ITS 1610-T is an intimate combination of 12%
silicon aluminium and high temperature polymer powder developed for
seal clearance control applications.
ITS 1610T Plasma Sprayed Coating
250 �m thick.
The powder is applied to a surface by thermal
spraying. The resulting coating provides a high degree of
"abradability", that is the capability to readily and sacrificially
wear away in the event of contact by a mating rotating part. Under such
"rub" conditions the mating component will normally suffer negligible
loss of material. Coatings are suitable for use in the compressor
section of gas turbines, other compressor applications and the cold
side of turbochargers. Coatings resist erosion by the flow of gases and
are resistant to corrosion, oxidation and other degradation up to
temperatures of 400�C for limited duration and 350�C for extended
service conditions. ITS 1610-T is thermally stable and resistant to
The material has been developed for deposition by
plasma spraying. The coating thickness is determined by factors
associated with the application, typically in the range 0.2 mm to 5.0
The use of silicon aluminium/plastic composite
seal clearance control coatings in the compressor section of aero
engines is well established. Plasma spraying is a proven technology for
the application of such coatings. ITS 1610-T harnesses modern
technology and efficiencies and results in a product with performance
enhancement at minimum cost. Thermal spray processing cost is minimised
by the fact that:
Processing cost is minimised by free flowing
powder enabling high deposition rates at high deposit efficiency.
Relatively thin coatings of the type used on
turbochargers do not require a bond coat.
Fine powder results in a smooth "as sprayed"
surface finish enabling a finish machining operation to be minimised or
Price is typically around half to to two thirds
of the market prices for other SiAl/Plastic materials.
The product is expected to find a market in
established aero gas turbine applications and extend the benefits of
such coatings to other more cost conscious industries such as land
based gas turbines, marine gas turbines, industrial compressors, and
turbochargers for motor vehicle, marine and other applications.
