“…However, the low open circuit potentials of the deformed specimens (Figs. [2][3][4][5] indicate that a Zn coating sufficiently protects steel substrate, even under these severely deformed conditions. This is possible because of the fact that the Zn !…”

“…Sacco et al, who carried out polarization resistance studies of uniaxially deformed galvanized steel, observed a slight increase in the corrosion rate of zinc with an increase in the degree of deformation [4]. Also, a few research groups have studied the forming behavior of coated steel sheets [5][6][7]. But, their main attention is predominantly to understand the effect of coating type, coating thickness, etc.…”

“…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.

In this sense, from polarization resistance studies of uniaxally deformed galvanized steel, a slight increase of the zinc corrosion rate occurs as a function of the deformation degree 17 .…”

Hot-dip galvanized steel sheets with different spangle sizes were deformed by means of rolling and tension. The change of preferential crystallographic orientation and of superficial characteristics due to the deformation was analyzed by means of both X-rays diffraction and optical and scanning electronic microscopy. A correlation between such changes and the involving deformation modes was intended to be done and the spangle size influence on these modes was studied. Coating reactivity change due to the deformation was investigated by means of quasi-steady DC electrochemical tests. The results allow to infer that, in great spangle samples, the main deformation mechanism is twinning whereas in small spangle ones, pyramidal slip systems happen as well. The increase of the reactivity with the deformation is greater in tension than in rolling and it is more important in small than in great spangle samples.
