Tesla teardown: Identifying potential uses for PM in electric vehicle transmissions

Whilst the future looks electric, with ever more electrically-powered vehicles entering the market, there are still lucrative opportunities for the Powder Metallurgy industry.

Höganäs AB’s Dr Anders Flodin, a long-time advocate of PM transmission gears for conventionally powered cars, and Babak Kianian, PhD candidate at Lund University, believe that one such opportunity is for PM gears in EV transmissions. To understand more, a Tesla Model S was the subject of a teardown and its transmission components analysed to understand if PM alternatives are suitable for such an application, and what advantages they might bring.

Can European research still claim to be ‘world class’? Prof José M Torralba on the changed PM research base

In the history of the Powder Metallurgy industry, Europe has been a research leader, with major European universities and research institutes paving the way to the identification of new materials, processing techniques, and applications for the technology. But is that still the case in 2021?

In this article, Dr David Whittaker speaks to Prof José M Torralba, a leading expert in the European PM research landscape, and hears his views on the current state of global PM research, the factors limiting development in the European PM industry, and directions for future research and development.

How to make metal powders. Part 1: An introduction to atomisation, process fundamentals and powder characteristics

The rise of metal Additive Manufacturing has resulted in renewed interest in metal powder production. A market once dominated by a small number of specialist powder producers has now seen the arrival of a diverse range of competitors, all hoping to capitalise on the promised opportunities of metal powder-based part production. As many are discovering, however, making powders with the required characteristics, to the necessary standards, and profitably, is far from easy.

Here, in the first instalment of a four-part series, two masters of metal powder atomisation, Joe Strauss and John Dunkley, introduce the process.

Powder Metallurgy: The original net-shape production process

Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
