“…In order to tackle the issues related to the coating selection, various coating materials have been investigated. To begin with, nitride-based compounds, such as TiN, ZrN, CrN, and TiAlN, have been suggested as hard coatings for surface modification, surface barriers, or electrodes [25][26][27][28][29][30] ]. In order to combine superior mechanical properties, e.g., hardness and adhesion to the substrate, with enhanced corrosion resistance, new compounds, such as oxynitrides, of the transitional metals with low oxygen content have been developed [31][32][33][34][35] due to their superior chemical stability, notable optical, electronic, and mechanical properties [36][37][38], with superior mechanical properties compared to those reported for the oxides [39][40][41][42].…”

The reactive cathodic arc deposition technique was used to produce Ti nitride and oxynitride coatings on 304 stainless steel substrates (SS). Both mono (SS/TiN, SS/TiNO) and bilayer coatings (SS/TiN/TiNO and SS/TiNO/TiN) were investigated in terms of elemental and phase composition, microstructure, grain size, morphology, and roughness. The corrosion behavior in a solution consisting of 0.10 M NaCl + 1.96 M H2O2 was evaluated, aiming for biomedical applications. The results showed that the coatings were compact, homogeneously deposited on the substrate, and displaying rough surfaces. The XRD analysis indicated that both mono and bilayer coatings showed only cubic phases with (111) and (222) preferred orientations. The highest crystallinity was shown by the SS/TiN coating, as indicated also by the largest grain size of 23.8 nm, which progressively decreased to 16.3 nm for the SS/TiNO monolayer. The oxynitride layers exhibited the best in vitro corrosion resistance either as a monolayer or as a top layer in the bilayer structure, making them a good candidate for implant applications.

“…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.

“…The high strength of sheet materials leads to difficulties in forming operations. A significant volume of research has focused on preventing the spring back and adhesion of AHSS [2][3][4][5] to produce successful parts with acceptable quality and accuracy. The forming of parts is generally combined with piercing or blanking operations.…”

The short service life of tools used to pierce advanced high-strength steel sheet (AHSS) is one of the primary concerns of the automotive industry. A high tool wear rate is expected due to high strength of the sheet to be pierced. This work investigated the effects of tool clearances on the quality of pierced holes, the piercing force, the piercing energy, and tool wear in piercing operations of AHSS and carbon steel sheet. The piercing energy was observed to be the major factor affecting tool wear. The energy was high when using a small tool clearance on AHSS. The tool with large clearance piercing AHSS exhibited a similar degree of wear as that piercing the low carbon sheet. A double shear zone on the cutting edge of AHSS was responsible for the high piercing energy, especially the energy required to push the slug through the die hole and that required for the return stroke, and the high wear rate of the piercing tool with small clearance.
