Title: Harold A Sreshta: Innovator in Thermal Treatment and Powder Composite Technologies
Introduction
Harold A Sreshta is a notable inventor based in Houston, TX (US), recognized for his contributions to the fields of thermal treatment and powder composite technologies. With a total of 7 patents to his name, Sreshta has made significant advancements that enhance the performance and durability of various materials.
Latest Patents
One of Sreshta's latest patents is focused on methods of treating preform elements. This innovative method involves thermally treating a preform element, which features a facing table of polycrystalline diamond bonded to a substrate of cemented tungsten carbide. The process includes heating the element to a soaking temperature of 550-625° C., preferably around 600° C., maintaining that temperature for at least one hour, and then cooling the element to ambient temperature. This treatment results in a preform element with a substrate that has a cobalt binder, including a substrate interface zone with at least 30 percent by volume of the cobalt binder and a hexagonal close-packed crystal structure. This innovation significantly reduces the risk of cracking or delamination during use.
Another notable patent by Sreshta is related to the fabrication process for powder composite rods. This invention describes a method of forming a powder rod core by injecting a powder mix material into a mold, moving the mold to a curing station, and subsequently injecting material into a second mold.
