Abstract

Thermogravimetry, combined with differential scanning calorimetry and single-wave ellipsometry, was used to study the thermal stability and protective properties of oxide films of Al–2.3% V alloy powder in compressed and bulk forms over a temperature range of 25–1200°C in air. Optical constants measured on massive polycrystalline samples were employed to examine the growth of the oxide layer and the change in the metal content on the surface of the initial aluminum and Al–2.3% V alloy powders compressed into tablets. The influence of the vanadium alloy additive on the structural changes of the surface oxide of aluminum powder under conditions of programmable heating was explained.

3D打印用Al-2.3% V合金基粉末的理化性能研究
采用热重法、差示扫描量热法和单波椭偏法研究了Al-2.3% V合金粉末在25 ~ 1200℃空气中压缩和块状氧化膜的热稳定性和防护性能。用光学常数测量了块状多晶样品中氧化层的生长情况以及铝和Al-2.3% V合金初始粉末压片后表面金属含量的变化。阐述了钒合金添加剂在可编程加热条件下对铝粉表面氧化物结构变化的影响。

期刊介绍: Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
