Case studies

Repairing deep cuts in alloy wheels typically involves welding on more metal to fill the grooves – a hot, slow, and difficult process that requires a skilled technician, and can cause cracking and damage to the heat treatment. Equipped with Titomic’s D523 cold spray system, one leading wheel repairer was able to turn that around.

The team at Fire Island Wind - a remote wind farm in Alaska run by GE Renewable Energy - needed repairs to a wind turbine heat exchanger. Replacing these heat exchangers is a logistical challenge, as they need to be drained, removed, and replaced, requiring hours of labor and costing up to $80,000.

To recondition or repair large fuel tanks, they often need to be taken off a vehicle, drained, made explosion proof, then welded. With cold spray, you can repair fuel tanks and parts in-situ.

Traditionally, restoring worn parts like a bearing housing requires resurfacing via sleeving. This is when a large cylindrical pipe billet is machined to the desired diameter and thickness, and then cooled so it can be forced inside the bearing.
