摘要

采用不同表面硬度的灰铸铁制动盘，在城市制动条件下，研究了制动盘表面硬度对制动磨损颗粒排放的影响。三种类型的制动材料-低金属，无石棉有机和半金属，被用作对应。结果表明，制动盘表面硬度显著影响制动材料表面接触高原的形貌和元素组成，以及制动材料的摩擦学性能和制动磨损颗粒排放。通过提高圆盘表面硬度，可以获得较低的摩擦系数、比磨损率和颗粒排放。此外，与非石棉有机制动材料相比，半金属和低金属制动材料的制动盘表面硬度对摩擦学性能和颗粒排放的影响更为明显。

The effect of disc surface hardness on the tribology and emission behaviors of brake materials

Effects of disc surface hardness on brake wear particle emissions were investigated using grey iron discs with various surface hardness under urban braking conditions. Three types of brake materials-low-metallic, non-asbestos organic, and semi-metallic, were used as counterparts. Results indicate that disc surface hardness significantly influences the morphologies and elemental compositions of contact plateaus on the brake material surface, as well as tribology performances and brake wear particle emissions of brake materials. Lower friction coefficients, specific wear rates, and particle emissions were obtained by increasing the disc surface hardness. Additionally, the effects of disc surface hardness on the tribology performance and particle emissions are more pronounced for the semi-metallic and low-metallic brake materials than non-asbestos organic brake materials.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
