| Abstract Scope |
In the process of cold forging, lubricant is one of the important elements because they contribute to prolong the die life and improve the surface quality of products. On the other hand, it is well known that lubricants are exposed to the very severe condition such as high contact pressure and high temperature induced by processing heat. So that, oil type cold forging lubricants cause oil film shortage and induce processing defect. In order to make a breakthrough in these situations, we find out the possibility of phase transition materials from liquid to solid under high-pressure conditions. In this research, we develop new oil type lubricants for cold forging using phase transition materials. Moreover, we find that these materials show higher lubricating performance for cold forging process compared with the conventional lubricants. These results indicate that phase transition behavior under high-pressure conditions support the lubrication for cold forging process. |
