Cold spray for engine refurbishment. Deposit a vast range of metals with zero heat input.

For metal repairs and restoration

Repairing and restoring metal components can be complex and time consuming – and the right technique can make all the difference.

For decades, engine refurbishment has been limited by traditional methods such as welding, and coating methods that are slow, dangerous, and difficult.

Cold spray offers an alternative. A process which deposits a vast range of metals with exception bond strength at speed. With cold spray, you can put down dense layers of metal to repair and resurface parts without heat and without damage.

Why is cold spray right for engine repair?

More durable, more dense

Produce coatings and repairs with fine-grained microstructures and minimal porosity.

Cold spray also deposits extremely thick coatings, up to 50mm thick to restore and refurbish critical parts.

More options

Use a wider variety of metal alloys and open new possibilities for restoring components previously considered to be beyond repair.

Fuse nickel onto cast iron, aluminium onto steel, and so much more.

More protection

Repair corrosion and provide long-lasting protection, such as in marine applications where grit is used to blast away corrosion and apply corrosion-resistant aluminium to steel structures – without the need for disassembly.

No more damaged parts

Repair delicate or temperature-sensitive components, such as cast iron casings, with minimal heat input, reducing the risk of cracking, annealing, or other damage.

Less wait

Repair obsolete or expensive components in hours – rather than waiting months for replacement parts.

What is cold spray?

While our article What is cold spray? covers this revolutionary method in more detail, here’s a brief snapshot:

Cold spray is a process in which metal powders are accelerated to high speeds using compressed gas, and then impacted onto a substrate. This forces the particles to bond to the substrate, forming a dense, solid coating.

Effective repair & remanufacture of heavy vehicle assets

Often when key components on heavy vehicles are damaged, they’re scrapped or replaced. This is a costly yet entirely avoidable expense.

Learn how our cold spray technology systems make it easy and cost-effective to repair and restore parts – so your operations can keep on moving.

 

MTU Rolls Royce Solutions repairs at V16 engine - running for 24,000 hours since repair.

Titomic cold spray was evaluated on the rebuild and long-life maintenance of a large-scale diesel engine. With numerous repairs made with cold spray, the engine was seen to be operating well after 24,000 hours of operation, with cold spray proving to be a competitive repair solution.

What is welding?

There’s a reason why welding has been a staple of metal repair and restoration for decades. By heating metal parts until sections of them become pliable or molten, it’s easy to mould them together – as well as make joints more precise and controlled. And because welding can join metal parts of any thickness, it’s a versatile way to build a wide range of metal components.

But there’s a catch: welding a large area to repair geometry or surface imperfections can introduce significant heat. This threatens the metal’s grain structure, potentially causing warping, cracking, or heat distortion.

Cold Spray: the right tool for engine refurbishment.

Cold spray:
Produces fine-grained, dense coatings with improved mechanical properties.
Repairs with dissimilar metals, such as aluminium onto steel.
Uses a variety of metal alloys, including high-temperature and reactive materials.
Minimal heat input, reducing the risk of thermal damage.
No need for hot work certification.
Easy to learn and apply with Titomic training.
Doesn’t weld or join separate metal structures.
Welding:
Produces strong, permanent bonds between metal parts.
Produces precise and controlled joints.
Suitable for fabricating large metal structures.
Can generate high levels of heat, potentially damaging the substrate or surrounding areas.
High heat may warp metal parts and change the metal’s grain structure.
Requires hot work certification, specialised equipment and expertise.
