“…PEO offers a facile route to grow a porous ceramic layer on metal surfaces. There remains a wide array of simpler PEO-derived surfaces that can offer antimicrobial properties [71], and PEO layers also offer benefits such as improved biocompatibility and enhanced corrosion and wear resistance [72]. Recent years have seen significant use of multi-layered approaches wherein PEO layers are combined with additional coating layers to produce more advanced functionality.…”

A detailed review of the scientific literature was undertaken to examine the most recent developments in plasma processing in the field of medicine. The first part of the review includes a detailed breakdown of the different types of coatings that can be applied onto medical devices using plasma, with a specific focus on antimicrobial surfaces. The developments in plasma-deposited biocompatibles, drug delivery and adhesive coatings in 2023 are described, and specific applications in additive manufacturing are highlighted. The use of plasma and plasma-activated liquids as standalone therapeutics continues to evolve, and pertinent advances in this field are described. In addition, the combination of plasma medicine with conventional pharmaceutical interventions is reviewed, and key emerging trends are highlighted, including the use of plasma to enhance drug delivery directly into tissue. The potential synergies between plasma medicine and chemotherapeutics for oncology and infection treatment are a growing area, and recent advancements are noted. Finally, the use of plasma to control excess antibiotics and to intentionally degrade such materials in waste streams is described.

“…Plasma electrolytic oxidation (PEO) can produce oxide ceramic-like coatings on metal substrates Lubricants 2024, 12, 105 2 of 12 submerged in electrolytes to obtain coatings with high hardness and excellent corrosion and abrasion resistance. The surface is rough with a two-layer structure and defects, and normally, further treatment, like laser processing, is needed [17]. As an environmentally friendly and low-cost technique, ceramic conversion treatment (CCT) aims to improve the tribological performance of titanium alloys by obtaining a thin and compact oxide layer backed by an oxygen diffusion zone [18].…”

Ceramic conversion treatment (CCT) is an effective way to modify the surface of titanium alloys. However, this process normally needs more than a 100-h treatment at 600–700 °C to form a hard and wear-resistant titanium oxide layer. In this paper, we pre-deposited a thin gold layer on the surface of Ti-6Al-2Sn-4Zr-2Mo (Ti6242) samples before CCT to investigate if Au can speed up the treatment. Treatments at 640/670/700 °C were carried out for 10 or 120 h. After CCT, the surface roughness, surface morphology, microstructure, elemental composition, and phase constituents were characterized. Surface hardness and the nano-hardness depth distribution were measured. Finally, reciprocating sliding tribological tests were carried out to study the friction and wear of the surface layers. Thin gold layers accelerated the CCT significantly with a much thicker oxide layer. The friction of the untreated Ti6242 alloy against the WC ball was unsteady and high, but it was much lower and stable for the CCTed samples pre-deposited with Au because of the formation of titanium oxides and lubrication effect of the gold particles. The wear resistance of the CCTed Ti6242 alloy samples with gold was reinforced significantly. By pre-depositing a thin gold layer on the surface of Ti6242, the treatment time can be cut significantly, and CCT becomes more efficient.

Nickel aluminum bronze alloy, a complex alloy containing multiple phases, has become the most common material for naval propellers due to its good corrosion resistance. Traditional cast nickel aluminum bronze shows serious corrosion behavior in harsh service environments. This article reviews progress on the corrosion behaviors and corrosion mechanism of nickel aluminum bronze in highly corrosive and complex marine environments and systematically discusses the research status of the surface modification technologies such as laser surface strengthening, mechanical shot peening, friction stir and thermal spraying, and so on. To improve the comprehensive performance of nickel aluminum bronze, this work focuses on analyzing the effect of process parameters on the corrosion resistance of nickel aluminum bronze alloy while researching propeller blade surface modification technology. Finally, the future research and development direction of nickel aluminum bronze in the fields of laser and arc additive manufacturing is prospected.
