Marine machinery and engine components face humid and corrosive environments. Steels or Ni-based materials with high strength and outstanding corrosion resistance are often employed in marine services for their good strength and corrosion resistance properties. High alloy strength and good corrosion resistance are difficult to achieve simultaneously. Selective laser melted (SLM) austenitic steels present a new pathway to improve strength, work hardening, and ductility. Due to SLM products’ superior strength compared to most other metal 3D printed parts, this technology is highly sought after in high-end applications. SLM can produce extremely complex geometries and reduce part counts by printing entire assemblies. SLM lowers waste and material utilisation, especially when compared to conventional manufacturing techniques. The resulting microstructure in SLM-processed alloys, is mostly composed of submicron dislocation walls. This type of microstructure may have the potential to improve corrosion resistance. SLM processing can produce a single-phased high entropy alloy samples, with not only exceptional strength-ductility combinations, but also excellent corrosion resistance in acidic environments. Rui Zhou et al. from department of Materials Science and Engineering, Hong Kong Institute for Advanced Study, City University of Hong Kong, have shown that SLM is capable of doubling the corrosion resistance of an N-doped CoCrFeNi HEA in diluted sulfuric acid, while still maintaining high mechanical performance. The sample that underwent SLM processing has an uneven microstructure with 3D dislocation cells inside each grain. The SLM-induced 3D dislocation cell structure can offer efficient diffusion pathways, allowing migration of Cr to the metal surface. This results in the formation of a thick protective Cr oxide layer that offers good corrosion resistance. Additionally, Cr segregation at cell borders creates a large number of sites for oxide nucleation and stabilises the cell structure for strong mechanical characteristics.

The Beginning
UK National Women in Engineering Day held annually on June 23rd, a movement started by the Women’s Engineering Society (WES) the forerunner to International Women in Engineering Day (INWED), and first took place in the UK in 2014. The objective behind this WES initiative was to raise the profile of women in engineering. The day gained support from UNESCO two years later, raising awareness on a global scale. Finally, in 2017, the day was celebrated on an international level for the first time. The day was first observed internationally in 2017 – a day that honours and celebrates the tenacious efforts made by female engineers.
Objectives
The main goals of the day are to raise awareness and promote female participation in the engineering field. INWED recognises importance of female engineering pioneers, who are frequently overlooked. The awareness campaigns are to equip young girls with boundless opportunities to help them carve a niche for themselves. INWED also gives a platform to conduct outreach programmes with younger generations and early career professionals. The initiative has listed 40 UK-based events, with many more occurring elsewhere, to deliver and support learning sessions.
Theme
This year will mark the 10th celebration of International Women in Engineering Day. Every year the day is attributed to different themes and INWED 2023 theme is ‘Make Safety Seen’ to highlight how female engineers have broken through barriers in creating technology for a safe future. It also serves as a platform to discuss the actions that can be taken to ensure a safe personal environment for female engineers to work in.
INWED 23 Celebrations and Awards
Various events, including webinars, podcasts, award ceremonies, and tours, were held to mark INWED 23 by businesses, organisations, and educational institutions. Several INWED 2023 events are listed on following website: https://www.inwed.org.uk/events/
A new free gallery at London’s Science Museum was opened to public on Friday 23rd June. The gallery will explore how engineers
change the world.
RWE, the UK’s electricity generator celebrated International Women in Engineering Day by hosting a tour of the largest wind farm in
Welsh waters.
CORROSION journal hosted a podcast in which Dr Jen Locke, from The Ohio State University, and Dr Erin Karasz, from Sandia National Laboratories, discussed their careers in materials science and engineering.
Women Engineers Making News
Sharon Harte of Dacrylate Paints was elected President of British Coatings Federation (BCF). Sharon taking over from Guy Williams and becomes the first female President of the BCF – or its predecessor organisations – in its 111-year history. For the 2023 British Coatings Federation (BCF) Annual Conference, more than 150 top business leaders and decision-makers from the UK’s paints, coatings and printing ink industries gathered in Derby.
Within the Transport sector, Kris Kinnear, capital delivery director at Network Rail recently commented:
“As an industry, we are keen to encourage more young women and girls to get involved in engineering opportunities and careers. Visits such as these support our platform of diversity and inclusion, and help us to promote the role and contribution female engineers play in the industry on a daily basis.

The seminar was part of a series of technical events that the GPC arranges collaboratively with international corrosion associations. The seminar was held virtually and the speaker was Prof. Gareth Hinds, the President of WCO, who focused on reviewing corrosion challenges associated with developing technologies. The event had the active participation of delegates from oil and gas companies in Qatar, university faculty members, researchers, students, and overseas corrosion professionals.
According to Hexigone, their latest test results prove that their sustainable corrosion inhibitor, Intelli-ion AX1, can reach C5 levels of corrosion protection in both waterborne and solvent borne coatings.
C1–C5 are classifications used to describe the level of corrosion resistance required for aggressive environments and applications. C5 refers to highly corrosive environments where the steel structure is exposed to high levels of humidity, saltwater spray, and other corrosive substances.
The coatings that were tested were specially formulated by a UK-based organisation that provides technical and scientific support to the global coatings industry. The REACH compliant inhibitors were added to both waterborne (WB) and solvent borne (SB) 2 pack epoxy coatings, and both primer only and top-coated systems were tested.
The panels used for testing were shot-blasted to Sa 2.5 as per C5 specification. Each primer layer had an average dry film thickness (DFT) of 120 µm, and the topcoat was applied at approx. 60 µm. After 1440 hours salt spray (SST) to ASTM B117 both the primer and full system for the WB epoxy and SB epoxy displayed no signs of blistering in the coating. To demonstrate the full performance of both systems with AX1 in, part of the paint system was removed after salt spray to view the substrate underneath. The WB epoxy system after 1440 hours shows minimum corrosion at the scribe, evidencing Intelli-ion’s excellent performance in WB systems. The SB epoxy system also meets specifications with no blistering, minimum cross-scribe corrosion, and no undercoat corrosion present on the full substrate.
Unlike zinc phosphate, which primarily provides anodic protection via precipitation, Intelli-ion offers both anodic and cathodic corrosion protection. The technology is released in a smart way and works by forming a protective nano layer on the metal surface, which provides a physical barrier to corrosion-inducing substances. The final mode of protection happens once it has donated a proton to OH- ions resulting from the cathodic oxygen reduction reaction, it forms a lone pair bonded layer over the metal surface at the cathode, blocking interfacial electron transfer.
Hexigone invites coatings manufacturers worldwide to join forces and co-create high-performance, sustainable, smart coatings.
