ABSTRACT

The aim of this study is to investigate the effect of the etching conditions on some technologically important properties of the Ni-P coating deposited by an electroless process on 3D printed PLA and PLA-flex. The influences of the temperature and the concentration of the etching sodium hydroxide solution on the deposition rate, composition, adhesion, wetting and roughness of Ni-P coatings were determined. The studies revealed that the high temperature and concentration of the etching solution did not improve the coating properties. In regard to the wetting and adhesion properties of the Ni-P coating, the best results were obtained at concentrations of the etching solution from 100 to 200 g L−1 NaOH and at a temperature of 20–40°C. These conditions allow good wetting of the freshly deposited nickel. Etching plays an important role not only in improving adhesion, but also has an effect on the composition and thickness of the nickel layer.

蚀刻条件对 3D 打印聚乳酸化学镀 Ni-P 的影响

摘要

本研究的目的是研究蚀刻条件对化学镀工艺在 3D 打印 PLA 和 PLA-flex 上沉积的 Ni-P 涂层的一些重要技术性能的影响。确定了蚀刻温度和氢氧化钠溶液浓度对Ni-P涂层的沉积速率、成分、附着力、润湿性和粗糙度的影响。研究表明,蚀刻溶液的高温和浓度并没有改善涂层性能。关于Ni-P涂层的润湿和粘附性能,在蚀刻溶液浓度为100至200 g L -1时获得最佳结果NaOH 和 20–40°C 的温度。这些条件允许新沉积的镍良好润湿。蚀刻不仅在提高附着力方面起着重要作用,而且对镍层的成分和厚度也有影响。
