Abstract | AlMgB14 based composites are promising candidates for use as cutting tool etc. In this respect, tribological behavior is one of the most important performances among all the criteria. In this work, a novel AlMgB14-30 wt% Si composite (referred to as BMAS30) was prepared by Spark Plasma Sintering. and its tribological property was investigated under different counterface materials (316L and Si3N4) and loads in ambient environment. Besides, the fracture toughness and the hardness were measured. We found that BMAS30 has a good fracture toughness of 5.90 MPa•m1/2 and a super-high hardness of 27 GPa. In terms of the tribological properties, BMAS30 shows good tribological properties when sliding against 316L, i.e., a lower friction coefficient of 0.19-0.28 and wear rate of 7.00-8.00 × 10-6 mm3/N m, while it presents a relatively high friction coefficient of 0.35-0.46 and wear rate of 3.80-9.00 × 10-5 mm3/N m when sliding against Si3N4. In the former case, large numbers of Si grains pull-out pits formed on the worn surface that can store wear debris, which is conducive to lower the friction and wear; the latter produces severe fatigue fracture under high Hertz contact stress and thereby aggravates the friction and wear. |
