“…The friction coefficient measured by the Pin-On disc test decreased from 0.78 to 0.495 when the load increased. Sresommroeg reached almost the same value for TiCN-MP coating, and it is 1/3 lower when measured for hardened tool steel [35]. The thickness of the coating was 2.51 µm and the average value of the indentation microhardness H IT was 54 GPa.…”

“…2.4 GPa) there is a huge difference. Sresommroeg experimentally confirmed the lower specific wear rate for TiCN coating via a ball-on disk test against cold rolled carbon steel [35]. Bull also found out that the carbon content is essential for maximizing the coating life and that the microhardness of coating mirrors the wear performance of PVD TiCN coatings in the ball-on-disc test [40].…”

This paper researches the surface condition and wear on the hole-flanging punch when producing a flanged Ø7 mm hole in a steel strip S355J2 + N (1.0577) with a thickness of 3 mm. The hole was flanged by a punch with a defined geometry known as a tangent ogive and described via a caliber radius head (CRH) ratio. During the process, wear of the punch made of hardened tool steel 1.3343 appeared after 20,000 strokes. Thus, a multipurpose coating TiCN-MP deposited via Lateral Rotating Arc-Cathode technology was applied on the punch to extend the punch lifetime. The coated punch was polished to remove droplets after deposition process. By applying TiCN-MP coating, 120,000 strokes were applied to reach the same wear as for the uncoated tool steel. The surface of the punch made of the hardened tool steel for uncoated and PVD coated conditions was researched by scanning electron microscopy after wear, and an energy dispersive X-ray (EDX) analysis was done to identify components of bonded material. In addition, the normal pressure on the punch active surface was studied via a numerical simulation of the hole-flanging process. The position of the high normal pressure is well correlated to the position of the adhesive wear for the uncoated and coated punches.

“…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. However, all of the experiments mentioned above are performed at the room temperature.…”

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.

“…A TiCN PVD coating was effective in reducing galling in the forming of galvanized AHSS grade DP 980Gl [12]. However, nitriding combined with a CrN film coated showed better performance when forming HSS grade SPFH 590 than TiCN PVD film and DLC film [13].…”
