Corrosion Behavior of Inconel 625 Coating Produced by Laser Cladding

Anti-corrosion properties of Inconel 625 (In) laser cladding coatings onto the (S235JR) steel (S) were investigated. The produced with use wire (WIn/S) or powder (PIn/S). mechanical characterized by microhardness measurements. PIn/S shows highest hardness. surface and microstructure specimens observed a scanning electron microscope (SEM). analysis energy-dispersive spectroscope (EDS) indicated that structure WIn, PIn depend on its production technique. WIn have dendritic columnar character. Corrosion test materials carried out using electrochemical methods. corrosive environment was acidic chloride solution. It turned coating, which method powder, has best anti-corrosion in an aggressive environment.
