Molybdenum transmission Discs


Molybdenum friction materials are commonly used in low speed & high pressure applications. The steel core plate is coated with pure molybdenum at a thickness ranging between 0.045 – 0.070mm per face. The process used is thermal spraying also known as flame spraying. Once this process is finished the final thicknesses & groove patterns are then machined to the surface to guarantee reliable friction behaviour. The following are properties that are associated with this type of material:


> Good oil compatibility
> Good wear resistance
> Stable friction Coefficient
