Influence of the high-temperature annealing on the structure and mechanical properties of vacuum–arc coatings from Mo/(Ti + 6 wt % Si)N

Abstract

Scanning electron microscopy with energy dispersive element microanalysis, X ray structural analysis, and microindentation were used to study the effect of the deposition conditions in a reactive nitrogen atmosphere on the growth morphology, phase composition, structure, and microhardness of vac uum-arc multilayer coatings produced by the evaporation of cathodes from Mo and (Ti + 6 wt % Si) both after their deposition and after high temperature annealing. It has been established that the use of the composite cathode of Ti and Si allows the formation of the structure state inclined to ordering to form a two phase compound from TiN and Ti 5 Si 3 at high temperature annealing. In this case the coating hard ness increases to a value higher than 45 GPa.

New Titanium Alloys, Promising Materials for Medical Devices

“…Molybdenum is an element that is widely used as an alloying element of titanium [14,15]. Some research in the field [16][17][18] has shown that a percentage of about 20% Mo can reduce the modulus of elasticity, as it is a β-stabilizing element, leading to proper mechanical properties, similar to human bone [5].…”
