【Q&A】Why do seizure and stiffness occur at high temperatures? 【Part 2】

エムアンドエム エムアンドエム
In die-cast molds and movable parts used in high-temperature environments, issues such as "despite applying grease, movement becomes sluggish" and "eventually seizing occurs" can be observed. This phenomenon is not merely due to wear or insufficient lubrication; the main cause is the inability to maintain a lubricating film at high temperatures. As the temperature rises, the separation and volatilization of oil components progress, making it easier for metal parts to come into direct contact with each other, leading to increased friction and rising sliding resistance. Seizing does not occur suddenly; it is a phenomenon that surfaces as a result of the gradual deterioration of lubrication conditions. In high-temperature environments, it is not only the "heat resistance temperature value" that matters, but also whether lubrication conditions can be maintained at high temperatures, which becomes an important point in grease selection. The mechanisms behind seizing and sluggish movement, as well as considerations during selection, are organized technically in the attached materials.
