Title: (EN) IMPROVED COATING BLADE
(FR) LAME ENDUITE AMELIOREE
Abstract: front page image
(EN)


Improved coating blades are disclosed, as well as processes for manufacturing
such blades. The inventive blades have an intermediate edge deposit (3)
effective to reduce heat transfer from a wear resistant top deposit (2) to the
blade substrate (1) . In one embodiment, the intermediate layer is comprised
of NiCr, possibly with embedded oxide particles. Suitably, the intermediate
layer and the top deposit are applied by an HVOF process. It is also envisaged
that the intermediate layer may be deposited by plasma spraying. The
intermediate layer may comprise stabilized zirconia.
