High-temperature coatings and repair for rocket propulsion hardware
LACS is a versatile route to manufacture, repair and functionally enhance components used in rocket engines and space-propulsion systems — applying oxidation-, erosion- and thermal-resistant materials only where they are required.
Propulsion hardware runs at the limit of materials
Combustion chambers, nozzle extensions and injectors face extreme heat, oxidation and erosion
Turbopump and thrust-vectoring parts wear and lose dimensional tolerance in service
Refractory and nickel-based alloys are costly and difficult to process
High-value hardware is often scrapped rather than refurbished
Programmes need rapid turnaround on small numbers of critical parts
WHY EXISTING APPROACHES FALL SHORT
Melting-based processes risk oxidation, cracking and metallurgical change
Using refractory alloys in bulk drives cost and material waste
Local repair of worn surfaces is difficult without distorting the part
Qualification requires confidence in process stability and repeatability
LACS deposits oxidation-, erosion- and thermal-resistant materials in the solid state — a candidate route for combustion chambers, nozzle extensions, injectors, turbopump parts and thrust-vectoring hardware, and for local repair, dimensional restoration and graded multi-material structures.
What success looks like
Extended component life in high-temperature service
Local repair and restoration of dimensional tolerances
Graded and multi-material structures — refractory alloys only where required
Reduced material waste on high-value hardware
Rapid refurbishment of propulsion components
Material systems relevant to this application
Candidate material systems for rocket-engine and propulsion hardware — high-temperature, oxidation- and erosion-resistant families, applied selectively rather than in bulk.
Nickel superalloys
Hot-section, chamber and injector surfaces needing high-temperature strength and oxidation resistance.
LACS RELEVANCE
Dense nickel-based deposits without melt-induced metallurgical change.
Copper alloys
Regeneratively cooled chamber liners and components where thermal conductivity is critical.
LACS RELEVANCE
Solid-state build-up and local repair without melting the parent material.
Tungsten & tungsten-based composites
Throat, nozzle and thrust-vectoring surfaces exposed to extreme temperature and erosion.
LACS RELEVANCE
Tungsten deposited without melting — a core strength of the LACS process.
Refractory-metal systems
Hot-gas paths and nozzle extensions operating beyond conventional alloy limits.
LACS RELEVANCE
Applied as a functional surface layer rather than in bulk, reducing the use of costly feedstock.
Ceramic-reinforced metal-matrix composites
Erosion- and wear-critical propulsion surfaces needing hardness with metallic toughness.
LACS RELEVANCE
Reinforcing particles retained intact — no dissolution into a melt pool.
Possible engagement routes
These are possible entry points, not required steps. Engagement can start wherever it fits your situation — and move in any direction from there.
