The objective of this work is to investigate and develop alternative wear-resistant coatings applied by a novel coating technique to improve performance of aircraft landing gear components (LGC). The selected Electro-magnetically enhanced Physical Vapor Deposition technique is developed to apply… More

The objective of this work is to develop and demonstrate a novel surface engineering concept for protection of Aircraft Brake Pressure Plates. Carbon-made aircraft breaking system components experience increased service temperatures and, when swiped by the temp stick, chemically react with the… More

The objective of this work is to investigate and develop dense corrosion resistant coatings to improve performance of aircraft components (AC). Cadmium metal (Cd), although a hazardous substance, is still being used as a sacrificial coating on majority of AC component. The PVD-based technique is… More

Landing Gear components (LG) are protected from in-service wear by application of hard Chromium (Cr). The porosity and columnar structure of the currently utilized galvanic Cr coatings allow corrosive media to penetrate through dramatically decreasing the life span of the component. For the… More

Majority of Aircraft Components (AC) is protected from corrosion by application of galvanic Cadmium (Cd). In some instances, mostly for the non-line-of-site configurations, Cd is replaced by Aluminum (Al) which is applied by Ion Vapor Deposition (IVD). The porosity and columnar structure of the… More

Carbon fiber-based brakes are made out of so-called carbon-carbon composite material (CC) that consists of two components: weaved carbon cloth and solid carbon matrix. The limitations of oxidation protection systems for CC, especially in long duration, cyclic and/or reusable applications, have made… More

Steel bearings are being used on numerous weapon systems currently employed by many organizations of the Department of Defense including the Air Force. Due to continuous exposure to cruel weather environments, corrosion and lack of maintenance, bearings endure pre-mature failures. Composite… More

Numerous power sources are currently in use by the US military. Over 80% of the logistics re-supply is battlefield fuel. Diesel generators have been traditionally employed for both stationary and portable power units. Where weight and volume are presently a major concern the military is seeking to… More

Various attempts have been made to replace electrodeposited chromium applied to internal surfaces of gun barrels. In this activity Advanced Global Services (AGS) will validate a novel coating technique to apply advanced non-hazardous erosion resistant materials to medium caliber gun tubes. The… More

Steel bearings are used on numerous weapon systems (WS) currently employed by many organizations of the Department of Defense (DOD) including the Air Force. Most components are usually protected from corrosion by coatings. Coatings can create a corrosion barrier for the base steel material and the… More

Many attempts have been made to replace electro-deposited chromium applied to internal surfaces of gun barrels. The patented EPVDT process has been bench-marked by DOD programs as a fit substitute. EPVDT has already proven its capability by producing a multitude of coatings not unavailable with… More

Aluminum-made LG outer cylinders easily become damaged developing nicks and scratches of 5 thousandths of an inch or deeper on the inner surface (ID). This leads to a premature condemnation. There is currently no repair technique to restore the LG outer cylinders to serviceable condition. The EPVDr… More

Many attempts have been made to replace electro-deposited chromium applied to internal surfaces of gun barrels. Patented EPVDr process has been bench-marked by DOD programs as a fit substitute. The objective of the proposed work is to continue the investigation and development of erosion resistant… More

ABSTRACT: Landing Gear (LG) is one of the few critical elements which are not redundant and failure usually results in catastrophe. Current inspections center on macro aspects of fatigue in that they are only applicable during the crack propagation phase and fail to identify and sense stages of… More
