<p>Laser cladding of Fe-based coatings on H13 steel is a promising strategy to mitigate the severe degradation caused by high-temperature wear and corrosive environments during die-casting service. Although processing parameter optimization has been extensively reported, the correlation among microstructure evolution, high-temperature tribological behavior, and corrosion resistance requires further systematic investigation. Herein, this study investigates the microstructure, high-temperature wear mechanism, and corrosion evolution of Fe-based coatings fabricated on H13 steel. Through parameter optimization, a defect-free coating with a refined microstructure was obtained. High-temperature friction tests suggested the formation of an oxide-rich protective tribolayer on the worn surface of the coating, which was associated with a significantly reduced wear rate compared with the substrate. Moreover, electrochemical tests together with neutral salt spray (NSS) tests demonstrated that the coating exhibits superior corrosion resistance, showing a lower corrosion tendency, higher passive-film stability, and a stable long-term corrosion rate of 0.1&#xa0;g/m²&#xa0;h. The combined electrochemical and morphological evidence indicated that the formation of a dense Cr-rich passive film with good stability and an inferred re-passivation tendency effectively inhibits the intrusion of Cl-. This work provides a comprehensive theoretical basis for extending the service life of die-casting components through surface strengthening.</p>
