and lubricated conditions. HARDELL et al [12,13] studied the high-temperature friction and wear on different tool steels sliding against the Al–Si coated boron steel. TIAN et al [14] determined... system. Hence, for the sake of tensile properties, a thinner alloy coating system is more favorable. In addition, the system is less susceptible to cracking [9]. The high stress concentration when......

">In this article, a novel Al-6Zr-2P master alloy with ZrP particles was successfully synthesized, and the refining performance of this novel master alloy for the primary Si in Cu-50Si alloys was also investigated..., it is observed that the refining effect can be remarkably improved by changing the addition sequence of the raw materials. After the melting of commercial Cu, the 2.0 wt% Al-6Zr-2P master alloy and crystalline......
