Organic silicate of 45 steel and gray cast iron HT150 Friction Performance

Friction contact surfaces can play a fine grinding, polishing effect, greatly reduce the surface roughness. (2) ultra-fine mineral powder and its products, enabling friction surface hardening,mbt schuhe auslaufmodelle, resulting in a strong non-uniform plastic deformation, which greatly improve the surface hardness. (3) ultra-fine mineral powder and substrate materials makes the local product had a strong work hardening, thereby greatly increasing the carrying capacity of the specimen and wear resistance. (4) ultra-fine mineral powder samples can improve the ability of anti-avulsion, and killed, thus greatly improving its resistance to adhesive wear ability. Mount Saint materials on a variety of machines (different materials and working conditions) has a wide range of effective adaptation, and surface finishing process will maximize the use of machinery and equipment extends to the process. Mount St. techniques used, no demolition, no parking, modification, repair, anti-friction conditions in the normal operation of the auto-complete. Its application can not only reduce friction wear and to improve efficiency and save energy, but also reduce pollution and can be applied to all friction and wear of machinery and equipment, is indeed \Reference】【l Zhang Dong.
