Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made of the degree of protection against corrosion provided to aircraft fasteners by high purity aluminum coatings versus the normal treatments - cadmium plating on steel and anodize on aluminum. Fasteners included aluminum and titanium rivets, titanium hi-loks, and steel lockbolts. Coating included cadmium plating, anodizing, aluminum (applied by two processes), zinc chromate primer (wet and encapsulated), and aircraft fuel tank sealant. The aircraft had been in service for approximately 24 months at the time of the final inspection. Three field inspections were conducted. The report contains the details of the third, and final, inspection, and also is the final summary technical report of the entire Phase II field service evaluation. Some of the results are very significant. Toward the primary purpose they showed conclusively that aluminum coatings protect steel fasteners and prevent damage to adjacent structure much more completely than conventional cadmium plating. Titanium fasteners also perform much better than cadmium plated steel fasteners. These results showed no significant trends as far as aluminum rivets are concerned. These results did show a very significant advantage for zinc chromate primer over fuel tank sealant in protecting cadmium plated steel fasteners and in preventing corrosion of the adjacent structure. Further, two important trends seemed to be indicated: encapsulated zinc chromate primer seems to be even more effective than normal wet applied zinc chromate primer, and titanium fasteners must be insulated from the adjacent aluminum structure to prevent galvanic corrosion which had begun to develop.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this program is to evaluate the corrosion protection provided by coatings applied to various fasteners used for aircraft skin attachment. On a production HC-130H aircraft, 7,590 fasteners were installed in four test areas. Fasteners included aluminum and titanium rivets, titanium Hi-loks, and steel lockbolts. Coatings include cadmium plating, anodizing, aluminum coatings, zinc chromate primer and aircraft sealant. The test aircraft has been delivered to the Air Force and will be jointly surveyed in the field by the Contractor and the Air Force Materials Lab for an 18-month period at 6-month intervals.

This book was released on 2007 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation Eleven peer-reviewed papers provide the latest information on the structural integrity of fasteners, including the effect s of environmental and stress corrosion cracking. For Sections cover:Fatigue and Crack Growth Experimental Techniques?three papers cover the development of a fastener structural element test for certifying navy fasteners material; experimental crack growth behavior for aerospace application; and influence of cold rolling threads before and after heat treatment on the fatigue resistance of high strength coarse thread bolts for multiple preload conditions. Design/Environmental Effects?two papers examined the relationship between the tightening speed with friction and clamped-load; and the optimum thread rolling process that improves SCC resistance to improve quality of design. Fatigue and Crack Growth Analytical Techniques?three papers describe current analytical techniques for fatigue and crack growth evaluations of fasteners; a numerical crack growth model using the finite element analysis generated stress field; and s the resistance of high strength fine thread bolts for multiple preload conditions. Design Consideration?focuses on the comprehensive nonlinear 3D finite element model to simulate a displacement controlled for riveted structure; state-of-the-art fatigue crack growth analysis techniques which are used in various industries to damage tolerance evaluation of structures; and the material stress state within the thread of the bolt; and on each parameter affecting the structural integrity of a bolted joint.

This book was released on 2012-12-06 with total page 2093 pages. Available in PDF, EPUB and Kindle. Book excerpt: These Proceedings, consisting of Parts A and B, contain the edited versions of most of the papers presented at the annual Review of Progress in Quantitative Nondestructive Evaluation held at University of San Diego, San Diego, CA, on July 27 to August 1, 1997. The Review was organized by the Center for NDE at Iowa State University, in cooperation with the Ames Laboratory of the USDOE, the American Society of Nondestructive Testing, the National Institute of Standards and Technology, the Federal Aviation Administration, and the National Science Foundation IndustrylUniversity Cooperative Research Centers. This year's Review of Progress in QNDE was attended by approximately 370 participants from the US and many foreign countries who presented a total of approximately 350 papers. As usual, the meeting was divided into 36 sessions with four sessions running concurrently. The Review covered all phases of NDE research and development from fundamental investigations to engineering applications and inspection systems, and methods of inspection science from acoustics to x-rays. The Review continues to experience some fluctuations in size, mostly under pressure from a decrease in funding for NDE research at the US Federal level, but increased participation from foreign laboratories has more than made up the difference. The Review is ideally sized to permit a full-scale overview of the latest developments in a collegial atmosphere that most participants favor. The opening plenary session this year concentrated on advances in imaging technologies and methodologies that have been made in recent years. Dr. K.
