Special Issue Information

Dear Colleagues,

Metal additive manufacturing is a rapidly expanding area owing to its flexibility to fabricate components of intricate geometries with customized features for a wide range of applications. However, these parts generally exhibit inadequate and poor surface quality in the as-built configuration. Surface modification techniques including cold spraying, friction stir processing, and laser or electron beam-based deposition processes are widely used to further improve the surface properties of metallic materials, such as corrosion resistance, wear resistance, microhardness, oxidation resistance, etc. This Special Issue focuses on various additive manufacturing techniques, such as laser powder bed fusion (LPBF), direct energy deposition (DED), cold spraying (CS), friction stir processing (FSP), etc., and various surface modification techniques are also included in this Special Issue, like friction stir processing, micro-arc oxidation, laser remelting, laser shot peening, etc. The materials studied can be pure metals, alloys, and composites. The properties for surface modification include but are not limited to corrosion resistance, wear resistance, oxidation resistance, cavitation resistance, antibacterial properties, and magnetic properties.

This study designed laser engraving and resin pre-coating (RPC) treatments on an aluminum alloy (AA) surface to construct through-the-thickness “epoxy pins” for improving the bonding strength with carbon fiber reinforced polymer (CFRP). A laser engraving treatment was used to create a pitted structure on the AA surface; higher wettability was acquired and greater vertical spaces were formed to impregnate epoxy resin, resulting in stronger mechanical interlocking. The RPC technique was further used to guide high-viscosity epoxy resin into pits to form the epoxy coatings and to minimize defects between the resin and the substrate. The bonding strength of the specimen treated with both laser engraving with a unit dimension of 0.3 mm and RPC increased up to 227.1% in comparison with that of the base. The failure modes of the hybrid composites changed from the debonding failure of the AA surface to the delamination-dominated failure of the laminated CFRP composites. It was confirmed that laser engraving is a feasible and effective method when combined with RPC for treating AAs to improve the bonding strength of AA-CFRP composites, which provides a reference for preparing high-performance hybrid composites with metals.
