Carburizing and Heat Treatment of Carburizing Grade Steel Parts

2019-04-15
CURRENT
AMS2759/7D
This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements and procedures for three classes of gas, vacuum, liquid, and low pressure (LPC) carburizing and related heat treatment of parts fabricated from carburizing grade steels. Parts made from steels other than those specified in the detail specifications may be heat treated in accordance with the applicable requirements using processing temperatures, times, and other parameters recommended by the material producer unless otherwise specified by the purchaser. This specification does not cover pack carburizing.

Anodic Treatment of Aluminum Alloys Sulfuric Acid Process, Undyed Coating

2019-03-25
WIP
AMS2471J
This specification establishes the requirements for undyed anodic coatings on aluminum alloys. This process has been used typically to increase corrosion resistance and to provide surfaces that will promote adherence of paint and other organic finishes, but usage is not limited to such applications. AMS2472 should be specified for coatings colored by dyeing. This process is not suitable for parts that contain joints or recesses in which the anodizing solution may be retained.

Cleaning and Preparation of Metal Surfaces

2019-03-12
WIP
AMS03_2B
This SAE Standard specifies processes for the cleaning of metal surfaces to remove any extraneous or undesirable material or deposits at any stage of manufacture, storage or service and for the preparation of these surfaces for further treatment. Any necessary stress-relieving treatments are also included. This Standard does not override special preparatory procedures specified in individual Defence Standards, Defence Specifications, DTD Process Specifications, DG Ships Specifications and Naval Defence Standards. It also does not cover cleaning operations associated with the maintenance of internal combustion engines, the preliminary removal of heavy deposits of oil, grease, or dirt accumulated during operational service, preparations for welding and the cleaning of electrical contacts.
Standard

Vacuum Gauge Calibration

2019-03-06
CURRENT
ARP7446
This SAE Aerospace Recommended Practice (ARP) addresses the general procedure for the best practices for minimizing uncertainty when calibrating thermal conductivity and cold cathode vacuum gauges, which includes the vacuum sensor(s) and accompanying electronics necessary for a pressure measurement to be made. It also includes the best practices for an in-process verification where limitations make it impossible to follow the best practices for minimizing uncertainty. Verifying the accuracy and operation of vacuum gauges is critical to ensure the maintenance of processes while under vacuum.
