“…In addition, soft Zn-Al alloy (ZAS) is often used as a tool material in press trials before mass production. It is well known that the friction coefcient depends not only on the test specimen but also on the tool material [7][8][9][10][11][12][13][14] . Therefore, in industry, these changes in the friction coef cient depending on the tool material cause defects such as cracks, wrinkles and surface distortion, which were not observed in press trials, because the tool materials in mass production are different from these in the press trials.…”

The frictional behavior of galvannealed steel sheets (GA) depending on tool materials was investigated. GA having different ζ/δ 1 phase intensity ratios was prepared as specimens. In addition, lubrication-treated GA was also prepared using these specimens as the base material. Four kinds of tools composed of zinc alloy die casting (ZAS), ductile cast iron (FCD), alloy tool steel (SKD) and Cr-coated FCD (CR) were used as sliding tools in order to simulate actual press tools used in trials and mass production. When the tool material was harder than the test specimens, the friction coef cient of the GA increased as the amount of the ζ phase increased, and the effect of the lubrication treatment was clearly observed. However when the tool material was softer than the test specimens, the friction coef cient was constant and independent of the existence of the ζ phase and lubrication treatment. The change in the frictional behavior was discussed from the viewpoint of the change in the friction mechanism depending on the relative hardness of the surfaces of the specimens to the tool materials.

“…The role of formed transfer film has been shown in contact between aluminum alloy sheets and coated 'high speed steel' (hSS) tools. another steel strip-drawing test has been elaborated by Pesch et al [22]. different hard coatings deposited by CVd, PVd and 'arc' processes have been examined.…”
