Latest Patents

Bohlen's latest patents include a method of controlling drying stresses by restricting the shrinkage of ceramic coatings. This method involves applying a non-cured ceramic coating onto a substrate and allowing it to dry until a mechanically stable outer surface layer forms. A drying control agent is then applied to inhibit the formation of a dry outer skin, resulting in a durable, cured ceramic-coated substrate free of large cracks. Another significant patent is for a fiber coating of unbonded multi-layers for toughening ceramics. This composite features a ceramic matrix reinforced with ceramic fibers, surrounded by a multi-layer ceramic coating that is not bonded to itself. This design allows the layers to separate in the presence of cracks, promoting fiber pull-out and preventing premature breakage.
