Aluminum Silicon – Polymer powders produce abradable
coatings for clearance control applications where the rotating
component may come into contact with the coating as a result of design intent or operational surges. The coatings are
designed to minimize the wear to the rotating components
while maximizing gas path efficiency by providing clearance
control in seal areas.
The powders produce coatings with excellent rub characteristics. They provide the optimum balance between the desired
properties of abradability, erosion resistance and hardness.
Metco 601NS-1 is offered as an interchangeable product to
Metco 601NS. Based on in-house sprayability and abradablity testing comparing the two products, Metco 601NS-1
exhibits identical processing and service properties to those
of Metco 601NS. Metco 601NS-1 utilizes a secondary
source of polyester which ensures availability through an additional source of supply
Typical Uses and Applications:
Applications include lightweight clearance control coatings for:
- Aerospace turbine engine low pressure compressor
- Automotive and industrial turbochargers
