Abstract

The production of metals by additive manufacturing is developing rapidly. After production, support structures emerge as waste materials. In this study, Ti6Al4V support structures recycled from the selective laser melting process were consolidated by vacuum hot pressing. Spherical and irregularly shaped Ti6Al4V alloy particles were also used for the comparison as raw materials. All raw materials have been subjected to the same sintering process by hot pressing. The microstructures of the samples were carried out, and their dry sliding wear performance was studied. The samples produced from support structures showed the highest wear performance compared to the powder forms of raw materials. This study showed that the support structures from additive manufacturing could be recycled and transformed into full dense structures by pressure-assisted sintering techniques, and enhanced wear performance can be obtained.

支持增材制造中的回收:Ti6Al4V合金增强磨损性能的案例研究

金属增材制造技术正在迅速发展。生产后，支撑结构作为废料出现。在本研究中，采用真空热压的方法对选择性激光熔化工艺回收的Ti6Al4V支撑结构进行固结。还采用球形和不规则形状的Ti6Al4V合金颗粒作为原料进行了比较。所有原料都经过相同的热压烧结工艺。对试样进行了显微组织分析，并对其干滑动磨损性能进行了研究。与粉末形式的原材料相比，由支撑结构生产的样品显示出最高的磨损性能。研究表明，增材制造的支撑结构可以通过压力辅助烧结技术回收并转化为全致密结构，并且可以获得增强的耐磨性能。

期刊介绍： The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there."
