... , Volume 11 of ASM Handbook . Erosion Erosion can be defined as the removal of surface material by the action of numerous individual impacts of solid or liquid particles. Erosive wear should not be confused with abrasive or sliding wear, because the mechanisms of material removal, and therefore...

... are invariably tempered to avoid impact and impact fatigue failures. Most carbonitrided gears are tempered at 190 to 205 °C (375 to 400°F) to reduce surface brittleness and yet maintain a minimum case hardness of 58 HRC. Alloy steel parts that are to be surface ground are tempered to minimize grinding cracks...

Pin abrasion tests of ADI have shown that the harder grades perform better than austempered steel as well as quenched and tempered steels ( Ref 2 ). Impact erosion tests have shown that ADI, with a BHN of 472, performs better than 12...
