Peening Impressions (Dents)

摘要

The SAE specification J2277 on coverage mentions "overlapping peening impressions (dents)." That specification also includes "Coverage is defined as the percentage of a surface that has been impacted at least once by the peening media." The only evidence that a surface has been impacted is the peening impressions (dents) left by the impacts. It is therefore somewhat surprising that there is no corresponding definition of a peening impression (dent).
