Figure 2: Photograph of ablation test and morphology of tested sample.

From: Ablation-resistant carbide Zr0.8Ti0.2C0.74B0.26 for oxidizing environments up to 3,000 °C

Figure 2

(a) Green and orange flames are seen in tests of Zr0.8Ti0.2C0.74B0.26 and Zr0.8Ti0.2C, respectively. (b) Comparison of surface of the 30 mm diameter samples before and after ablation. Black-gray sample is before test, and middle and right samples experienced 120 s ablation of 2,000 °C and 2,500 °C, respectively. (c) Surface profile of central region of sample ablated at 3,000 °C, showing the ablated traces (some convexities with the rises of <72 μm) due to evaporations of oxides with low melting points (see Protective mechanisms). But no ablated hollows appeared on surface.
