“…The researchers observed that the surface layer of the nitrided stainless steel exhibited significantly enhanced cavitation resistance compared to the reference samples. In their study, Mitelea et al [94] employed gas nitriding technology to fabricate coatings on the surface of aluminum alloys. This approach demonstrated a significant enhancement in the cavitation resistance of the alloys.…”

The performance of an entire ship is increasingly impacted by propellers, which are the essential components of a ship’s propulsion system that have growing significance in a variety of aspects. Consequently, it has been a hot research topic and a challenge to develop high-performance antifouling and anti-cavitation coatings due to the issue of marine biofouling and cavitation faced by propellers in high-intensity service. While there is an overwhelming number of publications on antifouling and anti-cavitation coatings, a limited number of papers focus on integrated protective coatings on propellers. In this paper, we evaluated the development of antifouling and anti-cavitation coatings for ship propellers in the marine environment as well as their current status of research. These coatings include self-polishing antifouling coatings, fouling-releasing antifouling coatings, and biomimetic antifouling coatings for static seawater anti-biofouling, as well as anti-cavitation organic coatings and anti-cavitation inorganic coatings for dynamic seawater anti-cavitation. This review also focuses both on the domestic and international research progress status of integrated antifouling and anti-cavitation coatings for propellers. It also provides research directions for the future development of integrated antifouling and anti-cavitation coatings on propellers.

“…[18][19][20] However, titanium alloys, and particularly pure titanium, do not possess high resistance to erosive wear because of the relatively low surface hardness. [1][2][3][4][5][6] Therefore, various methods to modify the surface of the titanium alloys are used in industry, and also new methods and techniques are being developed. [1][2][3][4][5][6]21 Among the many methods of surface modification of titanium alloys, one of the most efficient is laser gas nitriding (LGN).…”

A prototype experimental stand equipped with a novel high-power direct diode laser (HPDDL), characterized by unique properties of the laser beam, was applied for producing titanium-matrix composite (TMC) surface layers during the laser gas nitriding (LGN) of the titanium alloy Ti6Al4V in the liquid state. The erosion wear characteristic of the substrate and nitrided surface layers was investigated. It was found that the erosion wear resistance of the composite surface layers is significantly higher than the substrate of titanium alloy Ti6Al4V. The erosion wear resistance depends on the angle of incidence. Reducing the angle of incidence decreases the weight loss of the composite surface layers and simultaneously increases the weight loss of the Ti6Al4V. It was found that the weight loss of the composite surface layer with the highest resistance is over six times lower compared to the Ti6Al4V, at an incident angle of 15°. Keywords: laser nitriding, titanium alloy, diode laser, erosion wear, composite Prototipno eksperimentalno stojalo opremljeno z novim diodnim laserjem velike mo~i (HPDDL), zna~ilnem po edinstvenih lastnostih laserskega`arka, je bilo uporabljeno za izdelavo povr{inske plasti kompozita na osnovi titana (TMC), med plinskim nitriranjem z laserjem (LGN) titanove zlitine Ti6Al44V, v staljenem stanju. Preiskovane so bile zna~ilnosti erozijske obrabe podlage in nitrirane povr{ine. Ugotovljeno je bilo, da je odpornost na erozijsko obrabo kompozitne povr{inske plasti ob~utno ve~ja v primerjavi s podlago iz titanove zlitine Ti6Al4V. Odpornost na erozijsko obrabo je odvisna od vpadnega kota. Zmanj{anje vpadnega kota zmanj{uje izgubo te`e povr{inke kompozitne plasti in hkrati pove~a izgubo te`e Ti6Al4V. Ugotovljeno je, da je izguba te`e kompozitne povr{inske plasti, z najve~jo odpornostjo, pri vpadnem kotu 15°, ve~kot {est krat manj{a v primerjavi z Ti6Al4V.
