Erosion / Wear Protection
Wear & tear in various forms is part of almost all industrial manufacturing processes – day by day. This cannot be avoided – however with the right tools the situation can be significantly improved.
First step is avoiding simple spare-part exchange. Why – because the same part will suffer the same way! The use of spares is fighting the results only – but not avoiding the real source of the failure, which is the missing resistance! One could say that – regardless of the part – the problem remains the same using spares!
Second step is a principle reinforcement of the part using a synthetic surface treatment to give a superior abrasion resistance – this creating a better long-term performance. Fortunately, this improvement can be realized on new as well as on worn parts!
Erosion / Wear Protection
Technical solutions in detail
Polymer ceramic are self-applicable, cold-curing metal substitutes for the reconstruction of worn or damaged components. Like all semi-hard or hard surfaces, they try to deflect destructive energy, i.e. to bounce it off.
The solvent-free and non-toxic material is applied at room temperature and binds completely corrosion-resistant to almost all hard surfaces. After solidification, a metal-like ceramic material is produced with exceptional linear wear resistance and good thermal and electrical insulation properties. The heat resistance under dry conditions is approximately 200 °C (400 °F). With one exception (CXL), the surface can be machined.
However, Polymer ceramic repair ceramics do not develop their strength through hardness like steel, but through an abrasive behavior which levels and polishes the counter surface in such a way that its construction-related wear potential is reduced. The ceramic formulation has a honing, lapping and polishing character! This makes the material more wear-resistant than unalloyed steel – but NOT harder!
Suitable for protection against linear effects such as on guideways or shafts on which the same honable counter surface always acts. But they are less suitable for dynamically abrasive permanent stresses such as on turbines or impact situations where continuously new – and therefore non-honable – solids strike.
