Overview
Nitron™ Flight coatings are a family of high-performance physical vapour deposition (PVD) coatings have been optimised to overcome problems on mission-critical parts such as:

• Reduce life cost ownership
• Increase aircraft and mission availability
• Reduced Specific Fuel Consumption when applied to turbine blades
• Reduction in CO2 emissions
• Increased in-service temperatures
• Longer on-wing service life
• Weight saving combinations of material, i.e. titanium to replace steel
• Enhanced erosion protection and reduced blade/vane cleaning cycles

These exceptional surface treatments can be applied as either single- or multilayer coatings, and do not require any post-coating polishing or treatment to meet stringent surface finish requirements.

Backed by a well-equipped on-site laboratory with access to SEM-EDX, XRF, optical surface profilometry, scratch testing, nanohardness, UKAS tensile and impact testing, Wallwork Cambridge are able to offer comprehensive support to develop coatings to suit any application.

Results
Based on testing, it was identified:

• Based on testing, it was identified:
• Nitron™ Flight, Grade A gives between 2.7 – 8.7 times more erosion protection over the life of the test compared to uncoated Inconel.
• Nitron™ Flight, Grade B gives between 1.4 – 2.7 times more erosion protection over the life of the test compared to uncoated Inconel.
• Nitron™ Flight, Grade CA gives between 14 – 33 times more erosion protection over the life of the test compared to uncoated Inconel.
