- FIGS. 1 to 3 The invention will be better understood on reading the non-limiting examples which follow, illustrated by FIGS. 1 to 3 .
- FIGS. 1 to 3 represent in section a porous ceramic body 1 with its coating 2 , respectively for examples 1 to 3 .

- SiAlON is an oxynitride compound of at least the elements Si, Al and N, in particular of a compound respecting one of the following formulas:
- Ceramic Matrix Composite we conventionally mean a product composed of fibers ceramics rigidly bound together by a ceramic matrix.
- ceramic we mean a product that is neither metallic nor organic. In the context of the present invention, an oxide glass and carbon are considered ceramic products.
- coating is meant one or more layers of material (x). At least one of said layers, in particular the layer comprising a compound chosen from alumina, lithium aluminate, an alumina/magnesia spinel, zirconia, preferably stabilized for example by yttrium, hafnia, yttrine .
- This layer may be the result of the reaction of the ceramic body and the deposition by thermal spraying of the particles on the surface of said ceramic body.
- pores refers to all the pores.
- the porosity and the size of the pores of the ceramic body can be determined using a mercury porosimeter in application of Washburn's law mentioned in standard ISO 15901-1.2005 part 1. From a sample of cubic shape of approximately 1 cm 3 , a mercury porosimeter makes it possible to establish a size distribution of the pores by volume, that is to say to determine, for each pore size, a volume occupied by the pores having this size. It is thus possible to determine an equivalent diameter (also called median pore diameter Dso) corresponding to the 50th percentile of the median size of the population of pores of the ceramic body.
- an equivalent diameter also called median pore diameter Dso
- This size divides, in volume, said population into two groups: a group representing 50% of the pore volume and whose pores have a size less than the median size and another group representing 50% of the pore volume and whose pores have a size greater than or equal to said median size.
- the size or diameter of the pores or grains of the coating or the size of the grains of the porous ceramic body are determined by image analysis of cross sections observed under a scanning electron microscope with a magnification at least equal to 1000 , preferably equal to . 2000 .
- the area and the diameter of each of the grains or pores are obtained from the negatives by conventional image analysis techniques, preferably after binarization or segmentation of the image aimed at increasing its contrast.
- a distribution of grain diameters in percentage (in number) or of pores in percentage (in volume) is thus deduced, from which the median diameter of grains or pores corresponding to the percentile Dso is extracted.
- the open porosity of the material measured according to the mercury porosimetry techniques previously described, is approximately 16% (by volume) and its median pore diameter is of the order of 5 micrometers.
- a first series of ten gazettes was preheated to a temperature of 300° C. in an oven before being coated on its inner surface (side and bottom) with an alumina coating by thermal spraying using a Master Jet® type flame gun powered by a bead of Flexicord Pure Alumina® alumina reference 982101147000 supplied by Saint-Gobain Coating solutions.
- the gazettes are placed in an oven at 300°C subjected to a controlled temperature drop at 100°C/h.
- Example 2 unlike the previous example, on a second series of ten gazettes the layer is deposited using a flame gun of the Master Jet® type powered by a Flexicord Alumina Supra ® alumina cord reference 98210 1347000 supplied by Saint-Gobain Coating solutions.
- the gazettes are placed in an oven at 300°C subjected to a controlled temperature drop at 100°C/h.
- a series of ten gazettes is coated on its inner surface (side and bottom) with an alumina coating by thermal spraying using a Proplasma® torch similar to that shown in Figure 1 of EP2407012B1 of WO2014/083544 supplied with an alumina powder.
- the substrate formed by the gazette was preheated to a temperature of 300°C.
- Plasma spraying is done with the axis of the thermal spraying tool normal to the surface by performing translations and slots with overlap. The cooling of the coated gazettes after plasma spraying of the coating is free.
- a fourth example on a series of ten gazettes is deposited an intermediate layer in a manner similar to example 1 then a second layer is deposited by plasma spraying in a manner similar to example 3.
- the cooling of the coated gazettes after plasma spraying of the coating is free.
- the average thickness of the entire coating was determined by scanning electron microscope observation.
- the size of the grains and pores constituting the coating comprises the succession of the following steps, standard in the field:
- a series of 5 SEM shots is taken from the support according to a cross section (that is to say in the entire thickness of a wall). For greater clarity, the shots are made on a polished section of the material. Image acquisition is performed over a cumulative length of coating at least equal to 1.5 cm, in order to obtain values representative of the entire sample.
- the shots are subjected to binarization techniques, well known in image processing techniques, to increase the contrast of the outline of the grains or pores.
- a pore or grain diameter is determined (e), corresponding to the diameter of a perfect disc of the same area as that measured for said grain or said pore (this operation possibly being carried out using dedicated software in particular Visilog® marketed by Noesis).
- a grain or pore size distribution is thus obtained according to a conventional distribution curve and a median size of the grains or pores constituting the coating is thus determined, this median size corresponding respectively to the diameter dividing said distribution into a first population not comprising only grains with a diameter greater than or equal to this median size and a second population comprising only grains or pores with a diameter less than this median size or this median diameter.
- the measurements were carried out by image analysis of the set of the two layers constituting the coating.
- the corrosion resistance of the coating by lithium was evaluated for each example by the following method: A powder of lithium hydroxide with a purity of >99.9% by mass of LiOH was placed in a gazette provided with the coating. The assembly is then placed in an electric oven under vacuum at a temperature of 900°C maintained for 8 hours (rise to 900°C at a rate equal to 500°C/h, natural descent to ambient temperature by thermal inertia of the oven After 5 cycles, the presence of lithium penetration is observed by image analysis using the same method as for the average coating thickness:
- the resistance is excellent if there is no trace of lithium penetration deeper than 20 micrometers in the thickness of the coating; the resistance is considered good for a penetration depth between 20 and less than 30 micrometers;
- the resistance is considered average for a penetration depth greater than 30 and less than 50 micrometers
- the resistance to thermal shock of the gazette was determined according to the following method: A sample of five gazettes previously dried at 110° C. is placed in an oven then heated to 900° C. according to a ramp of 250° C./h. The oven is then maintained at this temperature for one hour. Each gazette is then quickly removed from the oven to undergo quenching in ambient air (20° C.) for 20 minutes. The operation continues in this way until ten cycles have been completed. Each gazette is then analyzed for external and internal observation of the microstructure, in particular of the coating. Observation with the naked eye makes it easy to identify the appearance of external cracks. In particular, very good resistance to thermal shock corresponds to an absence of cracks in the coating or at the interface between the ceramic coating and body. Good resistance to thermal shock corresponds to a localized presence of one or more microcracks, which however do not threaten the integrity of the coating.
- the deposition conditions are specified in Table 1 below.
- the examples according to the invention whose coating has a pore volume fraction greater than or equal to 2 micrometers less than 2.5%, as measured by image analysis, show a satisfactory appearance after deposition, good or even very good resistance to thermal shock and good or even excellent resistance to corrosion, unlike Comparative Example 1.
- the examples according to the invention have little adhesion after baking so that the gazettes are easily cleaned by blowing or scraping without significant deterioration of the coating after 5 lithium corrosion tests.
- Example 4 shows that, in the case of superposition of deposits, the performance of the final coated support still depends on the distinctive criterion cited above.
