Active Screen Plasma Nitriding – An Efficient, New Plasma Nitriding Technology

Active screen plasma nitriding technology (ASPN) is a new industrial solution that enjoys all the advantages of traditional plasma nitriding but does not have its inconveniences. Different-size parts can be treated in the same batch. It also offers the possibility of oxynitriding and nitriding of stainless steels.

	Additive Manufacturing Enables Innovative Shock-Wave Control in Supersonic Turbine Blades Scientists at von Karman Institute in Belgium contracted LayerWise to produce a scaled turbine inlet guide vane model for a turbine research project. LayerWise built the metal-vane specimen as a single part, complete with internal cooling cavity and fine instrumentation channels. by Rob Snoeijs

Impact of Measurement Errors on the Results of Nitriding and Nitrocarburizing Treatments

We have a pretty good idea of what will happen to steel parts if exposed to a defined atmosphere at a given temperature. In order to determine the process parameters, we can use the well-known Lehrer Diagram for a nitriding process, or we might use one of the various Fe-N-C phase diagrams for a nitrocarburizing process.

	New Configuration May Make it Harder to Say No to Thermal Regeneration Thermal regeneration is a proven technology that is generally accepted as the most efficient means of heating an industrial furnace. But regenerative systems, though commonplace, are far from the norm in the industry. by Sean Barraclough Bryan J. Kraus
