The thicker the O-ring and the greater the quantity of the proper lubricant, the better for corrosion resistance. Proper filtering to prevent entrained abrasive is critical. Surface abrasion damages passivation. Corrosive...

.... The entire surface of the die was covered with fatigue cracks and many fillets had been plastically deformed. Several other types of damage were also observed, including areas of oxidation, corrosion pits, voids, abrasive wear, die adhesion, and thermal fatigue. Fatigue cracking was the primary cause...

.... Hacksawed, bandsawed, or other rough surfaces usually require abrasive grit sizes in the range of 120- to 180-grit (P120 to P180). Grinding must remove the damage created by sectioning ( Fig. 16 ). If the initial grinding step does not remove this layer, the plane of polish may be within the zone of surface...
