Our proprietary Low Energy Cladding (LEC) process allows us to apply highly wear-resistant hardmetal coatings – such as WC-Co – to a wide range of steel components with outstanding precision and efficiency. The process introduces almost no thermal energy into the part/substrate, preserving base material properties and enabling near distortion-free coating, even on thin-walled or delicate components. LEC creates a true welded metallurgical bond, ensuring ideal adhesion and mechanical strength – even under dynamic load and thermal cycling. 

Beyond wear protection, LEC enables the creation of customized surface structures tailored to the functional demands of your application. We can freely define the pattern geometry – such as crosshatch, wave, or directional textures – to fine-tune the friction coefficient. Depending on the design, we can achieve a targeted coefficient of friction between 0.2 and 0.6 (LEC coating on steel), offering a precise balance between grip and surface durability. These engineered textures are ideal for use in:

• Torque-transmitting friction pads
• Grip-enhancing structures for Face/Duo Cone Seal housings
• Rotational stop or anti-slip interfaces in mechanical assemblies

With LEC, you gain functional performance, tailored friction control, and material efficiency – all in one integrated surface solution. An actual LEC-coated housing example is introduced below.

Our LEC technology enables the application of precisely textured, highly wear-resistant hardmetal coatings to steel housings for Face / Duo-Cone Seals – with minimal thermal input and outstanding adhesion.

In rotary sealing systems, especially under high-pressure conditions or in the presence of mudpacking, these coatings prevent O-ring displacement / slippage by increasing surface grip exactly where it’s needed.
This increases sealing reliability, improves assembly consistency, and protects elastomers over time as well.

Beyond friction enhancement, the hardmetal layer also protects the housing itself from abrasion / wear.
This can dramatically extend the housing’s service life – in some cases even creating a lifetime solution for demanding applications.

Both the profile surface and the axial (face) contact areas of the seal groove can be selectively coated, allowing full customization for your application’s geometry and loading conditions.

Additionally, surface textures can be tailored to adjust the friction coefficient, delivering the ideal balance between grip and assembly performance.
