TL;DR: In this paper, the war resistance of Al2O3/TiB2 ceramic composites with different TiB2 content in sliding wear tests against cemented carbide (WC+Co) at temperatures ranging from 25 to 900°C and in cutting processes, have been studied to further optimize the war resilience of Al 2O3.

TL;DR: In this article, the authors developed composite coatings (fluoropolymer/ceramic) by plasma spaying, which are characterized by a well-melted ceramic matrix in which rounded polymer particles are randomly distributed.
Abstract: Even if polymer coatings are widely used for industrial applications, their performances are often limited by a poor scratch resistance or a high water and gas permeability. To overcome such limitations, the composite coating of ceramics with polymer can be a solution to be adopted. Thermal spraying may help to achieve this objective, thanks to its ability permitting to deposit many kinds of materials with an important range of coating thicknesses. The aim of this paper is to develop composite coatings (fluoropolymer/ceramic) by plasma spaying. Due to different thermal characteristics of the initial materials (PTFE or PFA polymers and Al 2 O 3 –TiO 2 ceramic), three types of powders injections are elaborated. To compare these three conditions, microstructure, surface wettability and wear resistance deposits behaviour were characterized. Al 2 O 3 –TiO 2 /fluoropolymer (PTFE or PFA) composite coatings are characterized by a well-melted ceramic matrix in which rounded polymer particles are randomly distributed. The as-sprayed polymer particles kept at the coatings surface can however be spread thanks to a thermal treatment at 350 °C during 15 min. Unlike the PFA, a large PTFE loss was noticed during the spraying process. Thus, the highest polymer/ceramic ratio is observed in the coatings made with the separated injection of the Al 2 O 3 –TiO 2 and PFA powders. The lowest friction coefficient is also measured for this coating.

Abstract: A fuel cell comprises an anode, a cathode, a solid electrolyte disposed between the anode and the cathode, and interconnect means for providing an electrical connection located adjacent to either the cathode or the anode but not adjacent to the solid electrolyte. The interconnect means includes an interconnect layer having a composition of (i) a mixture of an electrical conductor and a ceramic matrix material that is sinterable in an oxidizing atmosphere at a temperature of less than about 1500° C., (ii) a mixture of a lanthanum chromite-based ceramic and a yttrium chromite-based ceramic, or (iii) a yttrium chromite-based ceramic of the form Yw-x-y Cax Zry Crv-z Znz O3 , where w is from about 0.9 to about 1.1, x is from about 0.1 to about 0.3, y is from about 0.001 to about 0.1, z is from about 0.1 to about 0.3, and v is from about 1 to about 1.2.
