“…One of the new market requirements in the design of body panels for vehicles and various other industries is the development of sheet metal forming technologies that can optimize the performance of the panels. In this respect, deep drawing process of a sheet metal is widely used in the automotive industry (Guillon et al, 2001;Wiklunda et al, 2004). Resistance to friction is one of the main factors limiting the sheet metal forming process (Darendeiler et al, 2002).…”

“…Among others, the most often used test methods are the strip drawing test, drawbead simulator friction test and bending under tension test. Strip drawing test is one of these techniques and allows different tool geometry configurations: flat/flat, flat/ cylinder and cylinder/cylinder (Guillon et al, 2001;Roizard et al, 2009). In this test, the macroscopic coefficient of friction is easily measured and usually used to characterise the lubricated contact between tool and metal sheet.…”

In this paper the results of experimental tests aimed to determine the friction coefficient in sheet metal forming operations for various sheet metal materials and at different operative conditions are presented. The research has considered the frictional characterization of three kinds of drawing quality steels that are commonly used in automotive industry. These are a drawing quality steel (DQ), a deep drawing quality steel (DDQ), and extra deep drawing quality steel (EDDQ). For measurement of the sheet surface topography, a 3D stylus instrument Alicona InfiniteFocus was used. To determine the friction coefficient three tribological tests, i.e. a strip drawing test, a draw bead test and a pin-on-disc tribometer, have been conducted. The experimental results have ascertained several relationships showing the effect of sheet metal surface roughness, lubricant conditions and sheet orientation on the value of friction coefficient in sheet metal forming processes. The results further showed that the surface topography and sample orientation in the rolling direction of the sheet are significant factors that influence the friction coefficient. It was found that the tested steel sheets, selected from automotive industry applications, exhibit anisotropic resistance to the friction corresponding to the measured orientation in relation to the rolling direction of the sheet.

“…(2) No aluminum transfer occurred from the VE and DVE lubricated AA5083 surfaces to the AISI 52100 steel proving that metal-to-metal contact was prevented during the friction experiments by using either of the lubricant types, even though the applied stress during the tests was an order of magnitude higher than the average compressive stress applied during hot forming. (3) Enamel transfer to the counterface may be responsible for controlling the COF.…”

The adhesion of aluminum to tool surfaces during the hot forming of sheet aluminum alloys presents challenging tribological problems. Graphite and boron nitride are commonly used as aluminum adhesion mitigating solid lubricants for hot forming processes, but lubricant breakdown in high-stress areas, such as corners and bends, remains an issue compromising the quality of the formed parts as well as the tool life. Low-melting temperature enamels may provide an affordable and easy to apply alternative. In this study, vitreous (amorphous glass) and devitrifying (two phase crystalline glass) layers were deposited on the surface of sheet aluminum samples with a sedimentation technique. Enamel lubrication was effective in preventing aluminum transfer to the steel counterface. Hence, the prospect exists for the use of these enamels as aluminum workpiece lubricants in hot forming operations.
