Testing the Wear Mechanisms of the Components of Machines Used in Fossil Energy Resource Extraction

The paper presents the results of tests wear hardened wear-resistant steels in presence quartz, coal and coal-mineral abrasives a differentiated ratios each component case without abrasives. were carried out on ring-on-ring test stand. Volume loss was parameter used to characterize level. Based Scanning Electron Microscopy (SEM) observations, different mechanisms surface destruction depending type abrasive found. For quartz abrasive, it shown that grains cause micro-cutting, but cracks also appear further transform into shallow holes. In mixtures with coal, micro-scratched by grains, some these hammered surface, what favoured fractions. traces single cutting observed, as well unremoved scratches formed at sample grinding stage. observation, two models steel determined.
