GKN Powder Metallurgy: A strategic vision for the future of permanent magnets for EVs

The transition to clean energy, acceleration in EV uptake, and demand from other renewable technologies means the market for permanent magnets is growing rapidly. GKN Powder Metallurgy recently announced it will begin manufacturing permanent magnets specifically for the EV markets in Europe and North America and is investing significantly to establish the capacity to produce up to 4,000 tonnes by 2025. Here, GKN PM shares its vision for the electric motor market and its plans to create local-to-local supply chains for permanent magnets, with insight from Thorsten Wieres, Global Program Director Magnets, and Eckart Schneider, Director of Business Development.

Building trust in the Powder Metallurgy industry: The role of standardisation and an update on recent work by ISO/TC 119

Adhering to industry standards is crucial for fostering customer confidence and maintaining the integrity of the Powder Metallurgy field. Standards establish a framework for the language used by the industry, characterisation techniques, and material specifications. They play a vital role in both technological development and business transactions, where a clear understanding of terms, material properties, and measurement methods is necessary. In this article, Mats Larsson, chairman of the technical committee ISO/TC 119 – Powder Metallurgy, explains the importance of standardisation in PM and offers insights into the organisation’s most recent work.

High-volume powder production for Additive Manufacturing: SMS group’s continuous metal powder production process

SMS group GmbH’s newly developed continuous powder production process enables up to 4,000 tons of high-quality atomised metal powder to be produced every year for use in Additive Manufacturing and other technologies. This comes just in time to meet the challenges of a growing industrial AM market, which has seen demand for metal powder expand significantly in recent years. SMS group’s Yannik Wilkens explores the continuous powder production concept and the step change it represents in the high-volume production of atomised powders for AM.

Development of enhanced-performance PM brake pads for high-speed trains by Beijing Tianyishangjia New Material Corp., Ltd.

The new generation of high-speed trains presents a challenge for braking systems manufacturers. The increased speed at which these trains must be able to brake safely has significant implications for the required friction and wear properties of brake pad materials. Leveraging the precise property control made possible by Powder Metallurgy, Beijing Tianyishangjia New Material Corp., Ltd. (TYSJ) has designed and fabricated a series of brake pads suitable for these applications and is a key supplier of these components for ten of China’s high-speed trains. In this article, Dr Hongzhou (Andy) Zhang reports on the R&D behind TYSJ’s high-speed brake pads.

The START project: Creating a sustainable supply chain for green energy harvesting products by Powder Metallurgy

Sustainable Energy Harvesting Systems Based on Innovative Mine Waste Recycling (START) is an Innovation Action project co-funded by the EU and its Horizon Europe programme.

Using an advanced powder production and consolidation process, the project’s aim is to create a sustainable supply chain for green energy harvesting products by transforming sulphide materials from mining waste into sustainable high-added-value Powder Metallurgy components for tellurium-free thermoelectric (TE) devices.

Here, the consortium members offer a comprehensive summary of START’s background, the innovative workflow developed, and its potential impact.

World PM2022: Reviewing three innovative methods for metal powder production

A technical session at the 2022 World PM Congress, organised by the European Powder Metallurgy Association (EPMA) and held in Lyon, France, October 9-13, 2022, focused on a number of innovative methods for powder production.

An overview was given of a new approach to spherical powders in a range of sizes using conical laser beams; the production and processing of tungsten-based nanopowders in thermal plasma systems; and the fabrication of monodispersed spherical composite granules by electrostatic integrated granulation of nanopowder suspension.

Dr David Whittaker reviews the research presented during the session.
