Latest Patents
Suri's latest patents focus on enhancing the performance and durability of razor blades. One of her key inventions involves martensitic stainless steel cutting edges that exhibit superior corrosion resistance. These blades contain only between 0.30% to 0.45% carbon, yet they achieve hardness levels equal to or better than those made from higher carbon content steels. The production process involves treating the blades prior to hardening to ensure a fine carbide microstructure, which is crucial for maintaining their cutting efficiency.
Another significant patent details a process for producing long-lasting corrosion-resistant carbon steel razor blades. This innovative method includes coating the cutting edges with chromium and immersing the blades in an electroless coating bath. This process results in a protective layer of nickel-phosphorous or other similar materials, which prevents the need for frequent resharpening. Additionally, the blades can be overcoated with a specialized silicone oil composition to enhance their longevity.
