CO5774 Co 25.5Cr 10.5Ni 7.5W 0.5C Powder

Co 25.5Cr 10.5Ni 7.5W 0.5C Powder Description:

Co 25.5Cr 10.5Ni 7.5W 0.5C Powder is a specialised Cobalt alloy containing Molybdenum, Chromium, and Silicon. This alloy is characterised by the formation of hard precipitates, particularly intermetallic Laves phases based on Cobalt-Molybdenum-Silicon, which are distributed in a softer Cobalt matrix. These unique properties confer exceptional resistance to corrosion and oxidation, excellent wear resistance, and a high operating temperature with good hot hardness. Notably, coatings made from this powder exhibit a low coefficient of friction, making them suitable for applications where minimal or no lubrication is required. Coatings are typically applied using atmospheric plasma spraying or combustion powder spraying methods and can subsequently be annealed at high temperatures to further enhance their properties. These coatings can withstand oxidation under atmospheric conditions at temperatures up to 760 °C.

Co 25.5Cr 10.5Ni 7.5W 0.5C Powder FAQ:

Q1: What advantages do the Laves phases offer in this alloy?

A1: Laves phases are hard precipitates that enhance the wear resistance of the alloy and contribute to its overall mechanical strength and durability, particularly at high temperatures.

Q2: Can this powder be used in environments with low or no lubrication?

A2: Yes, coatings made from this powder exhibit a low coefficient of friction and are therefore particularly suitable for applications with low or absent lubrication.

Q3: How does the performance of the coating compare to other application methods?

A3: Coatings applied using the HVOF method generally demonstrate higher macrohardness, microhardness, adhesion strength, and deposition efficiency compared to those applied using atmospheric plasma spraying or combustion powder spraying methods.
