Download or read book Validation of HVOF WC Co Thermal Spray Coatings as a Replacement for Hard Chrome Plating on Aircraft Landing Gear written by and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hard chromium electroplating is extensively used by aircraft manufacturers and military maintenance depots to provide wear and/or corrosion resistance or to restore dimensional tolerance to components. However, chrome plating utilizes hexavalent chromium, which is a highly toxic carcinogen, and increasingly stringent environmental and worker-safety regulations are making chrome plating more expensive for the DoD. This document constitutes the final report on a project to quality high-velocity oxygen-fuel (HVOF) thermal spray WC/Co coatings as a replacement for hard chrome plating on landing gear components. Extensive fatigue, wear, corrosion, impact, and hydrogen embrittlement test results comparing the WC/Co coatings against hard chrome are presented. The results of rig and flight-testing of HVOF WC/Co coatings on landing gear components are also presented. in general, the performance of the WC/Co coatings was superior to hard chrome. Producibility issues such as stripping, grinding, and non-destructive inspection of the coatings were addressed. Cost/Benefit analyses indicate that military repair depots that overhaul landing gear can realize substantial savings by converting from hard chrome to HVOF. Specifications were developed for the WC/Co powder, the coatings deposition parameters, and the grinding of the WC/Co coatings.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrolytically deposited chrome plate is the current standard surface treatment for landing gear component interface surfaces that require good wear resistance and corrosion protection. Chrome plated components are typically plagued by a slight debit in fatigue performance, detrimental mud cracking surface pattern, susceptibility to scoring, wear, and seal leakage. In addition, recent changes in environmental compliance standards place further restrictions on the use of electrolytically deposited chromium. Some commercial applications have already eliminated the use of chrome plate on current and future products. As a result, a substitute for electrolytically deposited chrome plate has been sought for several years.High Velocity Oxygenated Fuel (HVOF) thermal spray coatings have been developed to the point where they are being implemented as an alternative to hard chrome plate on high strength low alloy steels for external surfaces on landing gear applications. Some of the characteristics of HVOF coatings, such as fatigue and wear resistance are superior to hard chrome plate. Yet, performance characteristics, such as adhesion under very high strains, are clearly different. This document is intended to outline and describe the design and usage guidelines for HVOF tungsten carbide coatings to assure adequate quality and performance of the landing gear equipment. This document is not intended to act as a detailed process specification for applying HVOF coatings. Also, the recommendations in this document do not necessarily apply to certain proprietary spraying systems (i.e., D-Gun).The information in this document pertains to HVOF tungsten carbide based coatings applied to high strength steel alloys only, and is not necessarily applicable to other substrates. ARP5935 has been reaffirmed to comply with the SAE five-year review policy.

Download or read book Replacement of Chromium Electroplating on Gas Turbine Engine Components Using Thermal Spray Coatings written by and published by . This book was released on 2005 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hard chromium electroplating is extensively used by aircraft manufacturers and military maintenance depots to provide wear and/or corrosion resistance or to restore dimensional tolerance to components. However, chrome plating utilizes hexavalent chromium, which is a highly toxic carcinogen, and increasingly, stringent environmental and worker-safety regulations are making chrome plating more expensive for the DoD. This document constitutes the final report on a project to qualify high-velocity oxygen-fuel (HVOF) and plasma thermal spray coatings as a replacement for hard chrome plating on gas turbine engine components. Extensive fatigue, fretting wear, salt-fog corrosion, and carbon-seal wear tests were performed on HVOF, WC/17Co, Tribaloy 400, Tribaloy 800, and Cr3C2/20(NiCr), and plasma-sprayed Tribaloy 400 coatings compared to hard chromium. In general, the HVOF WC/17Co coatings demonstrated superior performance. An accelerated test on a TF33 engine containing seven components coated with HVOF WC/17Co showed superior performance to what would have been expected using the standard hard chromium. A cost/benefit analysis indicates that military repair depots that overhaul gas turbine engines can realize substantial savings by converting from hard chrome to HVOF.
