surface engineering
iron based alloysLSN Diffusion manufactures a comprehensive range of iron based alloy powders.
A liquid stream of molten alloy is impinged with a gas or water jet and collected for final processing to size. Some powder characteristics are controlled by the chosen atomizing process.
Iron based surfacing alloys suitable in dry wear service conditions.
LSN Diffusion iron based powder alloys are applied using plasma spray, HVOF/HVAF (high velocity oxy/air-fuel), laser or PTA (plasma transferred arc) surfacing techniques. Self-fluxing thermal spray grades are also available.
LSN Diffusion offers an alloy powder development service (under confidentiality agreement where required) and can manufacture small quantities for customers' R&D projects.

Atomized powder size distribution
LSN Diffusion processes atomized powder by a combination of air classification and sieving to produce the powder Particle Size Distribution (PSD) to suit the surfacing equipment or brazing application deployed by the customer.
In-line and final Quality Control checks use test sieves and laser diffraction analysis equipment to ensure strict conformance to specification.
LSN Diffusion offers a range of standard PSDs coded to indicate the suitable method of application and equipment.
