Cold Spray Additive Manufacture (CSAM)

Where this route may help

Dimensional restoration on a suitable substrate.
Local material build-up or functional layers.
Exploring a near-net component where geometry, access and material combination support the route.

What determines suitability

Cold spray accelerates powder particles to form a deposit through high-velocity impact, without intentionally melting the powder.
Substrate preparation, material pairing, access angle, bond behaviour and post-processing affect suitability.
Deposit properties and interfaces need evidence appropriate to the intended use. A generic material claim cannot qualify the finished part.

What to include in the first brief

Substrate and proposed deposit material, if known.
Surface condition, photographs and repair or build dimensions.
Operating environment and critical mechanical or functional requirements.
Required finish, tolerance, inspection and acceptance criteria.

Evidence is part of the route

Define the material/substrate combination, preparation and spray procedure. Scope coupons or trials where needed, finishing, bond assessment, dimensions and the evidence required by the programme.

A useful starting question

Is cold spray automatically a low-risk repair?

It still needs a technical assessment. Bond integrity, geometry, parent material condition and service requirements determine the evidence and whether the repair is acceptable.

PLANNING YOUR WORK PACKAGE

Cold-spray restoration and additive trials

Bring to the review: Substrate and proposed deposit material, damaged or required geometry, service history and inspection criteria.
What we scope: Partner suitability assessment, agreed trials, finishing requirements and a defined verification plan.
What must be confirmed: Bonding, preparation, geometry access and the intended service must be assessed. A proposed route is not an approved repair.

This capability is supplied through specialist partners. Your quotation identifies the delivery responsibilities and the agreed qualification evidence.
