Applications

Corrosion & Damage Repair

Cold spray is highly effective for recovering corroded, eroded and damaged components — with no heat input and no practical limit to the depth of material that can be built up.

Restoring corroded, eroded and damaged components

From deep erosion to cavitation, porosity and worn mould tooling, cold spray rebuilds lost material without adding heat — so components are recovered rather than scrapped, and in some cases repaired while still in service.

Erosion Repair

Deep erosion damage can be repaired, as there is no limit to the depth of material that can be built up using our cold metal spray process.

Cavitation Damage Repair

Pumps, faces, shafts — in fact any surface that needs building up due to cavitation erosion can be repaired and returned to service.

Porosity Repair

Porosity often occurs within castings, new or used. Cold spray is a very effective repair method, and one major advantage is being able to carry out the repair while the component is still in service — even when it still contains fluid.

Mould Tooling Repair

We use cold spray for early intervention on wear and damage to prolong tooling life, and for modifications to injection, extrusion, blow and casting mould tooling across a wide range of applications.

The advantages for corrosion & damage repair

No heat input

Components are rebuilt cold, avoiding distortion and metallurgical change to the base material.

Unlimited build depth

There is no practical limit to how much material can be deposited, so deep damage is recoverable.

Repair in service

Some porosity and leak repairs can be carried out in situ, even with fluid still present.

Extend asset life

Early intervention on wear and corrosion keeps expensive components and tooling working for longer.

Frequently asked questions

How deep a repair can cold spray build up?

There is no practical limit — material can be deposited to whatever depth the repair requires, then machined back to the finished dimension.

Can you repair a part without taking it out of service?

In many cases, yes. Porosity and leak repairs in particular can often be carried out in situ, even when the component still contains fluid.

What kinds of damage can be repaired?

Erosion, cavitation, corrosion, porosity and general wear on pumps, shafts, faces, castings and mould tooling are all routinely repaired.

Will the repair change the surrounding metal?

No. Because there is no heat input, there is no heat-affected zone or metallurgical change to the parent material.
