Description

Oerlikon Metco’s CoCr[NiWSi]C products are inert gas atomized powders that are chemically homogeneous, exhibit minimal satellites and are freely flowing. They are designed and provide excellent results for a variety of applications such as laser cladding, thermal spray and PTA. These materials form coatings that are appropriate for wear and corrosion resistance in relatively high-temperature service conditions.


Amdry X40, Metco 45C-NS and Metco 45VF-NS are similar in chemistry to Stellite 31 (Stellite X40) and are designed to be applied using atmospheric plasma spray.


Amdry X40 can also be used as complimentary additive to Oerlikon Metco's ADB brazing alloys to facilitate crack and surface repairs.


The materials Amdry X40, Metco 45C-NS and Metco 45VF-NS of this material family differ primarily in their particle size distribution.

Other

Amdry X40, Metco 45C-NS and Metco 45VF-NS are similar to Stellite 31 (Stellite X40) and are generally applied using atmospheric plasma spray. They have the same elemental composition, but are differentiated by particle size. Coatings are resistant to wear by abrasive grains, hard surfaces, fretting and particle erosion at high temperatures. They are recommended for salvage and build-up applications. The coatings are useful in gas turbine engines at high temperatures up to 850 °C (1550 °F), and for metal working components which require a combination of mechanical integrity and hot wear resistance. Metco 45C-NS can be applied using atmospheric plasma spray or combustion powder spray. It differs from Metco 45VF-NS in that it produces thicker coatings that are softer. The thickness limitation of Metco 45C-NS coatings is 1.8 mm (0.070 in). Thicker coatings may require specialized spray techniques. Metco 45VF-NS is intended to be used for thin coatings, up to a maximum thickness of 0.4 mm (0.015 in). The coatings produced are smoother and harder than coatings produced using Metco 45C-NS and Amdry X40. Amdry X40 can also be used as a complimentary super-alloy filler metal in brazing applications.
