“…The nitrogen intensity in the CrN tool without radical nitride peaked at the outer surface and abruptly decreased to an average value, whereas the intensity in the CrN and TiN radical nitrided tools peaked at the outer surface and gradually decreased with depth until the average value was reached. As reported from previous works [15,18,19], the hardness of the nitride diffusion zone increased proportionally with nitrogen concentration. Then the hardness of nitride substrate decreased continually from the surface to the core when considering from EPMA patterns in Fig.…”

“…Cold forming tools are subjected to severe tribological stresses due to high contact pressures arising via sliding contact between the die and the sheet materials. is results in high frictional heat generation, which affects both the bulk material and wear properties of the tool steel [1]. Since hot stamping tools are subjected to high temperatures, the wear of tool steels and the prevailing wear mechanisms have been studied in detail [2,3].…”

e aim of this work is to investigate the durability of tool steels for hot stamping by comparing the wear resistance of three hot work tool steels. Friction and wear behaviours of different tool steels sliding against a 22MnB5 uncoated steel at elevated temperatures were investigated using a high-temperature version of the Optimol SRV reciprocating friction and wear tester at temperatures of 40 and 200°C. Our results show that friction decreased with increasing temperature, whereas wear of the tool steel increased with temperature for the second and the third tested tool steels. e slightly better wear behaviour of steel specimen 1 comes from the hardness of the carbides in the martensitic microstructure, which are rich in vanadium.

“…A new slider type of test system has been developed to study the performance of several alternative die materials sliding against the advanced HSS [7] and to evaluate the performance of several kinds of coatings and lubricants [8]. Twist compression test (TCT) [9], ball-on-disk test [10], SOFS tribometer (disc-shaped tools sliding against a teal sheet surface) test [11] and deep drawing test [12], ironing test [13], a tensile strip test [14] have been used to investigate the galling in forming the HSS.…”

In order to investigate the friction and wear behavior of high strength steel in hot stamping process, a hot strip drawing tribo-simulator is developed and the friction coefficient, which is an important parameter in the finite element modeling, is measured. The results have shown that the friction coefficient remains almost unchanged until temperature reaches 500°C. It then increases sharply as temperature is increased from 500 to 600°C. It has also been shown that the friction coefficient decreases as the drawing speed increases. The change in the dominate wear mechanism as the temperature and the drawing speed increases has been identified from SEM analyses of the worn surface. The dominate wear mechanism is the groove cutting at temperatures between room temperature and 500°C, which changes to the adhesive wear at temperatures above 500°C. The main wear mechanism is the adhesive wear at 25 mm/s, which changes to the slight groove cutting at 75 mm/s.
