目的 – 本文的目的是研究制造致密金属零件的选择性抑制烧结 (SIS) 工艺的基本原理。设计/方法/途径 – 开发了一种基于微观机械抑制的 SIS-金属工艺。在此过程中，盐溶液被打印在每个粉末层的选定区域；当水蒸发时盐会重结晶；盐晶体在烧结前分解并迅速生长；生成的盐颗粒在金属粉末颗粒之间扩散，并防止这些颗粒熔合在一起，从而抑制受影响区域的烧结过程。研究结果 – SIS-Metal 工艺具有许多优点。为该技术的未来发展建立了抑制烧结的机制。通过使用 STM 进行化学和视觉分析，已经确定了抑制现象的机制。研究限制/含义 – 研究中仅使用了青铜粉。因此，抑制...
Purpose – The purpose of this paper is to investigate the fundamentals of the selective inhibition sintering (SIS) process for fabricating dense metallic parts.Design/methodology/approach – A SIS‐Metal process based on the microscopic mechanical inhibition is developed. In the process, salt solution is printed in the selected area of each powder layer; the salt re‐crystallizes when water evaporates; salt crystals decompose and grow rapidly prior to sintering; the generated salt particles spread between metal powder particles and prevent the fusing of these particles together, hence inhibiting the sintering process in the affected regions.Findings – The SIS‐Metal process has numerous advantages. An inhibition of sintering mechanism is established for the future development of the technology. Through chemical and visual analysis using STM the mechanism for the inhibition phenomenon has been identified.Research limitations/implications – Only bronze powder has been used in the research. Accordingly, the inhi...
