Encapsulation of Linseed Oil & Tung Oil in urea-formaldehyde shells was performed using in-situ polymerization technique. Thin film self-healing coatings with uniform and quick self-healing ability were achieved with microcapsules at concentration of 3 wt%. Anti-corrosive performance was evaluated using immersion test & electrochemical impedance spectroscopy (EIS).

Internal corrosion and sulfide stress cracking (SSC) are problems for steel pipelines transporting natural gas or CO2 containing partial pressures of H2S higher than 0.3 kPa (0.05 psi). The objective of this work is to mitigate internal corrosion and SSC in steel pipelines transporting natural gas containing H2S using cold spray coatings. Two types of the cold spray binary metallic coatings (zinc chromium (ZnCr), zinc niobium (ZnNb)) were studied using electrochemical techniques: potentiodynamic polarization (PDP), linear polarization resistance (LPR), and electrochemical impedance spectroscopy (EIS). The evaluation of the corrosion resistance of cold spray coatings (ZnCr, ZnNb) was carried out in an environment containing 4 bar CO2 pressure, simulating the partial pressures that are found in gas transmission lines over a solution of 3.5 wt.% NaCl heated to 40 °C. To simulate sour conditions, a concentration of 0.003 M Na2S2O3.5H2O, which corresponds to H2S partial pressures around 0.079 bar (1.146 psi), was used. Post-corrosion surface characterization was performed using a scanning electron microscope (SEM) equipped with energy-dispersive X-ray spectroscope (EDS) and X-ray diffraction analysis (XRD). The data showed that the presence of 0.003 M Na2S2O3.5H2O shifted the corrosion potential to more anodic values and decreased the corrosion current density. Bothcoatings showed similar behavior after 1 hour of exposure in CO2/H2S environment, which indicated that similar electrochemical reactions were taking place on ZnNb and ZnCr. SEM images and EDS surface analyses for specimens showed a significant change in surface chemical composition of carbon steel coated with ZnNb and ZnCr, after 24 hours of immersion. No localized attack was observed. The EDS analysis and XRD results revealed the presence of zinc sulfide (ZnS).

Development of Self-healing Coatings by Linseed Oil Encapsulation

Product Number: 51218-169-SG

Author: Haoran Wang, Qixin Zhou

Publication Date: 2018

Self-healing coatings have been promising due to their automatic recovering functions, which can extend the coating lifetime with lower maintenance costs. One of the most effective strategies to achieve self-healing property is to encapsulate healing agents inside microcapsules and integrate the microcapsules into the coating matrix.

Natural gas pipelines are subject to internal corrosion. Internal corrosion of steel pipelines can cause natural gas leakage, leading to wasted energy, explosion hazards, and methane emissions. The U.S. Department of Transport reported numerous case histories of corrosion problems and failures in wet gas pipelines. The National Energy Technology Laboratory (NETL) performed an incident survey from 2010 through 2018 and found that 112 (12%) of these incidents in the U.S. transmission lines were caused by internal corrosion.

Self-healing polymers are a new class of smart materials, which have the capability to autonomically repair themselves after damage, without the need for detection or repair by manual intervention. To expand the scope of practical applications, new self-healing chemistries have been developed and evaluated for use in a wide variety of applications including coatings.

Self-Healing Microcapsule-Thickened Oil Barrier Coatings

Product Number: 51220-250-SG

Low-viscosity oils could potentially act as self-healing barrier coatings because they can readily flow and reconnect to heal minor damage. For the same reason, however, they typically do not form stable coatings on metal surfaces. Increasing viscosity helps to stabilize the oil coating, but it also slows down the healing process. Here, we report a strategy for creating highly stable oil coatings on metal surfaces without sacrificing their remarkable self-healing properties.

Self-Healing Systems for Industrial and Marine Protective Coatings

Product Number: 41211-584-SG

Author: Gerald O. Wilson, H. Magnus Andersson

Publication Date: 2011

$20.00

Truly self-healing materials have the capability to repair themselves when they are damaged without the need for any external intervention. Self-healing systems based on microencapsulated healing agents developed by researchers at the University of Illinois at Urbana-Champaign were initially developed with polymerized resins and reinforced polymer composites as the intended applications. In this paper, we discuss the principles that emerged in the design of these self-healing systems and how they are presently used in design and optimization of self-healing systems for industrial and marine protective coatings.
