摘要： Disclosed is a method and apparatus for forming a circumferential skin surrounding a central cellular structure of an extruded honeycomb article. The method and apparatus may be used to produce defect-free skins and/or skins having large thickness and a high degree of particle alignment thereby preferably exhibiting CTE comparable to the extruded webs. These benefits are achieved by providing a die and method wherein a flow, Q, exiting any two active ones of a plurality of peripheral slots forming the skin is substantially equal. Also disclosed is a thick-skinned ceramic article having a thick extruded skin (ts′>5 tw′) with an I-value comparable to the webs.

摘要： Methods are provided for testing a honeycomb body comprised of a core portion comprising honeycomb cell walls and a circumferential skin portion overlying at least some outer honeycomb cell walls. The circumferential skin portion includes a cement mixture layer. The method comprises the step of directing a fluid stream from a pressurized fluid source at the honeycomb body. The fluid stream is capable of separating at least part of the skin portion from the outer honeycomb cell walls when the adherence between at least part of the skin portion and the outer honeycomb cell walls is below a minimum threshold. In one example, the method further comprises the step of inspecting at least part of the interface between the honeycomb body and the skin portion during or after directing the fluid stream at the honeycomb body. In further examples, an apparatus is provided for testing the honeycomb body.
