The oxygen-doped titanium alloys fabricated by PM have a unique combination of high strength and good plasticity. Another advantage is that the oxygen is much cheaper than typical alloying elements such as vanadium or molybdenum. The work presents the effect of the introduction of TiO<sub>2</sub> in PM titanium on its microstructure and corrosion resistance in 10 wt.% solution of hydrochloric acid. Three various blends of pre-mixed Ti–<em>x</em>TiO<sub>2</sub> (<em>x</em> = 0, 0.2 wt.% and 0.4 wt.%) were used to manufacture titanium specimens by the conventional PM (uniaxial pressing and subsequent vacuum sintering). It was shown that an increase in the content of TiO<sub>2</sub> powder in the raw powder mixture enhanced the residual porosity in titanium specimens. The dissolved oxygen atoms resulted in the lattice constant change, thereby increasing the microhardness and residual microstrain in titanium. According to the electrochemical impedance spectroscopy, polarization and immersion tests, it was determined that oxygen doping of titanium specimens decreases their corrosion resistance. The enhancement of the residual microstrain and porosity in titanium specimens due to the introduction of TiO<sub>2</sub> in the powder mixture is the main reason that worsens the corrosion performance.</div></div>","PeriodicalId":100337,"journal":{"name":"Corrosion Communications","volume":"19 ","pages":"Pages 129-137"},"PeriodicalIF":9.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Superhydrophobic surfaces possess excellent passive anti-icing properties owing to their outstanding water repellent ability.

In this paper, a simple laser etching method was used to prepare superhydrophobic anti-icing surface on DH36 steel, especially for polar ships. Contact angle of the prepared superhydrophobic surface was about 161°, and sliding angle was only 3° Meanwhile, icing time was 13.4 times longer than that of untreated steel surface. In addtion, such superhydrophobicity remains after 10 icing and de-icing cycles. Adequate surface roughness and adsorption of low surface energy substances in vacuum drying furnaces provide excellent hydrophobicity on this surface.
