“…The surface of these composites exhibits higher hardness and wear resistance, while the bulk material retains its toughness [13]. Various methods, such as laser-assisted processes, centrifugal casting, and plasma spraying, have been developed to fabricate surface MMCs [13][14][15][16][17] and involve the transformation of material from a solid to liquid or vapor state during processing.…”

Surface metal matrix composites offer an excellent solution for applications where surface properties play a crucial role in components’ performance and durability, such as greater corrosion resistance, better wear resistance, and high formability. Solid-state processing techniques, such as friction surfacing and friction stir welding/processing, offer several advantages over conventional liquid-phase processing methods. This research investigated the feasibility of producing surface composites of aluminium-based dissimilar alloys reinforced with functional microparticles through experimental validation, determined the process parameters that resulted in a more homogeneous distribution of the particles in the surface composites, and enhanced the understanding of Upward Friction Stir Processing (UFSP) technology. The production of aluminium-based dissimilar alloys (AA 7075-T651 and AA 6082-T651) surface composites reinforced with SiC particles was studied, and it was concluded that the macrography and micrography analyses, scanning electron microscopy (SEM) analysis, microhardness measurements, and eddy currents technique reveal an extensive and homogeneous incorporation of SiC particles. In the stirred zone, a decrease of approximately 20 HV 0.5 in hardness was observed compared to the base material. This reduction is attributed to the weakening effect caused by low-temperature annealing during UFSP, which reduces the strengthening effect of the T651 heat treatment. Additionally, the presence of particles did not affect the surface composite hardness in the stirred zone. Furthermore, despite the presence of significant internal defects, SEM analyses revealed evidence of the lower alloy merging with the upper zone, indicating that the lower plate had a role beyond being merely sacrificial. Therefore, the production of bimetallic composites through UFSP may offer advantages over composites produced from a monometallic matrix. The results of the eddy currents testing and microhardness measurements support this finding and are consistent with the SEM/EDS analyses.

Blade is the critical and extensively used component of aero-engine, which machining quality directly affects engine performance. Due to its flexibility, laser solid forming (LSF) from powders is widely used to synthesis novel materials, build three-dimensional parts, repair damage part and form surface coating in advanced manufacturing. To repair damaged parts or form surface coating, especially for aero-engine free-form surface blade, process of numerical control or robotic LSF is applied in industry. Nevertheless, on account of the complex geometry of the free-form surface, it's quite a challenge to generate proper laser beam paths according to the process requirements of LSF. To address this problem, a path generation method based on the differential geometry is presented. The generated paths can ensure the overlap requirements between deposited tracks as well as paths shifts between adjacent layers. The proposed method has been applied to two examples to verify their validity, and there exists a great potential for the applications in aeroengine manufacturing industry, especially in the LSF repair or surface coating of free-form surface blade.

“…In recent times, laser based techniques such as laser cladding and laser deposition have made headway in the area of surface modification. These techniques can quickly melt metal surface and then the metal rapidly solidifies, which helps to improve the surface properties of the materials 3. Farayibi et al 4 have investigated cladding of concurrently fed Ti–6Al–4V wire and WC powder for production of tracks, area cladding and a 3D structure using a range of powder feed rates, examined geometric characteristic variation, microstructural evolution.…”

From the last decade the electrical discharge machining (EDM) has been investigated as the process for surface modification besides machining. This paper describes the influence of W-Cu powder metallurgical electrodes at various parametric conditions on the surface of mild steel through electric discharge coating (EDC) process for its modification. Taguchi design of experiments is used to investigate the parameters which favour material transfer rate (MTR) with acceptable surface finish. Analysis of variance (ANOVA) and overall evaluation criteria (OEC) has been performed to the output parameters such as MTR and surface roughness R a to find the percentage contribution of different controlling parameters for uniform deposition. The highest MTR of 195 mg min 21 and the surface roughness of 2?6 mm have been successfully achieved.
