There is an ongoing requirement to develop new brake disc solutions for rail vehicles which offer improved frictional performance, longer service life and lower overall mass without hugely increasing the overall cost. This feasibility study will examine the potential of using the laser cladding process to apply novel advanced ceramic particle reinforced metal matrix composite material as an improved frictional wear surface to discs. It will also examine the feasibility of remanufacturing worn discs at the end of their service lifetime and refurbishing them to a standard to allow their re-insertion back into service, coupled with the addition of the improved performance friction cladding. The process will be demonstrated on full size worn discs and a full cost benefit analysis conducted to assess the commercial viability of this approach, which is expected to contribute significant reductions in operational costs and carbon footprint.

人们一直需要开发用于轨道车辆的新型制动盘解决方案，这些解决方案提供改进的摩擦性能、更长的使用寿命和更低的总质量，而不会大幅增加总成本。本可行性研究将探讨使用激光熔覆工艺应用新型先进陶瓷颗粒增强金属基复合材料作为改进的摩擦磨损表面的光盘的潜力。它还将研究在使用寿命结束时再制造磨损的制动盘并将其翻新到标准的可行性，以允许其重新插入服务，并增加改进性能的摩擦覆层。该工艺将在全尺寸磨损盘上进行演示，并进行全面的成本效益分析，以评估这种方法的商业可行性，预计将有助于大幅降低运营成本和碳足迹。
