Anti-seizure / Anti-scuffing
Coating some chemical on material to increase lubrication property in high temperature conditions. It is to anti-seizure and anti-scuffing of material. The seizure or scuffing occur when material is abrasion with another material until high temperature or abrasion in high temperature environment, resulting in reduce strength or ability to withstand the stress of material.
The abrasion material becomes softer and falls off onto another material surface. For example, while bearing rotates, it produce high heat which will reduced surface hardness, causing burns and seizure or scuffing between rollers and running track.
