Latest Patents

Cachinhasky's latest patents focus on coatings for valve parts to prevent erosion. One of his notable inventions is a closure member designed for use in a valve. This closure member features a coating or conformal layer that covers most, if not all, of the underlying material. The layer includes pre-propagated cracks that form due to thermal cycling prior to service use. These cracks serve as stress relief to accommodate thermal stress caused by different rates of thermal expansion between the closure member and the coating. This innovative feature extends the service life of the plug, especially in highly erosive process fluids, such as those found in hydrocracking or refining operations.

Another significant patent by Cachinhasky is a coating configured for use on parts of a control valve. This coating incorporates various material layers that form a layered structure on a substrate, such as an Inconel body. The layered structure is arranged with 'stacked' individual layers that exhibit different concentrations of materials, including tungsten carbide and nickel alloy. The concentration of tungsten carbide increases from the innermost layer to the outermost layer. This design also aims to extend the service life of the parts when used with highly erosive process fluids.
