摘 要：Amorphous WB2/Ti multilayer coatings with different modulation ratios(1,5,15,and 30)and different bilayer numbers(10,20,30,50,and 70)were deposited by direct-current magnetron *** effect of modulation ratio and bilayer number on the microstructure,mechanical,and tribological properties of WB2/Ti multilayer coatings was studied *** the investigation for the influence of modulation ratio,the hardness of the multilayer coatings increases with the increment of modulation *** indentation toughness shows a different changing tendency compared to that of the hardness with different modulation *** wear rates of the multilayer coatings with different modulation ratios are at the same level with the influence of both hardness and indentation *** the investigation for the influence of bilayer number,both hardness and indentation toughness increase first and then decrease with an increasing bilayer ***2/Ti multilayer coating with a modulation ratio of 5 and bilayer number of 50 exhibits the highest hardness of 20.4 GPa and lowest wear rate of 1.76×10−16 m3/*** addition,the hardness strengthening mechanism and wear mechanism of the multilayer coatings were discussed in detail.
