3D Surface Roughness Parameters of Nanostructured Coatings with Application in the Aerospace Industry

Abstract

This paper presents a study of 3D surface texture measurements and analysis of several surface texture parameters. A stylus measuring instrument was used to measure 3D surface topographies. In experimental part of this study, two coated gas turbine blades used in aerospace industry were chosen to examine surface of the coatings in nano-scale. Surface texture parameters of Ti-Al coating and Ti-Al-N coating were measured and compared to each other. The aim of the research is to analyze the surface of these coatings in an areal (3D) manner. The results indicate slight differences between these two surface textures despite the fact that both are Titanium-based coatings, and the surface of base material for both samples was prepared in the same way before deposition. Further study with repeated measurements of surface texture for deposed coatings has to be made after erosion tests.

Engineered Nanomaterials for Aviation Industry in COVID-19 Context: A Time-Sensitive Review

“…Promising contact points above 150 • were uncovered that in the wake of playing out a de-icing test on different occasions, the examples gave fantastic de-icing abilities. On the other hand, thermal barrier coatings also have gained widespread attention due to their ability to accommodate better thermal cycle life, decreased tendency for sintering in grained columnar structures, and lessen thermal conductivity [65][66][67]. Also, thermal barrier coatings can function as temperature sensors or high-temperature electronics and remote transmitters [67].…”
