The GreenSTAMP project is about designing novel, green, high-performance, boundary-film contacts for stamping that satisfy technological and increasingly strict legislative requirements that will reduce greenhouse-gas emissions. This is a critical requirement for stamping and other heavy-loaded lubricated mechanical components because existing European and national regulations has already placed severe restrictions on the use of many of the most effective lubricant additives and so are affecting the performance of some modern machinery.

In this intra-sectorial and interdisciplinary project the two world-leading groups will search for a breakthrough answer: an academic team that has pioneered much of the research in boundary films and boundary lubrication (Laboratory for Tribology and Interface NanoTechnology; TINT); and the R&D team of Hidria corporation, one of the world’s top-4 leading producers of high-quality stamping electrical steel laminations for stacks and EM for the most prominent OEMs in the automotive segment. Hidria, which is among the leading European companies in high-tech sustainable and green technologies, is determined to be the first to introduce novel, advanced, green lubrication in heavy-duty stamping, and so satisfy the stringent environmental regulations and at the same time achieve improved performance.

To match these ambitious goals, novel concepts and methodologies in studying stamping contact interfaces, and scientific breakthrough discoveries in stamping lubrication, are required. The following are the key scientific results expected within the project:

1) a novel, lab-scale, tribological testing and methodology will be designed based on detailed wear-mechanism mapping, able to mimic real-scale stamping that is fully missing today,

2) several different base-fluid types will be systematically studied to reveal the lubricity and viscosity load-carrying requirements for stamping, which could have immense consequences for future green stamping technology and change the stamping lubrication concepts,

3) detailed nano-scale tribochemical and nano-mechanical properties of the nanoscale (< 100 nm thick) boundary surface films from green stamping lubricants will be systematically analysed to reveal the lubricating mechanisms driving their performance,

4) individual effects and contributions of several green additives will be determined; this will serve as a reference database for new innovative green lubrication concepts,

5) new multi-functional additives will be investigated to simultaneously obtain effective tribofilm formation and wetting on steel and coated sheets – relevant for lubrication and post-process cleaning,

6) efficiency of new green lubrication technology in a real-scale industrial stamping process will be determined and verified, a world-first relevant reference, establishing new practice in green-lubrication stamping technology.
