Corrosion Inhibition of Carbon Steel in a Sour (H₂S) Environment by an Acryloyl-Based Polymer

ACS Omega (2023)

Muhammad Imran ul‐haq Qasim Saleem Hassan A. Ajwad Rashed M. Aleisa Nayef M. Alanazi

Corrosion poses safety and operational challenges in the oil and gas field, particularly in a sour environment. Corrosion inhibitors (CIs) are thus employed to protect the integrity of industrial assets. However, CIs have the potential to dramatically impair the effectiveness of other co-additives, such as kinetic hydrate inhibitors (KHIs). Here, we propose an acryloyl-based copolymer, previously used as a KHI, as an effective CI. The copolymer formulation provided a corrosion inhibition efficiency of up to 90% in a gas production environment, implying that it can reduce or even eliminate the need for an additional dedicated CI in the system. It also demonstrated a corrosion inhibition efficiency of up to 60% under field-simulated conditions for a wet sour crude processing environment. Molecular modeling suggests that the enhanced corrosion protection is imparted by the favorable interaction of the heteroatoms of the copolymer with the steel surface, potentially displacing adhered water molecules. All in all, we show that an acryloyl-based copolymer with dual functionalities can potentially overcome issues caused by incompatibilities in a sour environment, resulting in significant cost savings and operational ease.

Comparison of Wear Performance of Thermal Sprayed Cermet (WC-Co) Coatings from Suspension and Feedstock Powders

Thermal spray (2017)

Omar M. Ali R. Ahmed Hussain Alawadhi Mohamed Shameer Nadimul Haque Faisal

Abstract WC-Co coatings were deposited using conventional High Velocity Oxy-Fuel Jet-Kote (HVOF-JK) and Suspension HVOF (S-HVOF) methods. Microstructural and mechanical properties along with the wear resistance of coatings were investigated. Reciprocating sliding wear tests were conducted against sintered Si3N4 counter-body with a normal load of 25N and total sliding distance of 500m following ASTM G133-2 standard. Coatings were characterised by Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD) and nano-Indentation techniques. HVOF-JK coating showed good retention of WC whereas S-HVOF coating showed the presence of W, W2C and amorphous/nanocrystalline phases. Nano-indentation of HVOF-JK and S-HVOF showed that the relative hardness of the HVOF-JK coating was higher but their elastic modulus was lower. The lower total wear rate was exhibited by the HVOF-JK coating. This difference in wear performance is attributed to the difference in hardness of the coatings and decarburisation of WC particles.

Nanoindentation Evaluation of Suspension Thermal Sprayed Nanocomposite WC-Co Coatings

Key engineering materials (2017)

Omar M. Ali Rehan Ahmed Nadimul Haque Faisal Nayef M. Alanazi Y. O. Elakwah

The aim of this paper is to evaluate the microstructural and nanohardness characteristics of tungsten carbide-cobalt (WC-Co) cermet coatings deposited by liquid suspension spraying. Commercially available WC-Co coating powder was milled and water based suspension was produced as feedstock for the thermal spray coating process. Microstructural evaluations of WC-Co cermet coatings included XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscopy). Post spraying nanomechanical evaluations were conducted using a Berkovich nanoindenter. Results indicated relatively higher modulus but lower hardness of suspension coatings. The load displacement curves during nanoindentation were characteristic of the complex coating microstructure showing signs of microcracking and pile-up.

Influence of Residual Stresses on Corrosion and Wear Behavior of Electrodeposited Nanocrystalline Cobalt-Phosphorus Coatings

International Journal of Electrochemical Science (2013)

Nayef M. Alanazi A.M. El-Sherik Saleh H. Alamar Shouwen Shen

Electrodeposited nanocrystalline Cobalt-Phosphorus (Co-P) alloy coatings deposited onto carbon steel substrates at different phosphorous contents (0.0 wt%, 3 wt% and 10 wt%) were investigated for the influence of residual stress on their corrosion and wear behaviors. X-ray diffraction technique was employed to determine the average crystallite size and residual stresses. The electrochemical corrosion behavior of Co-P coatings compared with a pure nanocrystalline cobalt coating was investigated using open circuit potential and potentiodynamic polarization scans. Wear resistance of electrodeposited nanocrystalline Co-P coatings was tested using pin-on-disc tribometer. The experimental results showed that with increasing phosphorous content, the average crystallite size decreased and coating compressive residual stresses increased. Also, the experimental results revealed that wear and corrosion resistance of Co-P coatings initially increased with increasing compressive residual stress of coating reaching a maximum at residual stresses of 450 MPa and 500 MPa before dropping with further increase in the compressive residual stress.

Comparative Study of Corrosion Performance of HVOF-Sprayed Coatings Produced Using Conventional and Suspension WC-Co Feedstock

Journal of Thermal Spray Technology (2018)

Rehan Ahmed G. Vourlias Ahmed Algoburi C. A. Vogiatzis D. Chaliampalias

Corrosion properties of nanostructured coatings deposited by suspension high-velocity oxy-fuel (S-HVOF) via an aqueous suspension of milled WC-Co powder were compared with conventional HVOF-sprayed coatings. Microstructural evaluations of these coatings included x-ray diffraction and scanning electron microscopy equipped with an energy-dispersive x-ray spectroscopy. The corrosion performance of AISI440C stainless steel substrate and the coatings was evaluated in a 3.5 wt.% NaCl aqueous solution at ~ 25 °C. The electrochemical properties of the samples were assessed experimentally, employing potentiodynamic polarization and electrochemical impedance spectroscopy. The potentiodynamic polarization results indicated that coatings produced by S-HVOF technique show lower corrosion resistance compared with the coatings produced by HVOF-JK (HVOF Jet Kote) and HVOF-JP (HVOF JP5000) techniques. Results are discussed in terms of corrosion mechanism, Bode and Nyquist plots, as well as equivalent circuit models of the coating–substrate system.
