Title: Walter Gaertner: Innovator in Bi-Material Sliding Bearings
Introduction
Walter Gaertner is a notable inventor based in Gmunden, Austria. He has made significant contributions to the field of sliding bearings, holding a total of 3 patents. His innovative methods and designs have advanced the technology used in this essential component of machinery.
Latest Patents
One of Gaertner's latest patents is a method for producing a bi-material sliding bearing. This invention involves depositing a metal sliding layer of at least two different particle types under reduced pressure from the gas phase onto a flat metal substrate. The first particle type forms a matrix with first grains, while the second particle type forms grains embedded in the matrix. The resulting metal sliding layer has a thickness of more than 250 µm and a Vickers hardness below 100 HV(0.025). Additionally, the metal sliding layer is produced in a single pass with a maximum grain size of at most 1 µm for at least 90% of the first grains.
Another significant patent is for a multi-layered plain bearing. This invention comprises a sliding layer made from a tin-based alloy, which contains specific percentages of antimony, copper, and other elements. The sliding layer is deposited using a PVD method when the particle size of the nanoparticles exceeds 50 nm. This innovative approach enhances the performance and durability of sliding bearings.
