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.

钛合金是通过冶炼工业生产的。但是，要实现所需的质量是必要的。需要其他过程步骤来调整微观结构和组成，这对于航空航天行业的应用尤其重要。莫尔滕盐的电沉积将使以更少的步骤生产钛合金成为可能。通过改变沉积参数，可以调整微观结构和组成。在表面处理（涂层）和电动型领域中，有机会，例如直接生产板和板块。另一个有趣的可能性是生产粉末冶金的粉末。作为不断发展的技术的一个应用示例，计划了钛基质复合材料的制造。碳化硅纤维涂有钛合金Ti6Al4V，然后压实以形成复合材料。
