“…While water-quenching improved the tribological and wear behavior under dry conditions, this was worsened due to cooling in the furnace. For the application in tooling, Franke-Jurisch et al [151] investigated the wear behavior of Fe-Cr-V alloy in jet-wear and impact tests as well as in field tests with AM tools. In the jet-wear tests, the additively manufactured specimens achieved a higher wear resistance than the reference specimens.…”

Innovative additive manufacturing processes for resilient and sustainable production will become even more important in the upcoming years. Due to the targeted and flexible use of materials, additive manufacturing allows for conserving resources and lightweight design enabling energy-efficient systems. While additive manufacturing processes were used in the past several decades mainly for high-priced individualized components and prototypes, the focus is now increasingly shifting to near-net-shape series production and the production of spare parts, whereby surface properties and the tribological behavior of the manufactured parts is becoming more and more important. Therefore, the present review provides a comprehensive overview of research in tribology to date in the field of additively manufactured components. Basic research still remains the main focus of the analyzed 165 papers. However, due to the potential of additive manufacturing processes in the area of individualized components, a certain trend toward medical technology applications can be identified for the moment. Regarding materials, the focus of previous studies has been on metals, with stainless steel and titanium alloys being the most frequently investigated materials. On the processing side, powder bed processes are mainly used. Based on the present literature research, the expected future trends in the field of tribology of additively manufactured components can be identified. In addition to further basic research, these include, above all, aspects of process optimization, function integration, coating, and post-treatment of the surfaces.

“…Layerwise build-up enables the tool-free fabrication of complex geometries, with few geometrical restrictions [1,2]. High-vacuum conditions, in combination with high process temperatures and the ability to tailor the spatiotemporal energy input, enable the processing of a large variety of metal alloys [3][4][5][6][7][8][9] and even the local tailoring of microstructure and properties [10][11][12][13][14]. The selection of appropriate process parameters in PBF-EB is critical for the fabrication of defect-free parts with predetermined homogeneous material properties.…”

High-Throughput Numerical Investigation of Process Parameter-Melt Pool Relationships in Electron Beam Powder Bed Fusion

The reliable and repeatable fabrication of complex geometries with predetermined homogeneous properties is still a major challenge in electron beam powder bed fusion (PBF-EB). Although previous research identified a variety of process parameter–property relationships, the underlying end-to-end approach, which directly relates process parameters to material properties, omits the underlying thermal conditions. Since the local properties are governed by the local thermal conditions of the melt pool, the end-to-end approach is insufficient to transfer predetermined properties to complex geometries and different processing conditions. This work utilizes high-throughput thermal simulation for the identification of fundamental relationships between process parameters, processing conditions, and the resulting melt pool geometry in the quasi-stationary state of line-based hatching strategies in PBF-EB. Through a comprehensive study of over 25,000 parameter combinations, including beam power, velocity, line offset, preheating temperature, and beam diameter, process parameter-melt pool relationships are established, processing boundaries are identified, and guidelines for the selection of process parameters to the achieve desired properties under different processing conditions are derived.

“…Another advantage of the combined AM and HIP process route is the opportunity to use different materials for the AM fabricated capsule and the HIP densified powder. When the capsule remains on the finished part, it forms a composite component and can act as a functional layer, either corrosion- [7] or wear-resistant [8,9].…”

Abstract. Additive Manufacturing (AM) is an emerging technology with increasing importance in scientific and industrial applications. It is suitable for the manufacturing of very complex components straight from CAD data. Furthermore, it can complement powder metallurgical (PM) Hot Isostatic Pressing (HIP) when it is used to produce geometrical complex capsules, opposed to the manual fabrication by welding of sheet metal. This combined process route is highly automatable and can even be further enhanced when it is accompanied by numerical simulations in the design process of the near-net-shape capsules. Due to design optimization, there is no need to remove the capsule and it becomes an integral and functional part of the component. When the capsule is produced e.g., from wear-resistant materials, it can form a wear-resistant outer layer. This study comprises the manufacturing of net-shape and wear-resistant HIP capsules from the carbide rich cold working tool steel AISI A11 (X245VCrMo10-5-1) via Powder Bed Fusion – Electron Beam (PBF-EB). The capsules are filled with the tough Q+T steel AISI L6 (56NiCrMoV7) and densified by HIP with an integrated heat treatment. The focus is on the validation of the simulation, microstructural analysis, as well as analysis of the wear-resistance.
