What is the translation of "pitting" into German?

The term "pitting" in a technical context typically refers to the formation of small depressions or pits on a surface due to corrosion or wear. In this context, "Lochfraß" is the appropriate translation in German, as it specifically describes the singular characteristic of pitting corrosion, wherein small holes or pits develop in materials, commonly metals.

The other options provided do not align with the specific definition of "pitting." "Rissbildung" refers to crack formation, which is not synonymous with the localized corrosion represented by pitting. "Dellen" translates to dents, which can refer to impacts rather than corrosion or wear. "Abnutzung," meaning wear or abrasion, encompasses a broader range of wear processes and does not specifically denote the pitting phenomenon. Hence, "Lochfraß" is the precise term that captures the essence of "pitting" in the context of material degradation due to corrosion.
