... material values. For investigations under compressed conditions, the compression set was determined for specimens of ACM, FKM and HNBR after exposure in heating oil B0 and B20 for 3,7,14, 28, 56 and 90 days at 40 °C according to ISO 815-1. It was found that the resistance in B20 at 40 °C was given for all...

...]. A key issue is that microturbine exhaust gas contains water vapor which could decrease the oxidation lifetime of Cr 2 O 3 -forming alloys such as S30400 or N06625 due to the formation of volatile CrO 2 (OH) 2 [8, 9]. Greater Cr depletion was reported for the S30403 steel coupon after 679 h of exposure...

The surface film structure after exposure in the actual well was composed of sulfides and oxides. This thin layer structure is consistent with laboratory results using small-scale...

... environment, typical stainless steel may easily corrode. 1 Cyclic polarization test was carried on each sample after exposure period of 0, 1, 3, 5, 7, 10, 13, and 20 days to evaluate the resistance to the localized corrosion. 2 The sweep rate was 1 mV/s. To verify the stability of Platinum reference...

... of the coating material. The tool was retrieved after three months exposure to the reservoir condition for post-laboratory analysis. The retrieved coupons were thoroughly characterized to assess the coating performance and to understand the corrosion and scaling mechanisms. XRD was used to analyze...

Other considered factors were: pH of the droplet, temperature, droplet volume, and exposure time. INTRODUCTION...

... archaea were grown as biofilms on carbon steel coupons under defined laboratory conditions. Once biofilms were established, the coupons were exposed to one of the following corrosion mitigation treatments: (1) simulated pigging using a wire brush, (2) exposure to CI at a concentration of 50 ppm, or (3...

... in-situ show that the initial and mean (after 11 months) current densities are higher than those recommended by the DNVGL RP B401 standard. Even if mean current densities are expected to continue to decrease slowly with further exposure time, so probably tending to the standard recommendations, the DNVGL...

In traditional corrosion testing, panels are painted and scribed, prior to testing in an ASTM B117 salt fog environment and by atmospheric exposure, typically at a beach location. In reality, however, components are usually very complex and held together with fastening systems...
