Current development of high strength abrasion resistant steels is mostly oriented on high hardness, martensitic concept following the hypothesis that the abrasion resistance holds a proportional tendency with hardness. The various experimental observations have suggested that the high hardness of martenzite does not guarantee a high abrasion resistance because the brittle nature of martensite can lead to decrease their abrasive wear. The aim of this work was to analyse the influence of microstructure on abrasion resistance of selected high-strength low-alloyed steels used in the industry. The abrasive wear resistance of selected steels was obtained using an ASTM-G65 three-body abrasive wear test, microstructure and wear resistance determination. It was observed that grain refinement is an effective way of enhancing the abrasion resistance. In this context, micro alloyed steels offer an attractive combination of price and performance.

Effective Compound

The article presents the results of the comparative tribological study of the resistance of multicomponent polyoxymethylene (POM) composites to abrasive wear. The fillers for the studied POM matrix composites were a PTFE powder, the bronze powder, chopped glass fibre, and glass microballs, which were used both individually and in various combinations. Quantities of the composites were developed based on the simplex plan of the experiment. For the research, a Tester T-07 was used as a test stand. The study was conducted in the presence of loose abrasive, electrocorundum F90, subjected to the same conditions of friction for all the tested composites. The study has shown that the most effective compound in increasing resistance to the abrasive wear of the POM composites is the powder of bronze and the hybrid glass filler; whereas, the PTFE powder caused a slight reduction in the resistance to abrasive wear. In order to explain the mechanism of the abrasive wear of the studied composites, a microscopic examination of their friction surface before and after friction was conducted. Based on that study, the effect of particular fillers on the abrasive wear resistance of the tested POM composites was determined.

Before And After

The authors attempted at examining the effect of heat treatment on abrasive wear resistance of metal composite castings. Metal matrix composites were made by infiltrating preforms created from unordered short fibers (graphite or silumin) with liquid aluminium alloy AlSi12(b). Thus prepared composites were subject to solution heat treatment at a temperature of 520°C for four hours, then aging at a temperature of 220°C for four hours. Abrasion resistance of the material was tested before and after thermal treatment.
