“…It has also been found that mechanically produced metal powders can be a cost-effective alternative to conventional gasatomised powder materials [134]. With regard to the development of a circular economy, approaches that use powder from recycling processes are also important [12,135].…”

In recent years, metal additive manufacturing developed intensively and became a relevant technology in industrial production of highly complex and function integrated parts. However, almost all additively manufactured parts must be post-processed in order to fulfil geometric tolerances, surface quality demands and the desired functional properties. Thus, additive manufacturing actually means the implementation of additive-subtractive process chains. Starting with the most relevant additive processes (powder-based PBF-LB, LMD-p and wire-based WAAM and LMD-w/WLAM), considering intermediate process steps (heat treatment and shot peening) and ending up with post-processing material removal processes (with defined and undefined cutting edges), this paper gives an overview of recent research findings with respect to a comprehensive scientific investigation of influences and interactions within the additive-subtractive process chain. This includes both the macroscopic geometric scale and the microscopic scale of the material structure. Finally, conclusions and future perspectives are derived and discussed.

The aeronautical manufacturing sector is currently involved in the 4th industrial revolution, namely Industry 4.0, improving manufacturing processes with the support of ICT. One of the objectives of this revolution is to be able to predict manufacturing defects that can have economic and operational impacts.In this work, we present a software platform that monitors and detects outliers in an industrial manufacturing process, close to real time, using scalable software tools. Our platform collects data from a machine, processes it and plots visualizations in a dashboard with the results. The IQR method is used to detect outliers in the manufacturing process.We validate our platform by monitoring an Ibarmia THR 16, a versatile machining centre, located at the Aeronautics Advanced Manufacturing Centre in Zamudio, Spain. We conduct a performance evaluation of our platform in several ways and present the results, highlighting bottlenecks such as the limits of the OPC-UA industrial communication protocol.

“…A fine microstructure was found to be positively correlated with microhardness. In the work of [ 24 ], it was established a surface roughness increasing because of the particle size increasing in reused powders during the printing process. Directly, the flowability of powder is also affected upon depositing a new layer.…”

Mechanical and Chemical Characterisation of TiN and AlTiSiN Coatings on a LPBF Processed IN718 Substrate

et al. 2021

Wear-resistant coatings development is progressively increasing steeply due to their advantages when applied to mechanical components subjected to abrasive and destructive environments. Titanium nitride (TiN) coating is typically used to enlarge tools and components’ service life and improve their surface quality. On the other hand, AlTiSiN coating intends to be applied to more aggressive environments such as spatial satellites components exposed to solar radiation, extremely high temperatures, and random particles impact. In this work, specimens of Inconel 718 (IN718) were fabricated via laser powder bed fusion (LPBF), and physical vapour deposition (PVD)-deposited with TiN and AlTiSiN as coatings to mechanically and chemically characterise their surface. In this respect, microhardness testing and chemical analysis via glow discharge optical emission spectroscopy (GDOES) were performed. Later, roughness and wear behaviour analyses were carried out to evaluate the mechanical performance of both coatings and their surface and morphological features. The experimental observations allowed the analysis of both studied coatings by comparing them with the substrate processed via LPBF.
