Aerospace Coatings Process Specifications
AMS 2437 is a specification for an array of coatings used in plasma spray applications. This process uses high-energy plasma to deposit coatings onto surfaces. The resulting coatings are dense and well bonded, making them ideal for use in many high-wear applications. AMS 2437 coatings can be applied to a variety of materials, including metals, ceramics, and plastics. The coatings are typically applied in a thin layer, typically less than 1 millimeter thick. Plasma spray deposition is a versatile process that can be used to create a variety of different coating types, including metallic and ceramic coatings.
AMS 2447 covers the HVOF class of thermal spray coatings that have been designed to offer corrosion resistance and wear resistance superior to most plasma coatings. The coatings are applied using a high velocity oxy-fuel (HVOF) process, and they are typically used in applications where there is a need for high coating density and superior bond strength. AMS 2447 is most commonly specified for high wear applications involving metal on metal contact, fine particle erosion, or extreme heat and wear.
AMS 2448 covers HVOF applications of tungsten carbide coatings for aerospace applications.Coatings in this class offer exceptional wear resistance and high impact toughness. These coatings are intended for use on Ultra High Strength Steels (UHSS), and are essential protective surfaces for the aerospace industry. Tungsten Carbide AMS 2448 specification coatings can also be used on other metals and alloys, providing a versatile solution for a wide range of industries and applications.
