“…Secondly, the longer the DCT duration, the smaller the COF value. This result was consistent with the microhardness tests [22,23,24]. Eventually, the lowest COF of all the samples was the 24 HCT sample, where the COF was reduced by about 30% compared with the 0 HCT sample.…”

The effect of deep cryogenic treatment on microstructure and wear resistance of LC3530 Fe-based powder laser cladding coating was investigated in this paper. The cladding coating was subjected to deep cryogenic treatment for the different holding times of 3, 6, 9, 12, and 24 h, followed by tempering at room temperature. Microstructure of the cladding coating was observed by optical microscope (OM) and the microhardness was measured by the Vickers-hardness tester. The wear was tested by ball and flat surface grinding testing conducted on the material surface comprehensive performance tester. The wear scars were analyzed using a non-contact optical surface profiler and scanning electron microscope (SEM). The results showed the grain size of cladding coating after 12 h of deep cryogenic treatment was significantly reduced by 36.50% compared to the non-cryogenically treated cladding coating, and the microhardness value increased by approximately 34%. According to the wear coefficient calculated by the Archard model, the wear resistance improved about five times and the wear mechanism was micro-ploughing. The deep cryogenic treatment could enhance the wear resistance of the cladding coating by forming a wear resistant alloy compound and higher surface microhardness.

“…The conducted studies have shown that efficient operational performance as the target yields the best results as the tool, die, or mold is designed for and made by L-PBF [1,11,25,[30][31][32][33][34][35][36]. This review shows that it is possible to improve this operational performance by adding LMPp (DED-p, LC) for surface functionalization [41][42][43][44][45][46][47][48][49][50][51] and tool, die, or mold remanufacture [52,[56][57][58][59][60][61][62][63][64]. Tool remanufacture can, in other words, be added as a factor that influences the tool life and thereby the operational efficiency during the tool life cycle.…”

“…DED-p (or LMD-p or LC), even called Blown Powder Technology [40], can be used to improve a tool's operational performance. In several investigations, this technology is used to coat the tool (die or mold made conventionally in wrought steel) with: a cobalt (Co) based Stellite alloy (Co, 20-30 wt% chromium (Cr), 4-18 wt% tungsten (W) or molybdenum (Mo), and 0.25-3 wt% carbon (C)) for resistance to high temperature, oxidation, wear, and corrosion, and for high hardness [41,42]. nickel (Ni) based hard facing alloys (NiSiB, NiCrSiB, Inconel 625 (NiCrSiBFeC) etc.)…”

This paper explores the possibilities to use laser-based additive processes to make, surface treat and repair/remanufacture tools, dies and molds for cold working, hot working, and injection molding. The failures encountered in these applications are described. The materials used conventionally and in the laser additive processes are accounted for. The properties of the tools, dies and molds made by Laser-based Powder Bed Fusion (L-PBF) are as good as and in some cases better than the properties of those made in wrought materials. Shorter cycle time, reduced friction, smaller abrasive wear, and longer life cycle are some of the benefits of L‑PBF and Directed Energy Deposition with powder (DED-p) (or Laser Metal Deposition with powder, LMD‑p, or Laser Cladding, LC). L‑PBF leads to higher toolmaking costs and shorter toolmaking lead time. Based on a review of conducted investigations, this paper shows that it is possible to design and make tools, dies and molds for and by L‑PBF, surface functionalize them by DED-p (LMD‑p, LC), and repair/remanufacture them by DED-p (LMD‑p, LC). With efficient operational performance as the target for the whole tool life cycle, this combination of L‑PBF and DED-p (LMD‑p, LC) has the greatest potential for hot working and injection molding tools and the smallest for cold working tools (due to the current high L‑PBF and DED-p (LMD‑p, LC) costs).

“…Stellite TM alloys are among the so-called superalloys. As mentioned, they are Co-based alloys that contain a high amount of chromium (20%-30% (mass fraction)), Tungsten (4%-18% (mass fraction)), Molybdenum and carbon (0.25%-3% (mass fraction)) [139]. Stellite TM alloys have also been chosen as tool materials for machining stainless steel owing to their weldability, properties, and powder availability.…”

Additive manufacturing (AM) technologies are currently employed for the manufacturing of completely functional parts and have gained the attention of high-technology industries such as the aerospace, automotive, and biomedical fields. This is mainly due to their advantages in terms of low material waste and high productivity, particularly owing to the flexibility in the geometries that can be generated. In the tooling industry, specifically the manufacturing of dies and molds, AM technologies enable the generation of complex shapes, internal cooling channels, the repair of damaged dies and molds, and an improved performance of dies and molds employing multiple AM materials. In the present paper, a review of AM processes and materials applied in the tooling industry for the generation of dies and molds is addressed. AM technologies used for tooling applications and the characteristics of the materials employed in this industry are first presented. In addition, the most relevant state-of-the-art approaches are analyzed with respect to the process parameters and microstructural and mechanical properties in the processing of high-performance tooling materials used in AM processes. Concretely, studies on the AM of ferrous (maraging steels and H13 steel alloy) and non-ferrous (stellite alloys and WC alloys) tooling alloys are also analyzed.
