TLDR: Key Points
- Vehicles, including electric cars, emit carbon-based particulate matter from the fine dust created when braking, and these emissions can contribute up to 55% of all harmful non-exhaust traffic-related emissions in high-density urban environments.
- The European Parliament has delayed stricter Euro 7 emissions standards until mid-2030, but the proposed regulations are expected to focus more on non-exhaust emissions.
- Cold spraying coatings technology, a material deposition technique, is being developed to cost-effectively meet new particulate emissions regulations and provide better corrosion resistance for brake discs.
- The Linspray Connect system, developed by Linde and Impact Innovations, ensures the delivery of a reliable, stable, and high-quality gas flow for cold spray coating processes.
Air quality in mature economies is improving due to electric vehicles, yet brake wear can still produce harmful non-exhaust traffic-related emissions consisting of carbon-based particulate matter (PM). Brake emissions, now the dominant source of coarse and fine particulate matter from road transport in the UK, cause significant environmental and health concerns. Stricter Euro 7 emissions standards will focus on non-exhaust emissions, including brake wear. Cold spraying coatings technology provides emission reduction solutions by coating brake discs with a combination of metal alloys and ceramic powders for better corrosion resistance. Linde’s Linspray Connect system helps deliver reliable, stable, and high-quality cold spray coatings by monitoring process parameters and ensuring a consistent gas flow.
