Methodology for lubricant selection in deep drawing steel process for the automotive industry, a new development and validation
Journal Title: Tribologia - Year 2011, Vol 238, Issue 4
Abstract
The following research presents the evaluation of lubricants currently used by the company METALSA and some proposed by the University of Monterrey to be used in the process of chassis manufacturing. METALSA provides a series of lubricants whose use depends on the process that is going to make. Annually, its suppliers will recommend new lubricants to return more efficient procedures. However, for the company, it is difficult to evaluate those products in the factory. If the evaluation is not the quality that they need, it can affect both the tooling and products. In addition, such an assessment would be a loss of time on the production line and would have to assume the expenditure involved in the possibility of ruining a batch of up to one thousand pieces or one expensive tool. Based on the foregoing, our research has developed and validated a methodology for testing the lubricants used in mechanical processes of sheet automotive steel so that one can select the lubricant of better quality without losing time dedicated to production or risk parts or machinery. The methodology consists of choosing tests designed to make use of T-02 four-ball and T-05 block-on-ring tribotesters. The tribotesters provide certain results, but it is necessary to understand the data. The tribotester T-05, for example, indicates the traces of wear, the friction coefficient, and the volume worn. Those results serve to help make the decision of choosing a lubricant for the studied process.<br/><br/>

CHANGES IN THE MICROSTRUCTURE OF IRON BASED ALLOYS DURING TRIBOLOGICAL CONTACT WITH STEEL HEATED TO THE AUSTENITE RANGE
Hot forming of steel (including forging) is most often performed in the austenite region. Because of that, tribological properties of tools used in hot processing should be related to the conditions of their contact with...
