With a total of 3 patents to his name, Agrawal's work has advanced the methods used in fabricating complex metal structures.
Latest Patents
Agrawal's latest patents include innovative methods for fabricating superplastically formed and diffusion bonded structures. One of his patents describes a method where metal blanks of a titanium alloy are joined at selected areas by diffusion bonding. This process allows for the formation of desired sandwich or integrally stiffened structures. The method involves treating the metal blanks with a 'stopoff' material to prevent bonding in specific areas during diffusion bonding, enabling shaping during superplastic forming. An improved stopoff compound, made from yttria of relatively coarse particle size, is utilized to achieve this.
Another patent focuses on enhancing the superplastic forming process by using release coatings with different coefficients of friction. This improvement allows for more controlled expansion of preforms against forming members, optimizing the manufacturing process. The preferred coatings used in this method are boron nitride and yttria, which help achieve the desired results.
