Net shape parts of typically intricate and complex shape obtained by powder metallurgy (PM) are employed in several key mass industry sectors, especially automotive, aerospace and medical. Their use is growing rapidly in preference to conventional casting because the process produces parts in the precise final shape required with little or no machining requirement combined with fine grained (nano-micro scale), homogeneous microstructures of enhanced strength. However there is a lack of production quality control as little in-line inspection is performed. End-of-line inspection, not often performed, leads to scrapping of 6-8% of components yet fails to detect micro sized defects, which can grow in service to produce major in service failures and recalls. THE PROJECT VISION is an in-line quality control system (QUALINET) using 3D microfocus x ray imaging (µXCT) with AUTOMATION INNOVATIONS (A) Detection and characterization of volume and surface micro-scale defects at the pre and post sintering stages. (B) Decision making: (i) component acceptance or (ii) send for recycling or (iii) send with a prescription for defect healing treatment. QUALINET will eliminate waste, increasing line production, reducing energy consumption and carbon emissions, all by 8%. The benefit will be optimal for state of the art PM component lines including additive manufacturing by laser deposition, nano-powders and injection moulding. Estimated ROI comprising the profits of the partners, licensees and the savings in reduced waste from the PM systems on which the QUALINET sold system would be installed are 111:1 in the EEA and 35:1 over the first 5 years of commercialisation. Global acceptance of the net technolgy could save £340mpa.

粉末冶金（PM）获得的通常复杂且复杂形状的净形部分用于多个关键的群众行业，尤其​​是汽车，航空航天和医疗。它们的使用迅速增长，优先于常规铸造，因为该过程以几乎没有或没有加工要求的精确最终形状产生零件，并结合细粒度（纳米 - 麦克罗尺度），均质的微观结构，具有增强强度。但是，由于很少进行在线检查，因此没有生产质量控制。未经常执行的线路检查会导致6-8％的组件取消，但无法检测到微型尺寸缺陷，这些缺陷可能会在服务中成长以产生服务失败和召回。项目视觉是使用3D微型焦点X射线成像（µXCT）具有自动化创新的在线质量控制系统（Qualinet）（a）在烧结前后阶段检测和表征体积和表面微尺度缺陷。 （b）决策：（i）组件接受度或（ii）发送回收利用或（iii）以处方进行缺陷愈合治疗。 Qualinet将消除浪费，增加生产，减少能源消耗和碳排放，均下降8％。这些好处将是最先进的PM组件线，包括激光沉积，纳米蛋白和注入成型的添加剂制造。估计的投资回报率补充了合作伙伴，许可证的利润以及从PM系统中安装的PM系统减少废物的利润，在EEA中安装了111：1，在商业化的前5年中为35：1。全球对净技术的接受可以节省340mpa。
