Wallwork Cambridge's advanced thin film NITRON FLIGHT technology applies graded coatings, precision-engineered in thickness and composition, to critical flying parts such as turbine blades and other high stress components. These coatings, from 3 to 30 microns thick and hardnesses up to 3000HV, offer
- reduced wear and friction,
- reduced total life costs,
- extended maintenance intervals,
- increased corrosion resistance
- reduced specific fuel consumption,
- allow substitution of lighter weight design/materials
Wallwork Cambridge's Nitron Flight coatings, have achieved dramatic reductions of erosion wear on Ti6/4 alloy surfaces. Comparative wear tests carried out by Wallwork Cambridge on Ti6/4 samples revealed that Nitron Flight coatings reduced abrasive wear by more than 75%. Nitron coatings, can be applied to titanium, steel and advanced alloy surfaces, such as engine blades/vanes for operation at temperatures up to 1000 degrees Centigrade. The coatings are applied in a duplex process using physical vapour deposition (PVD) to apply a variety of hard thin film nitron flight coatings in a variety of basic formulations of metal nitrides (Nitron A,B,CA & O), and in a variety of single and multiple layer coatings to suit specific applications.
New White Paper on Alternatives to Hard Chrome Plating
Hard Chrome Plating (HCP) was scheduled to be outlawed by the end of 2019, however, the sunset date has been extended by a few years. This has not stopped leading manufacturers across all sectors from implementing their long developed replacement strategies. As companies review the options, Ian Haggan, business development manager for hard coatings at Wallwork Group, proposes processes that have significant performance advantages. Download it here.
New Datasheets: Xylan and Molybdenum di-Sulphide
Xylan®, based upon the Whitford Xylan® family of coatings, are first and foremost dry film lubricants (DFL); however, they have many desirable secondary properties. These lubricants are combined in a matrix with the newest high temperature organic polymers resulting in ‘polymeric alloys’ formulated to provide unique and desirable properties.

Molybdenum di-Sulphide [MoS2] is one of the most lubricious coatings currently available. It has a dynamic coefficient of 0.01 and provides an exceptionally low slip surface, which can be used over a wide range of temperatures from cryogenic levels up to 400°C (fully run-in). MoS2 has the unique ability to lubricate precision components used within an extensive industrial sector spectrum. Read the full data sheet here.
