“…The results indicated that strict precautionary measures (e.g., modification of microstructure, scanning strategy, or barrier layer formation) must be taken to avoid the more severe corrosion damage to AM Ti–6Al–4V alloys that occurs in neutral or vigorously corrosive media. Morris et al [ 20 ] studied the relation between corrosion and porosity associated with the improved biocompatibility and osseointegration of 3D-printed porous Ti in biomedical applications. They found that corrosion increases as porosity increases, maintaining the need for the existence of optimum porosity for biocompatibility.…”

This study proposes a new method, electrochemical critical localized corrosion potential (E-CLCP), in order to evaluate localized corrosion resistance of biomedical additive manufacturing (AM) titanium (Ti) alloys. The procedures for determining E-CLCP are completely different from that of the electrochemical critically localized corrosion temperature (E-CLCT) method (ISO 22910:2020). However, its application should be limited to pH and temperature of the human body because of the temperature scan. E-CLCP displays the localized corrosion resistance of AM Ti alloys based on the human body’s repassivation kinetics, whereas E-CLCT displays the localized corrosion resistance of the alloys based on passive film breakdown in much harsher corrosive environments.

“…They indicated that the electrochemical response of porous AM-produced Ti samples experienced crevice corrosion and intergranular corrosion mechanisms. They also concluded that the AM-manufactured Ti samples with larger porosity showed increased corrosion values; the optimum range of porosity was revealed to be between 40% and 60% [111]. In another study, Sharp et al [112] investigated the corrosion performance of AM-produced Ti6Al4V gyroid lattices with varied porosity values (60-80%).…”

Today, parts made by additive manufacturing (AM) methods have found many applications in the medical industry, the main reasons for which are the ability to custom design and manufacture complex structures, their short production cycle, their ease of utilization, and on-site fabrication, leading to the fabrication of next-generation intricate patient-specific biomedical implants. These parts should fulfill numerous requirements, such as having acceptable mechanical strength, biocompatibility, satisfactory surface characteristics, and excellent corrosion and wear performance. It was known that AM techniques may lead to some uncertainties influencing part properties and causing significant evaluation conflicts in corrosion outcomes. Meanwhile, the corrosion and wear behavior of additively manufactured materials are not comprehensively discussed. In this regard, the present work is a review of the state-of-the-art knowledge dedicated to reviewing the actual scientific knowledge about the corrosion and wear response of additively manufactured biomedical components, elucidating the relevant mechanism and influential factors to enhance the performance of AM-manufactured implants specifically for the physiological human body fluids. Furthermore, there is a focus on the use of reinforced composites, surface engineering, and a preparation stage that can considerably affect the tribocorrosion behavior of AM-produced parts. The improvement of tribocorrosion performance can have a key role in the production of advanced AM implants and the present study can pave the way toward facile production of high-throughput AM biomedical parts that have very high resistance to corrosion and wear.

“…Besides, larger pores, which promote the growth of the bone, are more subjected to corrosion as demonstrated by Morris et al. 175 Hence a trade-off between these two aspects drives to the optimal configuration.…”
