The results of the surface area measurements are shown in Table 3-3. surface area of the amor-CuTi is 0.13 m2 / g, the surface area of CuTi subjected to heat treatment (773) was found to be unchanged surface area can be subjected to a heat treatment to 0.14 m2 was / g amor-CuTi. surface area of the amor-CuTiHF that the HF treatment in amor-CuTi was increased to 3.7 m2 / g. CuTi (473) HF, CuTi (573) HF, CuTi (673) for each of the surface area with heat treatment temperature rise HF 5.6 m2 / g, 7.9 m2 / g, and increased 11.1 m2 / g. However, CuTi (773) HF, the surface area of the CuTi (873) HF is, 9.7 m2 / g, surface area with 9.1 m2 / g and the heat treatment temperature rise was reduced. Changes in these surface areas, Fig. 3-10, roughness of the surface by a heat treatment temperature before HF treatment can be seen from the SEM photograph of 3-11 is considered to be due to different.
