In recent years, additive manufacturing technologies have become increasingly widespread with the most intensive development being direct metal deposition (DMD), alloys, and ceramic materials on a metal substrate. This study shows the possibilities of the effective formation of coatings, based on heterogeneous metal alloys (Ni-based alloy and Fe-Al bronze) deposited onto 1045 structural steel. Changes in the microhardness, the microstructure, and the tribological properties of the composite coating, depending on the laser spot speed and pitch during DMD processing, have been considered. It was revealed that if the components of the composite coating are chosen correctly, there are possible DMD conditions ensuring reliable and durable connection between them and with the substrate.

Functionally graded materials (FGMs) are specially designed composite materials that gradually change their material properties. This distinctive property of materials comes with new challenges in the design and manufacturing sector. For such challenges, the best options are material property computation and material modelling using different computational materials science (CMS) algorithms. This review paper provides enriched information on CMS with an overview of the available FGM production techniques with a detailed study of FGM use in biomedical applications based on the available literature over the past couple of decades.

“…Diffusion of Cu in Al during heat treatment enhances its hardness, strength, machinability, creep, wear, and fatigue resistance. 26 The studies 15,[27][28][29] reported on Al-Cu FGM presented only the mechanical properties such as microstructure, density, hardness, and strength. Few other works examined the acoustic impedance, residual stresses, and corrosion wear.…”

A five-layered aluminum–copper metal functionally graded material was developed through powder metallurgy process. The sample comprises different weight percentages of copper and aluminum that vary from 0 wt% to 100 wt % along the thickness direction. Erosion wear was performed on air jet erosion testing apparatus at a constant impact angle of 90o and impact velocity of 151 m/s. It was observed that erosion wear decreases when there is an increase in copper content. Layer 1 comprising 100 wt% of copper has shown 76.92% lower wear compared to layer 5 (100 wt% of aluminum). Besides, erosion resistance was enhanced at graded layers due to the formation of Al2Cu phase during sintering. Abrasive wear of metal functionally graded material was evaluated on the pin-on-disc test apparatus. Experiments were conducted at different loading conditions on various abrasive surfaces (P120, P800, and P2000). Irrespective of abrasive surface, the specific wear rate of aluminum–copper metal functionally graded material sample increased with an increase in load from 5N to 15N. At 5N, abrasive wear of metal functionally graded material on P2000 grit surface was 87.7% and 27.19% lower compared to P120 and P800, respectively. Eroded and worn-out surfaces were examined microscopically to understand the wear mechanisms and are discussed in detail.
