<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an alumina coating on a component having a silicon carbide (SiC) surface. <P>SOLUTION: The method for depositing an alumina coating on a component having a silicon carbide (SiC) surface includes a step of depositing a silicon adhesion underlayer 20 on the SiC surface by chemical vapor spraying (a), and a step of depositing coating 30 on the silicon adhesion underlayer 20 by atmospheric thermal spraying (b). A device for measuring deformation is also provided, and the device includes a first alumina coating 30 obtained by atmospheric thermal spraying onto the silicon adhesion underlayer deposited on the silicon carbide layer covering the substrate of the component, a free filament strain gauge 40 placed on the coating 30, and an additional alumina coating obtained by atmospheric thermal spraying onto the strain gauge. <P>COPYRIGHT: (C)2009,JPO&INPIT |
