This paper will detail the environmental cracking test program and results when Alloy UNS S42028 (For applications such as high collapse liners sections in high pressure high temperature (HPHT) reservoirs) was exposed to medium density bromide based clear brine fluids at a temperature of 150oC (302oF).
Resistance of S30400 and S31600 SSs to chloride-induced crevice corrosion was assessed in a wide range of temperatures and chloride concentrations. Repassivation potential of S30400 SS decreased with increasing chloride & temperatures from 0 to 60ºC, and it a constant value in the range from 60 to 90ºC regardless of chloride.
Self-healing coatings for corrosion protection refer to those with the ability to sense the corrosive environment and to release preloaded inhibitors from the coating matrix by a controlled mode. In this work, SiO2 nanoparticle based polyelectrolyte nanocontainers were fabricated by the LbL method to store corrosion inhibitor BTA.
