Abstract
A method of treating a metallic surface comprising a copper alloy, such as phosphor bronze, whereby the metallic surface is ablated by directing a laser beam with a diameter of 200-400 μm produced by a COlaser with a pulse frequency of 1200-1800 HZ onto the metallic surface, and a Nassist gas is concurrently applied with a pressure of 550-650 KPa co-axially with the laser beam to form an ablated metallic surface comprising microgrooves with CuN present on a surface of the microgrooves, wherein the ablated metallic surface has a higher surface hydrophobicity than the metallic surface prior to the ablating.
