Title: The Innovations of Stephen G. Sitko
Introduction
Stephen G. Sitko is an accomplished inventor based in Telford, PA (US). He has made significant contributions to the field of materials science, particularly in the development of advanced coatings. With a total of 2 patents to his name, Sitko's work focuses on enhancing the performance and durability of coatings used in various applications.
Latest Patents
Sitko's latest patents include a strain tolerant ceramic coating and a method and apparatus for applying coatings using a nozzle assembly. The strain tolerant ceramic coating is designed for use as an abrasive coating on substrates. It is prepared from yttria and zirconia powder with an average particle size of less than 40 microns. This innovative coating is applied using a plasma spray process, resulting in a coating that contains essentially no macrocracks. However, a post-stressed coating exhibits a random distribution of microcracks and macrocracks, enhancing its performance under stress.
The second patent, a method and apparatus for applying coatings using a nozzle assembly, modifies known thermal spray apparatus to achieve coatings of increased hardness. This apparatus develops a plasma stream that is introduced to a nozzle for application to a substrate's surface. The design includes a plasma cooling zone and a plasma accelerating zone, which work together to enhance the quality of the thermal spray coatings. By increasing the ratio of the length of the plasma/particle confining zone relative to its diameter, Sitko's method achieves particularly desirable results with various coating materials.
