“…It can be seen from the dynamic equation the boronizing layer thickness increases with the temperatures rising under the condition of the boronizing time remaining the same. The layer thickness changing with time is parabolic, so the boronizing time is short [10].…”

The high-vanadium alloy steel substrate surface was carried out by solid powder boronizing. The results showed that a certain thickness and compact structure of the boronizing layers could be obtained after boronizing. The thickness of the boronizing layer was about –53 μm; the thickness of the transition zone was about –36 μm, and the boronizing layer was combined with the substrate firmly. The boronizing layers consist of FeB and embed into the substrate like a spider. The alloying elements have little effect on the formation of sawtooth morphology in the boride layers. The thickness of the boronizing layers increased with the boronizing time and temperature increase, and the thickness of the boronizing layer has a parabola relationship with the processing time.

“…Treated samples can provide many advantages with the boriding process such as higher wear, oxidation, and corrosion resistance on the surface and the preservation of hardness at high temperatures [15] .Therefore, the Al2O3 that is deposited onto the surface with the coating process carried out after boriding leads to an increase in microhardness by increasing the cathodic duty cycle [16][17]. In their study on SiC particles, Luo et al reported that increasing the concentration of Al2O3 initially provides superior mechanical properties including bending strength, fracture toughness, and Vickers hardness [18].…”

The purpose of this study was to investigate the tribological properties of NiTi shape-memory alloy that was borided and coated with Al2O3 using the electrophoretic deposition (EPD) method. For the study, the sample surface was borided for 1 and 4 h at 800°C with the method of pack boriding, and the surface of the sample that was borided was coated with Al2O3 using the EPD method. The tribocorrosion properties of the untreated samples, borided samples, and borided and (duplex) Al2O3-coated samples were investigated and characterized using XRD and SEM devices. Accordingly, following the boriding treatment on the NiTi material, Al2O3 coating was successfully carried out with the EPD method. In comparison to the untreated samples, the tribocorrosion resistance of the surface-treated samples under a load of 3 N in a 3.5% NaCl solution increased. Additionally, among all samples, those that were subjected to the duplex surface treatment had the best tribocorrosion properties.

“…Cobalt-based alloys Some Co-Cr based alloys are the most preferred metallic biomaterials in orthopedic applications, especially in hip prostheses and dental applications (e.g. CoCrMo, CoCr, CoCrCu and CoCrW), for that reason, all the improvements on its mechanical performance are justified (AlMangour et al, 2020;Dobrza nski et al, 2020;Lu, 2017;Pagani et al, 2021;Uzun, 2019). A personalized femoral component of CoCrMo (CCM) with good exterior quality, mechanical property and biological corrosion resistance, obtained by the SLM process, was the achievement of the work proposed by Song (2016).…”

Purpose The purpose of this paper is to outline some key aspects such as material systems used, phenomenological and statistical process modeling, techniques applied to monitor the process and optimization approaches reported. All these need to be taken into account for the ongoing development of the SLM technique, particularly in health care applications. The outcomes from this review allow not only to summarize the main features of the process but also to collect a considerable amount of investigation effort so far achieved by the researcher community. Design/methodology/approach This paper reviews four significant areas of the selective laser melting (SLM) process of metallic systems within the scope of medical devices as follows: established and novel materials used, process modeling, process tracking and quality evaluation, and finally, the attempts for optimizing some process features such as surface roughness, porosity and mechanical properties. All the consulted literature has been highly detailed and discussed to understand the current and existing research gaps. Findings With this review, there is a prevailing need for further investigation on copper alloys, particularly when conformal cooling, antibacterial and antiviral properties are sought after. Moreover, artificial intelligence techniques for modeling and optimizing the SLM process parameters are still at a poor application level in this field. Furthermore, plenty of research work needs to be done to improve the existent online monitoring techniques. Research limitations/implications This review is limited only to the materials, models, monitoring methods, and optimization approaches reported on the SLM process for metallic systems, particularly those found in the health care arena. Practical implications SLM is a widely used metal additive manufacturing process due to the possibility of elaborating complex and customized tridimensional parts or components. It is corroborated that SLM produces minimal amounts of waste and enables optimal designs that allow considerable environmental advantages and promotes sustainability. Social implications The key perspectives about the applications of novel materials in the field of medicine are proposed. Originality/value The investigations about SLM contain an increasing amount of knowledge, motivated by the growing interest of the scientific community in this relatively young manufacturing process. This study can be seen as a compilation of relevant researches and findings in the field of the metal printing process.
