Detonation Tungsten Carbide coating for Motor Rotor Journal where Antifriction bearing is installed

Posted by Srinivasan ( on 03:23:52 27/11/04


I have been dealing with several coating processes for Turbomachinery. For journals, seals areas etc.

We use APS and DE Gun. Here we have a typical requirement where we want to caot the journal of a motor rotor where the Bearing installed is an antifriction bearing. Due to the nature of a application there is a requirement to remove and re-install the bearing every 3 months.

The interference between bearing ID and shaft OD is about 30 microns.

Will Tungsten carbide with de-gun with stand ?

The max thickness I am looking for is 250 Microns on Radius.

Kindly give me you values pinion.

Thanks and best regards,
