“…The decrease in wear loss with increasing heat treatment temperature up to 400°C is due to precipitation of Ni 3 P, which is confirmed by XRD measurement (see Figs. [6][7]. For the coatings heat-treated at 400°C, an increase in the amount of wear is expected with the increase in friction coefficient.…”

“…Most of these parts are made by powder metallurgy technique and are required to exhibit good wear resistance [2]. In order to improve wear behavior of iron based powder metal components, reinforcing with hard particles [3][4][5], alloying [6,7], heat [6,8] and surface treatment (e.g. steam oxidation [9,10], boronizing [10][11][12], shot peening [11,12], carbo-nitriding [10] and plasma-nitriding [13]) are often carried out.…”

“…The abrasive wear loss has been reported to decrease with increase in the volume fraction of martensite. It has also been reported that the hardness of martensite has a greater influence on the abrasive wear resistance of steels than its volume fraction [7][8][9]. The martensitic microstructure with carbides exhibited better wear resistance as compared to bainitic or pearlitic microstructures [10].…”

“…In addition, the roles of the residual porosity and of the presence of copper as a solid lubricant are pronounced in this investigation. Tekeli et al [3] studied dry sliding wear behaviour of Fe-0.3%C-2%Ni powder metallurgy processed (P/M) steels at constant sliding speed, load and distance. One of the sintered specimens was quenched-tempered and others intercritically annealed.…”

Powder Metallurgy (P/M) is an established manufacturing process allows components of complex geometries with tailor-made strength and high tolerances to be produced in one single operation without subsequent machining resulting in low cost and low environmental impact. Thus, it has replaced all traditional methods of metal forming operations because of added advantages like lesser energy consumption, maximum material utilization, low relative material wastage, and competitive cost. Sintered low alloy steels find numerous applications in making components for machine parts, automobile parts, structural components, etc. Properties and microstructures obtained using P/M that can't be obtained by alternative metal working techniques. The final density of the sintered P/M parts plays a vital role in determining the component properties and characteristics. In the present study, an attempt has been made to investigate the dry sliding wear characteristics of sintered/hot extruded P/M alloy steels with Fe-1% C as base material, W (Tungsten) and Ti (Titanium) as alloying elements. The wear behavior of the sintered/hot extruded performs were studied under dry sliding conditions on pin-on-disc (ASTM G99) arrangement against EN 38 steel disc of hardness HRC 60 with a constant sliding speed of 2m/s and at a normal load of 30, 50 and 70N respectively. The microstructure and wear regime of extruded P/M steels has been systematically characterized to understand the structure-property relationships using both optical microscopy and scanning electron microscope (SEM). Addition of W and Ti significantly enhances the wear resistance of the extruded P/M plain carbon alloy steel due to the presence of WC (tungsten carbide) and TiC (titanium carbide). The microstructure reveals a combination of Widmanstatten type ferrite on both the extruded P/M steels. Coefficient of friction is slightly higher due to presence of second phase hard WC in tungsten alloyed plain carbon steel. Delaminative wear mechanism is commonly found in both extruded P/M steels with an increase in applied load.
