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.

Effect Of Surface

On the example of Hadfield steel, as the most common material of fast-wearing parts of mining equipment, the effect of surface hardening by plastic deformation on their impact and abrasive wear resistance is considered. Wear test is conducted on magnetic ironstone as typical representative of abrasive and hard rock. As result of wear of initial samples with hardness of ∼200 HB and samples pre-hardened with different intensities to the hardness of 300, 337 and 368 HB, it is found that during the initial testing period, the initial samples pass the “self-cold-work hardening” stage with increase in hardness to ∼250 HB, which remains virtually unchanged during further tests; the hardness of the pre-hardened samples does not change significantly throughout the tests. It is established that the rate of impact-abrasive wear of pre-hardened samples is significantly (up to 1.4 times) lower than the original ones that are not subjected to plastic deformation, and decreases with increasing degree of cold-work hardening. Preliminary surface hardening by plastic deformation can serve as effective way to increase the service life of fast-wearing working parts of mining equipment.
