Abstract:
1. A process for producing a metallic component, comprising: projecting first particles comprising iron as a main component and having an average particle size of not less than 0.1 mm and not more than 5 mm onto a surface of a metallic material comprising a lightweight alloy; and following completion of said projecting of the first particles, projecting second particles comprising essentially no iron and having an average particle size of not more than 200 μm onto the surface of the metallic material, wherein in said projecting of the first particles, the first particles are projected at an intensity not less than 0.10 mmA and not more than 0.30 mmA, expressed in terms of an arc height value determined using an Almen gauge system, and at a coverage not less than 100% and not more than 1,000%, in said projecting of the second particles, the second particles are projected at a coverage not less than 100% and not more than 1,000%, a spray speed of the first particles and a spray speed of the second particles are regulated by a spray pressure of a compressed air stream, and the spray pressure in said projecting of the first particles is not less than 0.1 MPa and not more than 1 MPa.
