“…11(b)). This microstructure makes AMed parts have double the hardness compared to wrought steel [132], reducing both abrasive wear and adhesive wear. In the case when AMed stainless steel has a similar hardness to wrought stainless steel, its microstructure also makes it more wear-resistant [135].…”

Products made from additive manufacturing processes have attracted great attention in engineering, health care, and society at large. However, there is little knowledge about the failure of additively manufactured alloys, in particular, corrosion and wear seen in most engineering applications. The haphazard and inefficient usage of such alloys raised concerns about safety, compatibility, reliability, cost, and consumer satisfaction. To address those concerns, we studied the mechanisms of the most common failure modes, corrosion and wear, of alloys fabricated through additive manufacturing based on published literature. It was found that the processing conditions have profound influence on microstructure and thus corrosion and wear resistance of alloys. Because of the layered structure, the initiation and growth of both corrosion and wear exhibited anisotropic behavior. The insights from this review could be used as a reference of the state-of-the art and to help in the development of future additively manufactured alloys with improved corrosion and wear properties.

“…We selected laser power, scan speed and hatch space, which play a role in energy density and temperature. Also, heat treatment was selected because this process is essential in improving mechanical properties [16,17]. We also selected a laser scanning pattern angle to analyse the effect of the layering angle on the roughness.…”

When reporting surface quality, the roughest surface is a reference for the measurements. In LPBF due to recoil pressure and scan movement, asymmetric surface is shaped, and surface roughness has different values in different measurement orientations. In this research, the influence of the laser powder bed fusion (LPBF) process parameters on surface tension and roughness of Ti-6AI-4 V parts in three orientations are investigated. To improve the mechanical properties, heat treatment was carried out and added to the designed matrix to generate a comprehensive data set. Taguchi design of experiment was employed to print 25 samples with five process parameters and post-processing. The effect and interaction of the parameters on the formation of surface profile comprising tension, morphology and roughness in various directions have been analysed. The main contribution of this paper is developing a model to approximate the melting pool temperature and surface tension based on the process parameters. Other contributions are an analysis of process parameters to determine the formation and variation of surface tension and roughness and explain the governing mechanisms through rheological phenomena. Results showed that the main driving factors in the variation of surface tension and formation of the surface profile are thermophysical properties of the feedstock, rheology and the temperature of the melting pool. Also, the results showed that while the value of surface tension is the same for each test case, morphology and the value of roughness are different when analysing the surface in perpendicular, parallel and angled directions to laser movement.

“…The microstructure and the mechanical properties are both different between the parts formed by WAAM and LMD [3][4]. Take 316L stainless steel as an example, which is widely used in petroleum, petrochemical, aerospace, nuclear energy, and other industries due to its strong corrosion resistance [5][6], several researches have been carried out about its additive forming properties by different processes.…”

In order to realize both high-efficient forming with the wire arc additive manufacturing (WAAM) and precise forming with the laser metal deposition (LMD) for some complex-structure and high-precision parts, a hybrid metal additive manufacturing method is proposed. The part is decomposed into sub volumes, then the sub volumes with relatively simple-structure features are formed through WAAM as a substrate, and the other sub volumes with more complex-structure or small-sized features are formed through LMD on the former substrate. However, the mechanical properties of the bonding interface would be reduced, if the later sub volumes are directly deposited by LMD on the rough WAAM substrate surface. In order to avoid unnecessary machining process between WAAM and LMD for high efficiency, and ensure the mechanical properties of WAAM-LMD bonding interface the laser remelting method is applied for improving the profile of WAAM substrate surface. The simulation model of heat transfer and fluid flow in the laser remelting process is established, the influence of the laser power and the scanning speed on the surface-profile improvement is researched by simulation and verified by experiments, Based on that the remelting process parameters are optimized. Furthermore, based on the WAAM formed substrate, the LMD formed volumes are deposited directly, after surface milling and after laser remelting, respectively. Then the microstructure and the mechanical properties of the bonding interface are compared among the three process methods, the feasibility of the laser remelting method for improving the bonding interface performance is verified.
