“…where W (T ) is the temperature-dependent wear depth; K(T ), the wear coefficient, P , the pressure; and H (T ), the temperature-dependent hardness of the 22MnB5 steel as measured by Hernandez et al [10] through a specially developed hot hardness tester. Gupta [6] developed a generalised wear model that accounted for mechanical as well as several thermally activated processes leading to wear; the temperature-dependent wear coefficient was derived by fitting the model to actual experimental data.…”

“…Mozgovoy et al [15] have studied the tribological behaviour of an uncoated contact pair through reciprocating tests with more test temperatures in the range from 40 • C to 800 • C. The results have shown that the formation of compacted wear debris layers on the surfaces was a main reason when the friction and the wear rate decreased at high temperatures. Hernandez et al [10] has studied the wear mechanisms at elevated temperatures with a High Temperature Continuous Abrasion Tester. Microploughing and microfatigue were the main wear mechanisms of the used tool steel and the wear rate kept relatively stable from room temperature to 400 • C. At 500 • C and 600 • C, as the tool steel became softer, the embedded wear particles increased and penetrated deeper on the tool surface.…”

Numerical study of contact conditions in press hardening for tool wear simulation

In the press hardening industry, industrial and academic efforts are being directed toward predicting tool wear to realize an economical manufacturing process. Tool wear in press hardening is a tribological response to contact conditions such as pressure and sliding motion. However, these contact conditions are difficult to measure in-situ. Furthermore, press hardening involves high temperatures, and this increases the complexity of the tribo system. The present work investigated the contact conditions of press hardening with a commercial FE code (LS-DYNA) as a base for tool wear simulation. A press hardening experiment was established in industrial environments and evaluated through FE simulations. The numerical model was set up so as to approximate the manufacturing conditions as closely as possible, and the sensitivity with respect to the friction coefficients was examined. The influence of numerical factors such as the penalty value and mesh size on the contact conditions is discussed. The implementation of a modified Archard's wear model in the FE simulation proved the possibility of tool wear simulation in press hardening. Finally, a comparison between the tool wear simulation and the measured wear depth is presented.

“…It is common in the industry, for materials to be subjected to processes involving abrasive wear, which causes damage to elements in service use and depending on their application, the material shows greater surface degradation due to the constant friction between abrasive particles (high hardness) or contaminants against the surface of the material, producing its removal and causing considerable deterioration in useful components over time [4,5]. For engineered materials, ironbased alloys are most commonly used in applications involving abrasive wear conditions (e.g., D-type tool steels, manganese austenitic steels and high chromium alloyed castings).…”

This research paper has as main objective to test the effect of thermal cycling on 2904 Oscar Fabián Higuera Cobos et al. the abrasive wear behaviour of the MOLDMAX HH alloy (UNS C17200). The material was subjected to variations in solubilisation temperature of 750 °C, 800 °C and 850 °C for 1 h and aging times at 300 °C of 1 h, 2 h and 3 h. Microstructural and chemical characterization was performed using Scanning Electron Microscopy (SEM-EDS) and Dispersive Energy X-ray Fluorescence (EDXRF), respectively. Abrasive wear behaviour was evaluated under the guidelines of ASTM G65. The results show a significant improvement in the abrasive wear behaviour of the alloy compared to the material in supply condition (T6). The lowest volumetric loss values were obtained from the samples that were subjected to thermal treatment of solubilisation at 850 °C and water cooling with a volumetric loss of 169 mm 3 , in comparison to the supply material with a volumetric loss of 347mm 3 .

“…In these applications, the main failure mechanism of the die is wear, especially high-temperature oxidative wear. This is the predominant wear mechanism for the majority of engineering parts subjected to high temperature ( Ref 1,[5][6][7][8][9][10][11]. Oxidative wear occurs frequently when steel is subjected to high temperature.…”

The friction and wear behaviors of a new hot-work die steel, SDCM-SS, were studied at high temperature under dry air conditions. The wear mechanism and microstructural characteristics of the SDCM-SS steel were also investigated. The results showed that the SDCM-SS steel had greater wear resistance compared with H13 steel; this was owed to its high oxidizability and temper stability. These features facilitate the generation, growth, and maintenance of a tribo-oxide layer at high temperature under relatively stable conditions. The high oxidizability and thermal stability of the SDCM-SS steel originate from its particular alloy design. No chromium is added to the steel; this ensures that the material has high oxidizability, and facilitates the generation of tribo-oxides during the sliding process. Molybdenum, tungsten, and vanadium additions promote the high temper resistance and stability of the steel. Many fine Mo 2 C and VC carbides precipitate during the tempering of SDCM-SS steel. During sliding, these carbides can delay the recovery process and postpone martensitic softening. The high temper stability postpones the transition from mild to severe wear and ensures that conditions of mild oxidative wear are maintained. Mild oxidative wear is the dominant wear mechanism for SDCM-SS steel between 400 and 700°C.
