Both substrate cleanliness and surface...

...Abstract Thick-film epoxy coating systems are applied at greater dry film thicknesses than conventional protective coating systems, resulting in a greater need for achieving the required level of surface preparation. They also must serve in corrosive and severe environmental conditions and must...

...Both systems exhibit improved performance with the novel surface engineering approach, with System 2a exhibiting a 0.37 mm improvement in the scribe creep value and System 2b with an even larger 1.25 mm better scribe creep over the traditional blasting surface preparation. After coating, the panels...

...Two-Dimensional (2D) profiling Surface Treatment Practices A surface preparation of corrosion coupons for weight loss measurements and/or electrodes for electrochemical testing is a critical step during the lab evaluation of corrosion inhibitors. The most used methods are as follows...

...DISCUSSION AND CONCLUSIONS It was evident from the failure investigation that the coating surface preparation failure was attributed to the improper pipe manufacturing quality and field fabrication processes. Despite being a separate field, piping manufacturing quality and field fabrication...

...Abstract The purpose of this work is to study the impact of the quality of steel surface preparation and the level of soluble salt contamination on the performance and durability of protective coating systems. Steel panels were prepared using a standard method and controlled levels of salt...

...INTRODUCTION Structures in restricted areas have always faced the problem of how to carry out maintenance and repair of their coating systems. The surface preparation techniques that can be used in such areas all carry with them problems relating to the long term performance of the anti-corrosive...

... activity. An analysis of the coating systems and surface preparation that are currently used, as well as of historic records of the plant equipments revealed opportunities to improve the coating systems performance in the future. Modern coating systems and practices were discussed, benchmarked and a final...

... is the focus for this study. Success of the coating work depends on many aspects (paint specifications, paint systems certification, surface preparation, coating application, certified inspectors activity, etc), but mainly it depends on the environmental conditions and procedures used to counteract...
