Method comments

PG Time: As needed. OP Step: For less relief OP-S can be replaced by OP-U. For Titanium and Titanium alloys: FG Step: For cp Titanium can MD-Largo with DiaPro Allegro/Largo be replaced by MD-Plan with DiaPro Plan. P Step: This step must be removed and instead the OP step is extended, running 2 minutes at a time up to 10 min. OP Step: Mix 90 ml OP-S + 10 ml hydrogen peroxide (30%). See also Application Note on www.Struers.com : "Metallographic preparation of titanium".

This method is developed to fit a standard equipment configuration.

For advice on how to adjust the method to fit your equipment, please take a look at Preparation Parameters.

The preparation time for the plane grinding (PG) step depends very much on the condition of the samples and if they are prepared as single specimens or clamped in a specimen holder. Please check the samples after the first step and repeat it if necessary.
