At the core of industrial efficiency, carbon metallurgy defines the boundary between continuous productivity and technical failure. HARDVANES® exclusively integrates EK60 CARBON GRAPHITE grade, a material developed through isostatic pressing processes that overcomes the physical limitations of conventional extruded graphites.

1. Molecular Tribology and "Transfer Film" Dynamics

Dry operation depends on the material's ability to generate its own lubrication. At a molecular level, graphene layers within the EK60 GRAPHITE crystalline structure are held together by weak Van der Waals forces. During the critical run-in phase, the vane releases sub-micron particles that embed into the asperities of the metallic stator (Rz < 1μm).

This process creates a tribologically stable "Transfer Film". Once established, friction no longer occurs between carbon and steel, but between two layers of polished graphite. The result is a dynamic coefficient of friction of μ = 0.069.

2. Advanced Thermodynamics

Adiabatic compression in vacuum pumps generates severe thermal gradients. EK60 GRAPHITE, with an optimized density of 1.75 g/cm³, offers a perfect balance of thermal conductivity. The material withstands temperature fluctuations of ΔT > 200°C without microstructural fracture, ensuring uniform expansion across all axes.
