“…The peak in erosion rate occurred at impingement angle of depending upon the alloy and the erodent particle hardness. Although the erosion rate decreased with increase of volume fraction of carbide particle [100], Sapate and Rao noted that the dependence of erosion rate on carbide volume fraction was a strong function of erodent hardness [101]. Large volume fraction of carbides proved beneficial to the erosion resistance with softer erodent particles.…”

Weld overlay coatings also known as hardfacing is a method which involves solidification for applied coatings. This method is as old as welding process and was first applied by J.W. Spencer in 1896. This technique offers unique advantages over other processes in that the overlay/substrate weld provides a metallurgical bond which is not susceptible to spallation and can easily be applied free of porosity and other defects. Weld deposits can have a thickness as high as 10 mm. Hardfacing process can be carried out easily even in on site. The process is also extremely versatile as a large variety of materials can be deposited for protection against degradation.Weld overlay coatings can be classified under four different categories. These are (1) surface cladding where a thick layer of materials is applied and the overlay layer can have completely different composition from the substrate, (2) hardfacing where a materials more resistant to degradation is applied with good metallurgical bonding and the composition can be close in terms of composition to that of the substrate, (3) build up where a weld deposit is applied to restore the original dimension of the component and the composition of the build layer is exactly similar to that of the substrate and (4) buttering where an intermediate layer is deposited before applying the final coating.The materials used for hardfacing should have melting point close to or lower than the substrate materials. During hardfacing, the temperature of the coating

“…Hardfacing procedure can be used for the production of new overlays as well as for restoration of worn surfaces [2,3]. Different types of welding, brazing, powder metallurgy (liquid phase sintering), laser-cladding, thermal spraying, etc., are widely used for the production of hardfacings [4].…”

Composite hardfacings produced by Plasma Transferred Arc Welding (PTAW) and Submerged Arc Welding (SAW) possess a good combination of hardness, wear resistance and fracture toughness, thus providing high wear resistance. Although they cannot substitute and be compared with conventional WC-Co based hardmetals, still they can be used in many applications where high wear resistance, hardness and toughness are in great demand. In this study two different hardfacing production technologies PTAW and SAW, were used to produce the hardfacings for abrasive wear conditions. In both cases hardfacings were welded on the top of low alloy steel using different proportions of disintegrator milled hardmetal WC-Co powder of different fractions as a reinforcement and self-fluxing alloy as a matrix. They were analysed in regard to Rockwell and Vickers hardness, wear behaviour, and microstructural analysis. SAW hardfacings were subjected to Rockwell hardness test after process and after two cycles of tempering; secondary hardness effect was detected as increment of hardness values from 39 HRC to 58 HRC after first cycle of tempering. High Vickers hardness values did not correlate with wear results, as it commonly shows hardness of hardmetal particles. Dissolution of hardmetal particles in the matrix was observed in both PTAW and SAW hardfacings with higher amount in the later. This amount correlated with heat input during welding process. Wear test results in abrasive emery wear (AEMW) and abrasive wheel wear test (AWW) showed almost analogous tendency, with slightly lower wear in later. Both types of hardfacings have shown promising results in intensive wear conditions.
