A primary study of the effect of hydrostatic pressure on stress corrosion cracking of Ti-6Al-4V alloy in 3.5% NaCl solution

Stress corrosion cracking of carbon steels on CO2 /H2 O systems

“…A lack of information regarding the effect of higher hydrostatic pressure on corrosion cracking could be found in the literature. Hydrostatic pressure (HP) can lead to a sudden increase in mechanical driving force on a component containing a microcrack and inducing a restart of propagation after a crack tip blunting in case of crack dormancy or a microcrack previously nucleated at corrosion pits [55].…”

An amorphous SiAlN barrier coating against NaCl attack in humid air at elevated temperature

“…Ti alloys are widely applied in gas turbine aeroengines and hybrid-electric airplanes due to their low density and high specific strength [1][2][3][4][5]. In fuel-efficient innovations for aeroengines or hybrid-electric airplanes, Ti alloys have found applications in components exposed to relatively high temperature and chemically aggressive demanding environments, e.g.…”

“…as a fan blade (Ti6Al4V), compressor (Ti6242 or Timetal 834), or turbine blade (low pressure, TiAl alloys) [6][7][8]. However, Ti alloys have inadequate oxidation resistance at high temperatures, which restricts their applications for fuel-efficient innovations [4,9]. Therefore, the application of Ti alloys relies on coatings technologies allowing for improved oxidation resistance of the alloys in such harsh environments [4].…”

Deep‐sea corrosion rusticles from iron‐hulled shipwrecks

“…[11,12] Hydrostatic pressure is known to enhance localised corrosion and pit formation on several metals and alloys, and to increase water absorption into the coatings. [13][14][15][16][17] Both phenomena are caused by the thinning effect hydrostatic pressure and ionic strength have on the hydration layer of ions, which reduces the radii of the hydrated ions. [18,19] A reduction in the ionic radii facilitates the migration of ions through a coating and reduces the charge transfer resistance at the interface between the metal and the seawater (electrolyte) by allowing the solvated ions to come closer to the metal and interact/ react with it.…”
