Among the various corrosion protection strategies for structural steels, coating techniques provide the most cost‐effective protection and have been used as the primary mode of corrosion protection. Existing coating techniques however have been used mainly for their barrier capability and therefore all have a limited service life due to oxidation aging, electrolytic degradation, or various inadvertent defects and flaws occurred in and after coating applications. This work investigated the anti‐corrosion potential of a π‐conjugated polymer—polyaniline (PANi), which was doped into an intrinsically conducting polymer and then included in a two‐layer coating system as a primer layer. To achieve a long service life, the primer layer was made by mixing the conductive PANi in a waterborne poly‐vinyl butyral solution to provide strong adhesion to steel surface, and then topcoated with a layer of elastomer‐modified polyethylene to obtain extra mechanical and barrier protections. Two ASTM standard tests were conducted to evaluate the corrosion durability and tensile adhesion of the two‐layer system, in which the system demonstrated superior performance. The Scanning Kelvin Probe Force Microscopy (SKPFM) was used to provide the microscopic evidences for the outstanding performance. Microsc. Res.

In this paper a number of factors that influence the corrosion level of a metal gas pipeline in the ground are described. We consider the parameters that are used in the electrometric diagnostics of corrosion protection. The key requirements and the types of work on the organization of the corrosion inspections of OAO Gazprom’s underground facilities are listed. As a result of an analysis of numerous works, we selected the most significant requirements. The real practical results of corrosion inspections were demonstrated. 相似文献

Experimental results on the thermal nondestructive testing (NDT) of corrosion simulators in 6- and 10-mm-thick steel products are presented. The need for the processing of infrared thermal images via a Fourier transform and principal component analysis (PCA) is demonstrated. The ultimate capabilities of the thermal method are estimated at a level of 20% material loss. 相似文献

The work of the corrosion protection system used at OOO Gazprom Transgas Yekaterinburg is considered, mainly for the period of 2008. It is noted that the passive corrosion protection component, which consists of different pipeline wrappings, requires repair and replacement. The active (electrochemical) corrosion protection component achieves a high level of corrosion protection of gas pipelines via the application of different technical processes. Their work is exemplified by the main gas pipelines of the Nev’yansk Regional Gas Pipeline Operation Center. 相似文献

Hard disks with different roughness levels have been coated with hydrogenated and/or nitrogenated carbon using magnetron sputtering and plasma beam based carbon guns. The plasma beam is generated by means of the self bias effect of an asymmetric, magnetically enhanced rf glow discharge. Acetylene is used in the sub-μbar pressure range. The ion impact energy was approx. 190 eV/carbon atom, as opposed to typically <10 eV for the sputtered atoms. Hard disks have been coated with 2–10 nm a-C:H. They were subjected to a hot–wet environment for 4 days. The corrosion was measured by the cobalt extraction test. For either mode of deposition it was confirmed that disk surface roughness considerably affects the corrosion protection achieved by the respective carbon top coat. Plasma beam deposition yielded a better corrosion protection than sputtering. 相似文献
