Reliability Evaluation for Aerospace Anodizing Process of Aluminum

Abstract:

Article Preview

Detail parts of airframe should have higher precision and lightweight to satisfy the requirements of safety, payload, and controllability. Due to requirement of lightweight, aluminum alloy is widely used in airframe parts. Anodizing process is an important surface treatment process uses to prevent corrosion in aluminum parts. Salt spray is the critical test to verify the anodizing process of aluminum alloy and ensure the corrosion resistance can meet the requirement of specification. This study collects the failure time of salt spray and uses statistical method to construct the suitable probability distribution of those failure data. Furthermore, analyzes the failure time of salt spray and evaluate the reliability of anodizing process. Thereby the process control engineer can use the concept of reliability to monitor the anodizing process.
