools at different pulse energies. The treatment with the duralumin electrode produces on the treated surface a web-like structure and cubic-morphology polyhedral dimples about 10 μm in size. The main components of the surface treated with the steel electrode are developed polyhedral dimples with a size of 10 – 50 μm. After the treatment with the copper electrode the main components of the treated surface are large polyhedral dimples about 30 – 80 μm in size.
