High Density 88/12 Tungsten Carbide Nickel

CT2115-2

CT2115-2 is a Tungsten Carbide Nickel coating applied using the HVOF process. The coating is very dense, very hard, very well bonded and suitable for use in the most aggressive wear environments. CT2115-2 is especially effective in applications where the component is exposed to abrasive media and the coating exhibits more ductility than Tungsten Carbide Cobalt coatings with better resistance to chipping. Use in any acids and alkalais where nickel can be used – avoid nitric acid. Use up to 1000º F.

For the Following Applications:

CT2115-2 is used for severe service conditions of abrasive wear, hard surface wear, low temperature erosion and fretting. Typical components coated with this coating are broke tank beaters, brine pumps, mixer blades etc.

Finishing

Finish CT2115-2 by diamond grinding. Flood cool with 2% oil solution. For roughing use 150 grit diamond wheels, work rotation should be 400 SFPM, .080” per pass crossfeed, .0005” per pass infeed. Finish with 400 grit diamond wheels, work rotation should be 400 SFPM, .040” per pass crossfeed, .0005” per pass infeed.Finishes of 2-4 Ra are possible by grinding. This coating may also be

Finishes of 2-4 Ra are possible by grinding. This coating may also be super-finished to a 1 Ra finish.
