Résumé : |
The tribological properties of a manganese phosphate treatment are optimized with consideration of the process parameters and a thermal annealing before lubrication. The analysis was first realized through a friction test. This article deals with the application of a numerical identification procedure of coating bulk behavior to the studied cases. The mechanical properties of the chosen coatings are identified using Vickers microindentation. A plastic behavior law representing the coating and its neighboring substrate is identified using an inverse approach. The obtained bulk behavior law of the coating provides an accurate understanding of the performance of that coating. Many correlations are posited between the behavior laws, such as resistance to seizure and other characterization results, particularly SEM examination and coating weight. This knowledge leads to an objective optimization of the manganese phosphating process using finite element computation. |
