Potential Methods for Limiting the Consumption of Machine Components Exposed to Abrasive Wear

Autor: VLAD ALEXANDRU FLOREA, RAZVAN ITU

Publikováno v: Sustainability; Volume 14; Issue 19; Pages: 12819

The analysis of the behavior in exploitation of the extraction, transportation and utilization of hard rock type mineral substances proved that one of the most extended and aggressive forms of wear is abrasive wear. The effects of abrasive wear on th
