Corrosion behaviour of reactive sputtering deposition niobium oxide based coating on the 2198-T851 aluminium alloy

NbOx overlayers protecting a NiMo alloy electrode realizing high-efficiency and durable intermittent water electrolysis

“…2d, the HER activity underwent an activation process before stabilizing. 285 cm À1 , 25,26 and vibration signals attributed to Ni-O(H) in the range of 400-500 cm À1 were also observed. Despite some fluctuations in signal strength, likely due to the bubbles generated during the test, no changes in the position of these signals were detected, suggesting that there had been no significant changes in the surface structure.…”

“…2e indicated that no MO stretching vibration signal at 900 cm −1 was detected on the NiMo/Nb surface before the reaction, indicating that the NbO x coating can effectively inhibit the transition process from Mo to MoO 4 2− . In addition, Nb–O–Nb vibration signals belonging to Nb 2 O 5 were detected at 285 cm −1 , 25,26 and vibration signals attributed to Ni–O(H) in the range of 400–500 cm −1 were also observed. Despite some fluctuations in signal strength, likely due to the bubbles generated during the test, no changes in the position of these signals were detected, suggesting that there had been no significant changes in the surface structure.…”

Laser-Induced Slippery Liquid-Infused Surfaces with Anticorrosion and Wear Resistance Properties on Aluminum Alloy Substrates

“… 10 , 11 Therefore, how to effectively reduce the surface corrosion of materials has become an important issue in the surface treatment of Al alloy materials. 12 − 14 …”

“…Aluminum (Al) alloy materials are indispensable in the industrial field due to their high strength, low density, and good processing performance, which are widely used in various fields such as electronic engineering, petrochemical engineering, and aerospace. − However, corrosion occurs when all alloy materials are exposed to the atmosphere, seawater, soil, and other media, resulting in equipment damage and huge economic losses. − Al has high electrochemical activity, and Al alloys are easy to be corroded in many application environments, especially in chloride solutions, which seriously restricts their promotion and applications in various fields. , Therefore, how to effectively reduce the surface corrosion of materials has become an important issue in the surface treatment of Al alloy materials. − …”

Development of a Low-Cost Ball-on-Flat Linear Reciprocating Apparatus: Test Validation Using Ti-6Al-4V and Ti-6Al-4V/Nb2O5 Coatings

“…Although titanium alloys exhibit good biological and corrosive properties, their usage is limited to load bearing applications due to their poor tribological characteristics [2]. Research regarding the development and application of niobium pentoxide (Nb 2 O 5 ) thin films on the titanium, aluminium and stainless-steel alloys has been performed by this research group in the last years [3][4][5][6][7][8]. Despite these excellent results, there is a lack of research that considers the effect of Nb 2 O 5 thin films on the wear properties of the Ti-6Al-4V alloy.…”
