Electrical steel is a steel produced in thin strips which can be stacked together to form a magnetic core in electromagnets. Such electromagnets are used in electrical transformers or electric motors, but the electromagnets used in these applications can suffer from electrical losses called “eddy current” and “hysteresis” losses. One effect of these losses is the audable hum produced by transformers. Whereas hysteresis losses arise from turning on and off the electromagnet, eddy losses arise due to the materials used in the electromagnet. Carbon based materials, such as diamond like carbon, can be used to minimise the energy losses due to the eddy currents. For example, even a 1 % improvement in these losses will give a reduction of three to four tonnes of carbon dioxide per tonne of electrical steel over the 25 year transformer lifetime.This project aims to identify a suitable technology for producing conformal diamond-like carbon coatings over large areas on steel substrates. Integration of the diamond-like carbon into electromagnet technology will produce more efficient transformers and electrical motors for green technologies, such as electric vehicles.

电工钢是一种用细条制成的钢，这些细条可以堆叠在一起在电磁铁中形成磁芯。这种电磁铁用于变压器或电动机，但在这些应用中使用的电磁铁会遭受称为“涡流”和“滞后”损耗的电损耗。这些损耗的一个影响是变压器产生的可听的嗡嗡声。而迟滞损失产生于电磁体的打开和关闭，涡流损失产生于电磁体中使用的材料。碳基材料，如类金刚石碳，可以用来最大限度地减少涡流造成的能量损失。例如，在25年的变压器使用寿命中，即使这些损耗改善1%，每吨电工钢也会减少3到4吨二氧化碳。该项目旨在确定一种合适的技术，用于在钢基体上大面积生产保形类金刚石涂层。将类金刚石碳整合到电磁体技术中，将为电动汽车等绿色技术生产更高效的变压器和电动机。
