“…Similarly, various researchers studied the influence of alloying elements on the wear and friction of Fe-Cu-C-based composites and the research suggests that the addition of elements such as Mo, Cr, Al and W alter the mechanical and frictional properties of the composites. 14,15 In a recent study by Kannan et al 16 the authors suggested the role of various phases developed in powder metallurgical process in the determining the mechanical and tribological response of the composites.…”

In this work, Fe-2Cu-0.8C-CaF2 self-lubricating composites with calcium fluoride solid lubricant (3 □ 12 wt.%) were examined for their friction and wear at 5 and 10 m/s, at 500 °C. Addition of CaF2 decreased density and hardness of composites. During sliding, materials gained weight due to oxidation. Compared to the base matrix (Fe-2Cu-0.8C), composites showed lower weight gain and lower coefficient of friction. Increase in porosity with CaF2 content increased oxidation resulting in higher weight gain and increased friction due to wear debris abrasion. Increase in speed reduced weight gain due to higher material loss. Adhesion was the dominant wear mechanism in base matrix; delamination and wear debris abrasion in composites. Temperature rise at sliding surfaces was theoretically estimated. Increase in speed increased temperature, which reduced friction due to softening and shearing of solid lubricant. Composite with 3 wt.% CaF2 showed least surface damage and 6 wt.% showed lowest coefficient of friction, i.e., lower by 16% and 10% at 5, 10 m/s than base matrix. Tribological response of the composites to a broad range of applied parameters, viz. speed, load and temperature taken from earlier works and present work is briefly summarized. The study suggests the dominant role of CaF2 content and the wear debris in altering the tribological response. Further, the stability of the developed composites at high temperature and high load conditions was also established. The study suggests that the developed composites could serve high-load and high-temperature applications for heavy machinery such as bearings, shafts and gears.

Efficient Wear Simulation Methodology for Predicting Nonlinear Wear Behavior of Tools in Sheet Metal Forming

et al. 2022

In conventional wear simulation, the geometry must be updated for succeeding iterations to predict the accumulated wear. However, repeating this procedure up to the desired iteration is rather time consuming. Thus, a wear simulation process capable of reasonable quantitative wear prediction in reduced computational time is needed. This study aimed to develop an efficient wear simulation method to predict quantitative wear reasonably in reduced computational time without updating the geometry for succeeding iterations. The wear resistance of a stamping tool was quantitatively evaluated for different punch shapes (R3.0 and R5.5) and coating conditions (physical vapor deposition of CrN and AlTiCrN coatings) by using a progressive die set. To capture the nonlinear wear behavior with respect to strokes, a nonlinear equation from a modified form of Archard’s wear model was proposed. By utilizing the scale factor representing the changes in wear properties with respect to wear depth as input, the simulation can predict the behavior of rapidly increasing wear depth with respect to strokes after failure initiation. Furthermore, the proposed simulation method is efficient in terms of computational time because it does not need to perform geometry updates.

Homogenization of 3wt% Molybdenum addition in Fe-0.7C alloy in the presence of 2wt% Cu under sinter-forged condition has been carried out. Samples alloys have been fabricated by sinter-forging route using elemental powders. Sintering was carried out at 1150oC in N2-10%H2 atmosphere. The sintered samples were immediately forged using 100-ton friction screw forging press at the sintering temperature. Homogenization studies were carried out in two steps, the preliminary study was carried out on a press-sinter-forged compact while the final study was carried out on sinter-forged slab prepared by capsule forging. Homogenization temperature was kept at 1250oC (heating rate of 10oC / min) in flowing N2-10%H2 atmosphere for various durations between 1-5 hr. The extent of Mo and Cu dissolution in the Fe matrix of homogenized samples was ascertained using microstructural characterization under optical microscope, SEM and EDS analysis. The influence of initial powder particle size, sintering tempera ture and homogenization temperature & duration on homogenization behavior have been discussed in length.
