Role of Ca2+ in the CO2 corrosion behavior and film characteristics of N80 steel and electroless Ni–P coating at high temperature and high pressure

Electroless deposition of Ni–P/Au coating on Cu substrate with improved corrosion resistance from Au(iii)–DMH based cyanide-free plating bath using hypophosphite as a reducing agent

“… 48,55,56 Copper peaks were present at 2 θ = 43.7°, 50.8°, and 74.4° due to the copper substrate, and the very broad peaks at 44.7° were ascribed to the (111) of amorphous Ni–P alloy. 57 The Au (111), Au (220), and Au (300) diffraction peaks were detected at 38.6°, 65.1°, and 78.0°, respectively, and the Au (111) was the preferred orientation. The XRD patterns of the gold peaks of five kinds of coatings were similar, indicating that the addition of NaH 2 PO 2 did not affect the crystal structure of gold regardless of the NaH 2 PO 2 concentration.…”

Insight into polymer concentration, temperature, CO2 content, and Cl− content on corrosion of N80 steel tubing in polymer flooding

“…The peak binding energy of the C 1s spectrum divides into three peaks (289.09, 284.29, and 286.53 eV) which are corresponding to FeCO 3 and polymer respectively, as shown in Figure 4a. The peak binding energy of the O 1s spectrum consisted of three peaks, those of which are attributed to FeCO 3 and polymer respectively [38] (Figure 4b). The binding energy peaks of Fe 2p spectra are composed of Fe 2p3/2 (711.49 eV), Fe 2p1/2 (719.50 eV), and Fe2p 1/2 4c).…”
