Method for producing a cast iron part with increased corrosion resistance and/or wear resistance, and the cast iron part obtained by said method

A method for producing a cast iron part comprising: a) obtaining a reactive paint comprising at least one first metallic material and at least one binder; b) applying the reactive paint to a sand mould; c) drying the sand mould at least partially coated with reactive paint; d) casting a cast iron melt to obtain a cast iron part comprising at least one surface portion modified with the first metallic material; e) conditioning the cast iron part; and f) depositing at least one layer of a second metallic material on at least one of the surface portions modified with the first metallic material by laser directed energy deposition (L-DED), wherein said second metallic material is an anti-corrosion material and/or an anti-wearing material. A cast iron part obtained by said method.
