説明

<p>It is important to clarify the behavior of the hot forging lubricants in order to prolong the die life. Here, we introduce methods of observing the behavior of spray solidification on the die and the behavior of a sliding interface in ironing directly by a tribometer with high-speed camera and observation examples. In order to form an uneven lubricating film, it is necessary to ensure that the spray particles are quickly solidified and not flow on the die. On the other hand, at the case of sliding interface, it was observed that the lubricant melts due to heat, boils with bubbles, eventually disappearing, resulting in cohesion. When the lubricant film is thick, the change is suppressed and low friction is maintained.</p>
