Titanium alloys are produced industrially by smelting. However, remelting is necessary to achieve the required quality. Additional process steps are necessary to adjust microstructure and composition, which is especially important for applications in the aerospace industry.Molten salt electrodeposition would make it possible to produce titanium alloys in fewer steps. By varying the deposition parameters, the microstructure and composition can be adjusted.There are opportunities in the field of surface treatment (coating) and electroforming, for example the direct production of slabs and plates. Another interesting possibility is the production of powders for powder metallurgy.As an application example of the evolving technology the manufacturing of titanium matrix composites is planned. The silicon carbide fibers are coated with the titanium alloy Ti6Al4V and then compacted to form a composite material.

钛合金在工业上是通过熔炼生产的。然而，重熔是达到所需质量所必需的。为了调整组织和成分，需要额外的工艺步骤，这对航空航天工业的应用尤为重要。熔盐电沉积将使生产钛合金的步骤变得更少。通过改变沉积参数，可以调整微观结构和成分。在表面处理(涂层)和电铸领域存在机会，例如直接生产板材和板材。另一个有趣的可能性是粉末冶金粉末的生产。作为不断发展的技术的应用实例，钛基复合材料的制造是计划中的。在碳化硅纤维表面涂覆钛合金Ti6Al4V，然后压实成复合材料。
