Latest Patents
Otfinoski's latest patents include innovative technologies aimed at improving the erosion resistance of abradable seals. One of his patents, titled "Abradable seal having particulate erosion resistance," describes a method where porous plasma arc sprayed powder metal abradable materials are enhanced with a thin ceramic surface layer containing fine aluminum particulate. This unique approach ensures that the particulate and ceramic matrix material fill the surface pores without compromising the desirable abradability characteristics.
Another significant patent is for "Porous metal abradable seal material." This invention highlights the utility of porous metal structures as abradable seals in axial flow compressors. The carefully defined oxide content and density of these seals provide an exceptional combination of abradability and particulate erosion resistance. The preferred seal is created by plasma arc spraying a mixture of 80Ni-20Cr and polymethylmethacrylate powders, followed by heating the resultant deposit to remove the polymer, resulting in a highly effective seal.
