摘要： Disclosed is a ceramic honeycomb structure comprising a honeycomb body and a multilayered outer layer formed of a thick core layer applied and rapidly dried and a thin clad layer dried more gently to form a crack free dual skin layer. The core layer may have properties that are closer to those of the ceramic honeycomb body in service than the clad layer that may provide a tough outer shell to withstand handling and assembly.

摘要： A control system for an axial skinning apparatus (100), including: •a force to cause a ceramic honeycomb part (110) to pass through the skinning apparatus (100); •a force that urges flowable cement on to the ceramic honeycomb part (110); •a sensor to detect the force on the cement; •a sensor to detect the force on the ceramic part; and•a controller (300) which receives: •a signal from the sensor on the flowable cement, •a signal from the sensor on the ceramic part (110), or both, and the controller (300) controls the pressure set point (310) of the cement source based on one or both of the received signals, and the controller (300) adjusts control parameters using feedback control and pseudo feed forward control. A method of using the axial skinning apparatus (100) is also disclosed.
