Abstract: At present, titanium alloy spring has been used in equipment in aerospace, marine ships, automobiles, petrochemical engineering and other fields. It is a key part to provide preloading and energy storage, shock absorption and other functions for important equipment and products. Spring load force and reliability have a vital impact on the service performance and life of the equipment. In order to enhance the performance and service life of titanium alloy spring and improve the quality of equipment and products, the process of titanium alloy spring is optimized. Improving the performance and reliability of titanium alloy spring is one of the directions worthy of attention and research.
