This paper focuses on the influence of hardmetal reinforcement amount, shape and size on the abrasive wear resistance of composite iron self-fluxing alloy (FeCrSiB) based hardfacings produced by the powder metallurgy (PM) technology. First, the size of the reinforcement (1 – 2.5 mm) was fixed, but its shape (angular or spherical) and amount (0 – 50 vol%) were varied. Then the reinforcement shape (angular) and amount (50 vol%) were kept constant, while its size (0.16 – 0.315 mm fine reinforcement and 1 – 2.5 mm coarse reinforcement) and proportion of fine and coarse reinforcement (all fine, all coarse, half fine-half coarse) were varied. ASTM G65 abrasive rubber wheel wear test was applied to find out the wear resistance of the hardfacings; an unreinforced self-luxing alloy (FeCrSiB) hardfacing was the reference material. Volumetric wear rate was calculated according to the weight loss. Worn surfaces were studied under scanning electron microscope. As a result, an optimal composition of the hardmetal containing Fe-based hardfacings based on the reinforcement amount (vol%), shape (irregular or spherical) and size (fine or coarse) is given.

The present paper is the result of the investigations of the properties and structure of nanocrystalline layers deposited from iron-based nanoalloy on steel S355N substrate by manual metal arc welding method (MMA) compared to selected abrasion-resistant construction materials currently used in industry. The resultant deposit welds were subjected to macro and microscopic metallographic examination. Working properties of obtained nanocrystalline deposits weld compared to currently used materials were evaluated based on the hardness, abrasive wear of metal-to-mineral. The results of deposits weld working properties measurements were compared with property of wear resistant steel HARDOX 400 type used as reference material.

The aim of this paper is to analyse the effect of the pore morphology on microstructural characteristics, mechanical properties and abrasive wear resistance of iron-based alloys subjected to a thermochemical treatment as carburizing in fluidized bed. The starting materials studied in this paper are represented by pre-alloyed iron base powder obtained by powder metallurgy (P/M) route. The powders were produced by water atomization with different particle sizes (< 45, 45-63, 63-100, 100-150, >150 μm). The raw powders have been mixed with 1% zinc stearate as lubricant and uniaxially compacted into cylindrical specimens at room temperature at 600 MPa. The disc dimensions are 8 6 mm. The green compacts were sintered at 1.150 °C for 90 minutes in a laboratory furnnace. After sintering, a thermochemical treatment was applied. The parameters for the carburizinng in fluidized bed are: temperature of 930 °C and time of 45 minutes. The microstructural characterization was carried out using optical microscopy. The porosity of studied samples were analyzed acording to their microstructural characteristics and chemical composition. The mechanical properties and abrasive wear of the sintered and thermochemical treated samples were evaluated. A correlation between porosity, mechanical properties and abrasive wear was established.
