Abstract Scope |
Coating application is identified as one of the complex engineering problems in the manufacturing of devices in automotive, aerospace & medical. Inadequate coating on the substrate can impact the robustness of the coating and may cause adverse effects on device performance. The objective of the present study is to evaluate the influence of key coating processing parameters to better understand the relationship between coating thickness and the parameters which helps to determine the durability and effectiveness of coating on the device. In this study, numerical modeling of dip-coating process on the device is carried out using Ansys-Fluent. The dynamic contact angle has been imposed on the fluid-solid interface through a UDF to accurately capture the fluid behavior and film thickness formation. The influence of coating film thickness due to various parameters like extraction speed, viscosity, surface tension of coating material, surface roughness and dynamic contact angle are evaluated. |
