This specification covers the requirements for vacuum deposited cadmium
14-day material test to determine the cyclic effects of runway deicing compounds on cadmium plated parts
This SAE Aerospace Information Report (AIR) is intended to document and provide access to information obtained by an industry survey. It summarizes and documents data regarding possible alternatives to the use of cadmium plating on general connectors and connector accessories typically used in aerospace and military defense electrical interconnect systems
This SAE Aerospace Information Report (AIR) describes the performance of plating’s and coatings for landing gear that potentially provide environmental compliance benefits versus the current baseline processes. The hazardous systems addressed in this version of the document include cadmium plating, chromated primers, and high VOC (volatile organic compounds) topcoats. The AIR applies to landing gear structures and mechanisms for all types of civil and military aircraft. The potential replacements apply to both Original Equipment Manufacturer (OEM) hardware and overhaul of in-service landing gears
This specification covers the requirements for electrodeposited cadmium plating
It is both an exciting and a difficult time for the aerospace industry. While the sector is at its most buoyant with demand soaring in the commercial market, this is placing a strain on the manufacturing supply chain, and putting the MRO (maintenance, repair and overhaul) market under pressure to keep aircraft in operation for as long as possible. In addition, OEMs and MRO businesses are being forced to consider potential ever-evolving legislation, particularly regarding the use of various chemicals used in the plating process, most notably the use of cadmium. This toxic metal has long been the topic of debate in the industry, with companies facing the threat of a European ban on cadmium being extended to the global aerospace industry if studies into possible alternatives prove fruitful
14-day material test to determine the cyclic effects of runway deicing compounds on cadmium plated parts
A University of Chicago research team has created a new solder for semiconductors. After being heated to several hundred degrees Celsius, the compounds of cadmium, lead, and bismuth can be applied as a liquid or paste to join two pieces of a semiconductor
For certain semiconductors with important applications, the existing bulk crystal growth technique from the melt usually results in poor-quality multi-crystalline ingots that cause the typically low yield of the commercial growth process. The low-quality, multi-grained crystal growth is mainly caused by the large supercool of the melt, which prohibits the ideal growth condition that a small, single-crystal nucleus forms at the very tip and grows into a large single crystal. For instance, semi-insulating cadmium zinc telluride (CdZnTe) crystal is a highly promising material for room-temperature x-ray and gamma ray detectors. However, the major hurdle in using the CdZnTe crystals is its cost. The ability to pack many data acquisition channels (hundreds) with the stopping power for high-energy radiation requires large single crystals of CdZnTe
This SAE Aerospace Information Report (AIR) describes the performance of platings and coatings for landing gear that potentially provide environmental compliance benefits versus the current baseline processes. The hazardous systems addressed in this version of the document include cadmium plating, chromated primers, and high VOC (volatile organic compounds) topcoats. Available data are presented for various standard tests in order to compare the replacement candidates. Conclusions are made as to the best performer(s) for each test section presented. These conclusions are not to be regarded as recommendations for or against any of the candidates. The AIR applies to landing gear structures and mechanisms for all types of civil and military aircraft. The potential replacements apply to both original equipment manufacturer (OEM) hardware and overhaul of in-service landing gears
