The Role Of Graphite In Friction Materials

Short Description:

Adjusting friction coefficient, as wear-resistant lubricating material, working temperature 200-2000°, Flake graphite crystals are flake like; This is metamorphic under high intensity of pressure, there are large scale and fine scale. This kind of graphite ore is characterized by low grade, generally between 2 ~ 3%, or 10 ~ 25%. It is one of the best floatability ores in nature. High grade graphite concentrate can be obtained by multiple grinding and separation. The floatability, lubricity and plasticity of this kind of graphite are superior to other types of graphite; Therefore it has the greatest industrial value.

Product Usage

D465 brake pads with different graphite content were pressed by dry powder metallurgy, and the effects of artificial graphite on the properties of friction materials were studied by LINK inertial bench test. The results show that artificial graphite has little effect on the physicochemical and mechanical properties of friction materials. With the increase of artificial graphite content, the friction coefficient of friction materials decreases gradually, and the wear amount decreases first and then increases. The effect of artificial graphite on the noise occurrence of friction materials also presents the same trend. According to the comparison of physical and chemical properties, mechanical properties, friction coefficient and wear data, the friction material has the best friction and wear performance and noise performance when the content of artificial graphite is about 8%.

Application

In the production process of raw materials after high temperature graphitization and purification treatment, high purity, high degree of graphitization of artificial graphite is easier to form a transfer film on the friction material and the dual surface, its wear reduction performance is excellent;
Less impurity content: does not contain silicon carbide and other hard particles that can produce noise and scratch the surface of the pair;
