Abstract Scope A goal of the forging industry is to minimize the amount of conventional lubricants used during forging. To evaluate the impact of substrate conditions of the level of friction developed during forging, a laboratory test, called the ring compression test, has been identified and validated that provides a quantitative measurement of the impact of a range of substrate conditions on the level of friction between a forged aluminum workpiece and an H13 steel forging die. Several forging conditions have been examined at both room and elevated temperatures (100°C and 200°C), including lubricated and un-lubricated, un-coated, nitrided, and a number of PVD coatings. Results from the study will be presented, showing that in the unlubricated condition, the lowest friction factors were obtained with two PVD nanocomposite, thin-film coatings containing lubricious particles such as graphite and/or molybdenum disulfide.
