Size of delamination of babbit in bearings

I want to compare the different criteria to accept or
reject the size of delamination zones of babbit in
bearings. Any help to find different specifications
will be apreciated.

I had never heard of the term babbit before another one for my downunder dictionary. The Australian Standard 2824-1985 Ultrasonic evaluation of Metal Bearing bonds has both evaluation and classifications of quality. Evaluation dtails the plotting of the poorly bonded areas. Classification has 5 classifications of quality based on both the edge zones and total bearing surface.

I hope this is of some use to you, I have a copy of the relevant pages in a works procedure if you require them for reference.

Re: Process for Bonding of babbit in bearings???
This is fairlu easy process. Using a straight beam probe. The calibration block is important.

Build a calibration block of similiar thicknesses as the component to be examined. Drill a 3/8 inch FBH to the interface of the babbit and the base material.

Establsiha thickness calibration. Determine the back wall single and observe the interface signal. Phase reversal is a good method to detect the calibration reflector.

Scan the componet to be examined. What for the interface signal.

We used this process in the US Navy.

: Make sure a quality flaw detector is available for the task. One with good resolution and RF display.
