Vulcanization Of Powder Metallurgy Gears
Apr 18, 2018

After the powder metallurgy products are vulcanized, the most prominent role is that they have good dry friction properties. Under the working conditions without oil lubrication, it is a kind of satisfactory self-lubricating material and has good seizure resistance. Reduce the snaking phenomenon.

In addition, the friction characteristics of this material are different from those of general anti-friction materials. Generally, as the specific pressure increases, the friction coefficient begins to change little. When the specific pressure exceeds a certain value, the friction coefficient increases sharply, and after the vulcanization treatment, In powder metallurgy products, the friction coefficient decreases with the increase of its specific pressure over a large specific pressure range. This is a valuable feature of anti-friction materials.
