The increasing application of precoated steels to vehicle manufacture and the requirement for greater cost effectiveness, quality and productrivity have highlighted the need for further research into the interactions between tool materials and the types of coated steels used in the automotive industry. The main objectives of the research reported here were: to determine the optimum combination of tool material and coated steel in terms of formability and friction parameters; to interpret the differing performances of these combinations with reference to the intrinsic and surface properties of the materials; to examine the influence of a range of lubrication conditions on the tool/coating interactions; to rank the effects of tool material, steel and lubrication. Formability and friction tests were devised and performed using fur types of coated steel currently used in the European automotive industry. These were zinc and zinc-nickel electro-coated steels, hot-dip galvanized steel and hot-dip galvanized iron-zinc alloy coated steel.
