High Density 75/25 Prealloyed Chrome Carbide Nickel Chrome


CT2302-2 a Prealloyed Chrome Carbide Nickel Chromium applied using the HVOF process. It is a tough, dense coating well suited to applications where both heat resistance and wear resistance are combined. It is often preferred for hot erosion applications such as those found in industrial gas turbines and in other industrial applications where hot hardness, resistance to abrasion, resistance to erosion and resistance to fretting is required. Since chrome carbide coatings are generally lubricious, CT2302-2 may be used as the hard component of a bearing match where galling has been a problem. CT2302-2 may be used up in applications where it will be exposed to temperatures of up to 1500° F.
