A brake assembly and a method for manufacturing a brake assembly are provided. The brake assembly includes a brake pad affixed to a substrate. The brake pad extends from the substrate to a brake pad friction surface, and includes abradable cellular metal foam with the hardened ceramic particles.
摘要:
A method of and system for repairing the sheaves (24) in an elevator system has these steps. The ropes (22) associated with the sheave are removed, the sheave is cleaned, and a coating (24) is deposited on the cleaned surface. The coating is adapted to reduce the wear coefficient of the surface of the coated sheave by about 80% to 90% with respect to the sheave without a coating. The thickness of the coated sheave is adjusted to produce a specified sheave diameter.
摘要:
A coated sheave (24) for use in an elevator system in having at least one rope (22) and sheave combination, where the sheave has a predetermined shape and size for engagement with at least one rope in the elevator system. A coating (27) on the sheave has a wear coefficient of at least 80% less than the wear coefficient of the sheave without the coating.
摘要:
An erosion resistant and hydrophobic article includes a core that has a first hardness and a surface on the core. The surface includes a plurality of geometric features that have a second, greater hardness. The geometric features define a surface porosity by area percent and a corresponding surface solidity by area percent. The surface includes a ratio of the surface solidity divided by the surface porosity that is 1.8 or greater. The geometric features and the ratio establish the surface to be hydrophobic, and the second, greater hardness and the ratio establish an erosion rate of the surface that is equal to or less than an erosion rate of the core under identical erosion conditions.
