A Study on the Relationship between Anodic Oxidation and the Thermal Load on the Aluminum Alloy Piston of a Gasoline Engine

In order to analyze the influence of anodizing process on thermal load an aluminum alloy piston, dedicated temperature tests have been carried out using Hardness Plug method and results for anodized piston compared with those obtained separately original piston. addition, numerical simulations conducted field stress distribution. Simulations experiments show that maximum is 16.36% 5.4% smaller than under condition torque power, respectively. The both pistons within 50 Mpa, which meets strength requirements material at high temperature. However, area significant significantly Combined fatigue analysis data, it can be seen safety factor greater 1.8 99.13%. Therefore, adopting not only reduces load, but also helps extend its life improve reliability.
