    摘要： A shaft assembly includes a metallic portion and a ceramic portion. In a disclosed example, a ceramic shaft has a generally conical end that is at least partially received within a generally conical recess in one end of a metallic shaft. The recess has a first portion that has an inner surface that is received directly against a corresponding outer surface on a section of the ceramic shaft conical portion. A second portion of the recess is radially spaced from the ceramic shaft and provides a controlled gap within which a braze alloy is maintained. In one example, the second portion has an axial length that is more than twice a radial depth of the second portion. In another example, a transition surface between the first and second portions of the recess has a linear profile.

    摘要： A heat exchanger for use as a condensing heat exchanger in a gas-fired hot air furnace has a ceramic pipe forming an initial portion of a fluid flow path through the heat exchanger. The ceramic pipe receives the combustion gases from a primary heat exchanger and reduces the temperature of the combustion gases to below a certain temperature. A polymer-based structure is connected to the ceramic pipe and forms the remaining portion of the fluid flow path through the heat exchanger. The geometry and orientation of the ceramic pipe is selected so that the certain temperature of the combustion gases exiting the ceramic pipe is less than the softening temperature of the polymer-based structure. The resultant heat exchanger combines the high temperature and corrosion resistance of ceramic materials with the low cost and high corrosion resistance of polymer materials. As a result, a low cost heat exchanger can be produced which can withstand both the high temperatures of the combustion gases as well as the corrosive properties of the condensates from the combustion gases.
