3D-printed nozzle ring

The premature erosion of nozzle rings is a commonly reported problem which creates unplanned down times and emergency service attendance. When this happens spare part replacements are usually unavailable and can come with high costs.

Tru-Marine has developed proprietary processes in 3D printing and offers nozzle rings repairs by way of layerwise building, this enables reconstructing worn out areas directly onto the original component.

The company argue that by using exotic metal that surpasses current casting standards, it can promise improved heat and corrosion resistance as a value gain. Exotic alloys have a high ultimate tensile strength so that when they are processed using additive manufacturing near perfect densities of greater than 99.5% are achieved.

Alongside this, the capability for geometric complexities with 3D printing also allows for the perfect match of every profile in accordance to the technical specifications of each nozzle ring model.

Positive results in strength and microstructure laboratory examinations show that the 3D nozzle rings have been tested to be suitable for turbocharger applications. This comes with the support of government agencies and local research institutions, lending greater confidence and acceptance of the repair innovation.

Tru-Marine said its in-house research and development focused on expanding its product and service lines using indigenous technologies. The company claims to have a strong reputation for generating disruptive technology that phases out market practices which have become sub-optimal in productivity and relevance.
