Abstract

Stiffness is always one of two factors that determine frictional resistance. The other factor, the coefficient of friction, depends on the surface characteristics. Teflon coating reduces the sliding friction to one-half, and a hydrophilic plastic coat to about one-sixth compared with steel.

摘要

硬度始终是决定摩擦阻力的两个因素之一。另一个因素，即摩擦系数，取决于表面特性。与钢相比，聚四氟乙烯涂层可将滑动摩擦降低至二分之一，而亲水性塑料涂层可将其降低至约六分之一。
