Laser clad layer Ultimet
Topclad’s Ultimet layer is a cobalt-based alloy applied through precision laser cladding. This metallurgically bonded coating offers a balance of toughness, wear resistance, and corrosion protection—ideal for components operating under severe mechanical and chemical exposure.
Ultimet – cobalt-based laser clad layer for extreme wear and corrosion
Ultimet is a cobalt-chromium-molybdenum-nickel alloy designed for use in harsh environments where conventional coatings fall short. Ultimet resists wear, impact and chemical attack, making it highly suitable for dynamic, high-load or corrosive conditions. The layer is provided with a laser clad layer, enabling exact thickness control and metallurgical bond with the base material.
Benefits of Ultimet
- No delamination
The metallurgical bond ensures the layer won’t chip or flake off. - Built for the demanding conditions
Ultimet performs reliably in corrosive and high-impact environments, making it ideal for components exposed to aggressive media and mechanical shock. - High ductility
Absorbs dynamic loads and prevents cracking under stress. - Thermal shock resistant
Maintains integrity under rapid temperature changes. - High temperature operation
Suitable for applications up to 900°C.
Advantages over traditional coatings
- Tough and impact-resistant – Unlike brittle coatings such as HVOF or ceramics, this layer can absorb shocks and localized stress.
- High corrosion resistance – Particularly effective in chloride-rich and acidic environments.
- Recladding possible – The layer can be restored multiple times without replacing the base material.
- No delamination – The metallurgical bond ensures the layer won’t chip or flake off.
- Precision repairs – Laser cladding allows highly targeted repairs and fine control over layer thickness.
Applications
Ultimet is typically used in shafts, hydraulic cylinders, rollers and high value machine components that face above average mechanical wear or chemical exposure. It is ideal for both original equipment and repair of high-value parts that must maintain integrity under stress.

Why cobalt-based layers make the difference
Compared to traditional coatings like hard chrome, HVOF or nickel-based alloys, cobalt-based layers provide superior toughness and impact resistance. They maintain their protective properties even when subjected to high point loads or cyclic stresses, and resist cracking, chipping, or corrosion in conditions that degrade most alternatives.
