Military & Aerospace Applications
Boost part life, reduce cost of components, Improve efficiency.
DYNA-BLUE® surface treatments reduce wear, increase fatigue resistance, and deliver longer part life for high-load drivetrain and engine assemblies, cutting costs and improving component reliability.
Extend the Life of Gears, Shafts, and Critical
Components with DYNA-BLUE® & NITROWEAR
Modern military and aerospace components operate under harsher environmental conditions than ever before. with higher demands for improved wear resistance, tighter tolerances and longer life. Gears, shafts, and other engine components must perform consistently through extreme pressure, vibration. temperature, and corrosion exposure. Small arms and weapon systems need high wear, heat and corrosion resistance.
DYNA–BLUE® solves the wear and performance challenges of these systems with a low-temperature diffusion treatment that hardens the surface without compromising ductility or dimensional accuracy. The result is a durable, high-performance component with longer service life. lower friction. and better fatigue resistance.
Why DYNA-BLUE® Is Trusted for Military and Aerospace applications
Common Problems We Solve
-
Part failure due to wear or fatigue
-
Shaft galling and bearing surface degradation
-
Corrosion from heat, fluids, or atmospheric exposure
-
Microfractures from torsional stress and vibration
-
Scrap from coating or paint flaking, exposing surface to environment
-
Premature failures requiring costly replacements
OYNA-BLUE® forms a metallurgical bond within the steel itself, producing a compound zone of 75+ HRC hardness supported by a diffusion layer up to 0.020″ deep. Unlike chrome or nickel plating, salt or gas nitriding,, DYNA-BLUE® doe,;n’t flake, chip, or require line-of-sight. It delivers uniform hardness across all surfaces
including gun barrel bore,., shafts, gears and other complex geometries.
Key Benefits:
-
Up to 10x more wear resistance than salt bath Ion/gas nitriding or chrome

Increased part life and reduced part failure
-
Increased wear and fatigue resistance
-
Dimensional stability: 0.0001–0.0002″ growth per side
-
Corrosion resistance with optional NITROWEAR® add-on
-
Resists softening even at elevated temperatures
-
Compatible with carbon & alloy steels, cast irons, and stainless steels
-
Fast turnaround: 1-2 days typical
-
