【Abstract】 Deposition and properties of (TiAl)N have been investigated by filter arc evaporation. The size and density of macroparticle in (TiAl)N films are considerably decreased under the basement of electron’s and ion’s movement in the straight filter. The bias voltage appears to be the main parameter controlling the final composition in the conventional arc evaporation process. But under the filter arc evaporation process, the influence of the bias voltage on the final composition of the (TiAl)N are abated. Increasing aluminum content leads to an increase in surface hardness. The oxidation resistance of the (TiAl)N is obviously superior to that of TiN film.更多还原
