自从第一个铁谱片(Ferrogram)制备出来之后不久,人们就已认识到,磨损颗粒可以按照其产生的方式和形态而分为有限的几种典型种类。大部分正常运转的机器,当其金属摩擦面处在边界润滑状态下互相滑动时,都会产生所谓的“摩擦磨损颗粒”(Rubbing WearParticles)。由于这时机器通常处于正常磨损状态,所以这类粒子也称为“正常磨损颗粒”(Normal Wear Particles)第二类典型磨损颗粒称之为“切削磨损颗粒”(Cutting WearParicles)。它是由于两滑动表面硬质微凸体或外来硬颗粒向对偶面切削面形成的,因其形 Shortly after the first Ferrogram was prepared, it has been recognized that wear particles can be classified into a limited number of typical species according to the manner and form in which they are produced. Most machines that operate normally produce so-called “Rubbing WearParticles” when their metallic friction surfaces slide against one another at boundary lubrication. Since the machine is normally in normal wear and tear at this time, these particles are also referred to as “Normal Wear Particles.” The second type of typical wear particles is called “Cutting Wear Particles.” It is due to the two sliding surface of the hard asperities or foreign hard particles to the dual surface cutting surface, because of its shape
