Solid State Additive Manufacturing: Better Results
Enable Slim Line Forging
Extreme Build Speed
Production Quality
Scalable Technology
Additive Friction Stir (AFS) is a solid-state process that creates Near Net Shape Components with near wrought properties. All types of powder and solid metals and reinforcement particles can be used.
Save on time and cost by standardizing slim line forgings and using AFS to build features achieving final part geometry.
Additive Friction Stir creates fully-dense parts with near wrought properties and low residual stress, which allows the manufacture of production quality parts.
This process offers high strength, high ductility, and equiaxed grain structure right off the machine. No post processing is required.

Cold-sprayed Inconel 625 coatings (P. Poza, et al., Surface & Coatings Technology (2012), Doi:10.1016/j.surf-coat.2012.03.018)
In 625 - Filler materialAverage grain size: ~ 12 µm
BSD results depict fine equiaxed grain (1.3 microns max) structures formed by dynamic re-crystallization (DRX). Even finer grain structures form at the layer interfaces (0.26 microns).
After AFS processing, Inconel 625 has upwards of 4X the cycles to failure compared to the IN625 bar stock.
After AFS processing, Inconel 625 has 35% less wear than clad and 41% less wear than cast material.
