of the BN and MnS inclusions exist individually in the steel and only a small amount of them are in a composite state forming either isolated particles or clusters of particles. In the case of multi-phased steel, the theoretical calculation predicts that the volume of large BN particles should be 0.7 times of the volume of large MnS particles. The machinability of this type of BN and MnS alloy steel......

Institute of Technology, Harbin 150001, China)Abstract:The electric double layer with the transmission of particles was presented based on the principle of electrochemistry. In accordance with this theory, the cavitation catalysis removal mechanism of ultrasonic-pulse electrochemical compound machining (UPECM) based on particles was proposed. The removal mechanism was a particular focus......

. The Co particles are mainly in the range of 8–27 nm and form dense/continuous soft magnetic coatings on the surface of SmCo5 powders. Exchange coupling happened between the coated Co soft magnetic particles and the SmCo5 hard phase. As a result, SmCo5/Co nanocomposite powders with remanence of73.58 emu/g and energy product of 13.74 MGOe were obtained in the optimum condition, as compared with those......
Effect of solid particles on gear tooth failureAbdelouahab BOUCHIREB1, Mohamed Rafik SARI1, 2(1.

In fact, the effect of the presence of solid particles in gear mechanisms during surface tooth contact was observed. It is shown that the solid contaminants lead to significant wear in the first......
