... were observed close to the crack along with a distinctly etched region. An expanded macro-etch was then performed to include the areas containing the grinding marks, which then revealed the entire weld zone region – indicating a weld repair of a pre-existing crack (three welding passes) was performed...

... occurs, identifying potential internal corrosion locations is crucial for mitigation and repair. Two main methods are utilized for identifying potential locations of internal corrosion: ILI and ICDA. In-Line Inspection ICDA methodology for pipelines carrying normally dry natural gas can be found...

...Abstract An ongoing research project seeks to provide recommendations for time of inspection of reinforced concrete structural elements susceptible to carbonation-induced concrete and its repair with ultra-high performance concrete. The risk of steel corrosion can vary depending on several inter...

... are recent development in cold spray coatings applications. The intention of this investigation is to understand the viability of hand-applying cold spray patches for in-field repair. Cross-sections of hand-applied cold spray layers of A96061 on A97050 plate were compared to those achieved by a robot...

...Abstract Brush plating is an industrial electroplating process designed for OEM and repair applications without the use of an immersion tank. Many applications require well-engineered and proven coatings that pose as little risk as possible to both the operator and the environment. Zinc-nickel...

...Abstract Non-chromate conversion coatings compliant with MIL-DTL-5541 ¹ have been demonstrated to provide protection comparable to their chromate counterparts. Repair materials are available to address defects in bath-applied conversion coatings from most manufacturers...
