OverviewThe CVA 190 L is a compact chemical vapor aluminizing system designed for turbine blades and other high-temperature components requiring aluminide diffusion layers for oxidation and hot-corrosion resistance. It uses a gas-phase chemical process to uniformly treat complex external geometries, internal cooling channels and film-cooling holes. The system features a single reactor, a Φ390 mm work-zone diameter and an adjustable work-zone height of 825–925 mm, making it suitable for smaller components, development batches and production runs that do not require the larger Φ740 × 1000 mm zone of the CVA 440 L.
Key benefits- Compact CVA production capacity matched to smaller turbine blades and hot-section components via a Φ390 mm work zone.
- Treatment of internal and external surfaces, including internal cooling passages and film-cooling holes, using a gas-phase process that reaches non-line-of-sight areas.
- Aluminide diffusion protection that forms a metallurgically bonded aluminide layer to resist high-temperature oxidation and hot corrosion.
- Flexible work-zone height (825–925 mm) to accommodate different component sizes and fixture configurations.
