Test samples were made of different types of polymer board materials including RenShape®, Cibatool® and phenolic cotton laminated plastic laminate (TCF). An original methodology based on a grinding experimental set-up of abrasion wear resistance of polymer construction materials was presented. Equations describing relations between material type and wear resistance were presented and discussed. Micro and macro structures were investigated and used in wear resistance prediction.

Test Results

Multilayered composite specimens consisting of Al2O3 / Al2O3+ 3Y-TZP (A/AZ) layers with different compositions and thicknesses were prepared starting from ceramic sheets obtained by tape casting. Residual stresses arisen from mismatch in thermal expansion coefficient during sintering were evaluated using luminescence piezo-spectroscopy. The stress in the superficial A layer was found to be compressive, and its value depended on the ratio between thickness of A and AZ layer. The influence of the superficial compressive stress on the abrasive wear resistance was investigated using microscale ball cratering test; results were correlated with the superficial compressive stress and compared with a specimen of pure unstressed Al2O3 prepared both by lamination and by cold isostatic pressing. Experiments show an improvement of performances in the samples containing compressive residual stress in the surface.

This paper presents the results of tests for the effects of laser hardening on the course and intensity of wear of 38GSA (38MnSi4) and Hardox 600 steels in an abrasive soil mass. The tests were carried out under laboratory conditions, using a “rotating bowl” type machine. Two types of soil, i.e. light and medium, were used as the abrasive mass. Based on the obtained test results, it was found that hardness decreased (in relation to asdelivered condition). The performed laser surface hardening process significantly increased the abrasive wear resistance only for 38GSA (38MnSi4) steel. As regards to Hardox steel, the hardening treatment reduced the abrasive wear resistance index compared to the as-delivered condition of the steel.

Abstract In this study, SAE 1020 steel surfaces were separately alloyed with preplaced high-carbon-ferro-chromium (FeCr), ferro-molybdenum (FeMo) and ferro-titanium (FeTi) powders by using plasma transferred arc (PTA) heat source. By using three different types of shielding gas compositions during the alloying process, the study investigated the effects of modified shielding gas composition on the microstructure, hardness, and abrasive wear resistance of specimens. The most homogenous microstructure and the highest wear resistance was obtained in the gaseous environment which included 3% of H2. Increasing this rate to 5 % in the shielding gaseous composition caused gaps and pores in the microstructure and caused a decrease in the wear resistance. The x-ray examinations of the specimens identified ferro-molybdenum and ferro-titanium solid solutions, ferrit, austenite and martensite phases in their microstructure as the first phase and FeC, Cr7C3, Cr3C2, Fe3C, Fe7C3, MoC and TiC phases as the second phase. As a result, it was concluded that changes in shielding gas composition in surface alloying process affected specimens’ microstructure and abrasive wear properties.

The paper presents the structure and the results of abrasive wear resistance tests of XAR®600, TBL PLUS, and B27 steel. As a result of the tests conducted by means of light and scanning microscopy, it has been proven that these types of steel are characterised by subtle differences in their structures, affecting their strength and performance properties. In the delivered condition, all types of steel are characterised by a fine-grained structure with post-martensitic orientation with insets of carbide phases. The structural type of the discussed steel types disclosed in the course of the research, as well as the results of the conducted spectral analyses of the chemical composition, indicate that their properties are shaped in the course of specialist procedures of thermomechanical rolling. According to the above-mentioned test results, it can be concluded that the analysed steel types were designed in compliance with the canons of materials engineering in relation to low-alloy steel resistant to abrasive wear. Due to this, the obtained results of the structural tests of XAR®600, TBL PLUS, and B27 steel were subjected to verification in the course of abrasive wear resistance tests by means of the “spinning bowl” method. The tests, conducted in real soil masses – loamy sand, light clay, and normal clay, compared with the results of hardness measurements, indicated a strict dependence of abrasive wear resistance ratios as a function of structure and the heat treatment condition of the tested types of steel. All the obtained test results were referred to 38GSA steel in a normalised condition.

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.

The development of energy and resource-saving methods and technologies for strengthening and restoring the working bodies of agricultural machinery will increase their abrasive wear resistance and durability by using materials from machine-building waste and reduce the cost by 10-30 percent without reducing operational characteristics. (Research purpose) The research purpose is in increasing the abrasive wear resistance and durability of cultivator legs by surfacing powder materials obtained by electroerosive dispersion from solid alloy waste by high-frequency currents. (Materials and methods) Authors obtained a powder for research on their own experimental installations of the CCP "Nano-Center" of electroerosive dispersion from waste of sintered hard alloys of the T15K6 brand. The microhardness of powders and coatings on microshifts was measured using the PMT-3 device, and the hardness of coatings with the KMT-1 microhardometer was measured using the Rockwell method according to GOST 9013-59. The microwave-40AV installation was used to assess the wear resistance of materials of working bodies of tillage machines. (Results and discussion) In the course of laboratory wear tests the relative wear resistance of samples hardened by high-frequency surfacing currents significantly exceeds the wear resistance of non-hardened samples made OF 65g steel, accepted as the reference standard. (Conclusions) Based on the results of experimental studies, the article proposes a new resource-saving technological process for strengthening the working bodies of agricultural machinery through the use of materials from machine-building waste, which allows increasing the abrasive wear resistance of working bodies by 1.5-2 times due to the use of tungsten-containing materials.
