abrade

The thermal spray cell enables Vector Aerospace to apply a full range of coatings including, metallic bond coats, repair materials, ceramics and abradables. The cell primarily incorporates the Metallisation PS50M mass flow controlled plasma system and the Metallisation ARC 140/5250 automatic system.

An overview of compressor abradable thermal sprays, in: c.c.

Each rotor is extruded from aluminum bar stock and cut to length before a proprietary abradable powder coating is added.

For example, a new generation of abradable thermal spray powders was introduced for industrial gas and steam turbine customers, providing improved engine efficiency, safety and performance.

Figure 4 shows the abradable material which allows operation at very small tip gaps without damaging the rotor.
