In the high-temperature gas-solid reaction process of the metal material, an unreasonable sample placement mode can influence the uniformity and stability of the atmosphere on the surface of the sample. For a tubular high-temperature gas-solid reaction heat treatment furnace, the hearth is circular, a common flat plate type sample table is adopted, the sample is not easy to place stably, and the largest sample bearing area is the plane at the diameter of the hearth, so that the sample placement is easy to be limited. If the sample is horizontally placed on a common flat plate type sample table, the number of the placed samples is limited, and the heat treatment efficiency is low; if the sample is horizontally stacked on a common flat-plate sample table or directly stacked in a hearth, insufficient contact between the surface of the sample and the protective atmosphere can be caused, so that the film on the surface of the sample is unevenly prepared.
In addition, if the sample does not have a proper support carrier, the surface of the sample is in direct contact with the inner wall of the hearth and the fire tongs in the sampling and sampling processes, and the inner wall of the hearth and the fire tongs are easy to damage the surface of the sample. In order to avoid the occurrence of the above-mentioned situation, a sample support with reasonable design is required in the heat treatment process, so that the surface of the sample is prevented from being damaged by foreign matters in the whole test process, and the normal gas circulation in the heat treatment furnace is ensured, thereby finally ensuring the heat treatment effect of the sample.

The first loading tray 1 and the second loading tray 2 are kept consistent in shape and size with the hearth of the heat treatment furnace so as to facilitate stable placement of the specimen support in the heat treatment furnace. Because the tubular heat treatment furnace is relatively commonly used, the first sample loading tray 1 and the second sample loading tray 2 of the sample support in this embodiment are designed into circles with the same size, the diameter is slightly smaller than the inner diameter of the hearth, and if the hearth of the heat treatment furnace is other, the two sample loading trays on the sample support can be correspondingly manufactured into other shapes, so that the sample support is applicable to heat treatment furnaces with different hearth styles.
