Gold plating on stainless steel is extensively utilized in the electronics industry. Chemical gold plating, a prevalent method for preparation, offers advantages such as being straightforward process. However, it often suffers from performance issues, particularly low adhesion strength, which hinders its widespread adoption. This study employs laser-induced chemical deposition process to fabricate localized thin coating 316L stainless-steel substrate using an ammonium sulfite gold-plating solution. The mechanisms of induced and interface bonding are examined, parameter optimization tests conducted with surface morphology evaluation criterion. research demonstrates that laser-directed removal oxide film surface, coupled remelting activation, facilitates exchange reaction between Fe, Cr, Ni, other elements activated area Au(SO3)23–. successfully deposits continuous dense film. A transition layer, approximately 1 μm thick, forms due remelting, resulting amorphous Au–316L alloy. layer enhances substrate, achieving strength 15.2 MPa, comparable 15.9 MPa electrochemical (LECD) coatings. In contrast, (ECD) coatings less than 0.5 MPa.

Gas-induced porosity is almost inevitable in additively manufactured aluminum alloys due to the evaporation of low-melting point elements (e.g., Al, Mg, and Zn) encapsulation gases hydrogen) during multiple-phase reaction melt pool. These micropores are highly unstable post-heat treatment at elevated temperatures greatly affect mechanical properties service reliability. In this study, AlSi10Mg samples prepared by LPBF were subjected solution heat 560 °C for 0.5 2 h, followed artificial aging 160 °C, 180 200 respectively.
