Corewire Ltd manufacture flux-cored wire welding consumables. They also manufacture equipment which uses these wire consumables to repair and resurface a variety of high wear resistance steel components. This includes dies for the manufacture of automotive components and rolls used in the production of rolled metal. This project will explore how this current technology and capability can be evolved into additive manufacturing of full components. A key thread will be establishing and quantifying the specific challenges to moving from resurfacing by depositing a few layers of weld metal to full component manufacture using tens or even hundreds of layers. The project will therefore commence with the deposition of current resurfacing solutions (first six months) and progress with the manufacture of increasingly challenging steels and prototypical components. The challenges include higher performance steels, increased reinforcement, compositional grading, more complex geometry, etc. The research programme will include microstructural characterisation, experimental stress-strain measurement, modelling of stress-strain accumulation during additive manufacture and alloy development. High wear resistance steels will be the focus of the research programme and the research is likely to include some wear evaluation and fracture toughness testing. Alongside the scientific, technological and engineering programme the project will work with a range of existing customers and new industrial partners to identify specific applications of this emerging additive manufacturing capability.

Corewire Ltd 生产药芯焊丝焊接耗材。他们还制造使用这些焊丝耗材来修复和重修各种高耐磨钢部件的设备。这包括用于制造汽车零部件的模具和用于生产轧制金属的轧辊。该项目将探索如何将当前的技术和能力发展为完整组件的增材制造。一个关键线索将是确定和量化从沉积几层焊接金属的表面重整到使用数十甚至数百层的完整部件制造的具体挑战。因此，该项目将从沉积当前的表面重修解决方案（前六个月）开始，并逐步制造越来越具有挑战性的钢材和原型部件。挑战包括更高性能的钢、增加强化、成分分级、更复杂的几何形状等。研究计划将包括微观结构表征、实验应力应变测量、增材制造和合金开发过程中应力应变积累的建模。高耐磨钢将是该研究计划的重点，研究可能包括一些磨损评估和断裂韧性测试。除了科学、技术和工程计划外，该项目还将与一系列现有客户和新的工业合作伙伴合作，以确定这种新兴增材制造能力的具体应用。
