Latest Patents
Among his notable inventions are two latest patents that showcase his ingenuity. The first is a patent focusing on a **steel composition** that enhances chain parts and steel articles with hard, wear-resistant carbide coatings. This innovative method involves tumbling the steel components in a heated retort with a specialized particulate mix containing a source of vanadium and/or niobium. The unique steel substrate comprises at least 0.2% carbon, ideally ranging from 0.7% to 1.2%, and features 4-12% chromium content. Notably, the chemical deposition process allows for the infusion of chromium from the steel substrate into the carbide coating, ensuring a homogeneous distribution and improved adhesion strength, which is crucial for durability.
The second patent revolves around a **blade tensioner**, which is engineered with a blade shoe that has a chain sliding face. This tensioner incorporates several plate-spring-like blade springs positioned on the reverse side of the sliding face to apply a consistent spring force. It also features spacer members that maintain a fixed distance between adjoining blade springs, optimizing the damping factor of the system and resulting in stabilized performance.
