AMS 2750 pyrometric requirements for heat treatments: what's new in revision F

AMS 2750 (Aerospace Material Specifications) is an aerospace international specification which covers the pyrometric requirements for plants used for the heat treatment of metallic materials. Specifically, it covers temperature sensors, instrumentation, plant equipment, correction factors and offsets of instruments, system accuracy testing and temperature uniformity testing. These are necessary to ensure heat treatment of parts or raw materials in accordance with applicable specifications.

The AMS 2750 is now in revision F, was revision E from July 2012.

Let's see what’s new.

Learn all about coating the additive manufactured Titanium64 [2/2]

In the previous article we’ve seen how AlTiN thin film deposition process was carried out via reactive Physical Vapor Deposition High-Power Impulse Magnetron Sputtering (PVD HiPIMS) to coat Ti6Al4V substrates, realized via Selective Laser Melting (SLM).
Two different SLM process conditions were employed for modifying the obtained part surface morphology and, later, the samples were heat-treated under high vacuum.

Do not miss this in-depth investigation and the conclusions at the end, we’ll provide you all the information to get the most out of these three technologies.

Learn all about coating the additive manufactured Titanium64 [1/2]

Among the industrial AM technologies, selective laser melting (SLM) is the most widespread, thanks to its process stability and its favorable ratio between costs and part quality. However, selective laser melted products require coatings for functionalizing the surface with extra properties and in this article we’ll see how thin film deposition process can be carried out to coat titanium substrates.

Is it possible to coat the titanium alloy substrates to obtain a good improvement of the mechanical surface features?
What’s the role of vacuum heat treatments on additive manufactured parts?
Can the laser scanning paths affect the resulting adhesion of the coatings?
