Infraestructura para el desarrollo que queremos 2026-2030

Elaborado por el Consejo de Políticas de Infraestructura (CPI), este documento constituye una hoja de ruta estratégica para orientar la inversión y la gestión de infraestructura en Chile. Presenta propuestas organizadas en siete ejes estratégicos, sin centrarse en proyectos específicos, sino en influir en las decisiones de política pública para promover una infraestructura que conecte territorios, genere oportunidades y eleve la calidad de vida de la población.

Effect of hBN on Corrosion and Wear Performances of DC Electrodeposited NiW and NiW?SiC on Brass Substrates

Mina Dadvand and Oumarou Savadogo    

Resumen

Crack-free and uniform nickel?tungsten (NiW) coatings and their composite coatings filled with ceramic particles such as silicon carbide (SiC) and hexagonal-boron nitride (hBN) were deposited on brass substrates by applying direct current (DC) waveforms. Among all coatings, NiW?SiC?hBN coatings displayed the noblest corrosion potential (-0.49 V) and lowest current density (4.36 × 10-6 A·cm-2). It also seems that addition of hBN and SiC ceramic particles to NiW matrix remarkably improved the wear performance of the NiW coatings. However, NiW?hBN exhibited the lowest wear volume (48.84 × 103 µm3) and the friction coefficient of 0.1 due to ultra?low friction coefficient of hBN particles.
