Inconel 718


CT5125-1 is a nickel-chromium based superalloy coating applied using the plasma process. The coating is very dense, very well bonded and suitable for use as a build up coating in areas where high temperature resistance and corrosion resistance are desirable. CT5125-1 works well in aerospace and land based turbine applications up to 1300° F.

For the Following Applications:

CT5125-1 is used for severe service conditions of high temperature and corrosion. It is used frequently to repair hot section parts of gas turbines.


Finish CT5125-1 by grinding or machining. If machining use C2 or C7 carbide tools, minimum 200 SFPM, light cuts up to .005” per pass and .0015/rev. traverse speeds. CT5125-1 may be ground with green silicon carbide wheels.

Finishes of 4-6 Ra are possible by grinding. This coating may also be superfinished to a 2 Ra finish.


CT-5125-1 meets the following specifications:
