Laser surface treatment processes are very modern technology that allows the properties of the base metal to
remain intact while changing the surface properties. While the mechanical properties of the base metal meet
the design needs, the need to develop properties such as corrosion resistance, roughness, hydrophobicity,
hardness and cavitation resistance which is significantly dependent on hardness can be met by this method.
Ship propellers are frequently exposed to cavitation erosion as they operate at high speeds in sea water, which
is an ionic and corrosive environment. On the other hand, the roughness of the propeller surface and its
hydrophobic properties which are largely affected by the roughness values, significantly affect the ship's
resistance. In this study, the changes in the roughness, hardness and hydrophobic properties of the surface of
bronze propeller material samples were investigated by using laser surface treatment methods. A super
hydrophobic surface has been obtained.
