英文摘要	In this work, Al-Mg-Ti-B coatings were synthesized at room temperature via high power impulse magnetron sputtering (HIPIMS). The as-deposited Al-Mg-Ti-B coatings exhibited a dense and X-ray amorphous microstructure. It was demonstrated that the chemical composition and mechanical properties of Al-Mg-Ti-B coatings were significantly altered by applying different negative bias voltages during the HIPIMS process. The XPS results showed that oxygen concentration in the coatings was reduced from similar to 22 at.% to similar to 8 at% and the number of oxygen-boron bonds dropped with an increasing bias voltage, which contributed significantly to the improved mechanical properties. Nano-indentation results showed that the nano-hardness and elastic modulus of the HIPIMS Al-Mg-Ti-B coatings were as high as 37 GPa and 348 GPa, respectively. (C) 2017 Elsevier B.V.
