マグネシヤのマイクロ波接合

抄録

Two magnesia ceramics were joined by the microwave heating method. The joining was easily accomplished in a short time by covering the joining part with a mullite insulating fire brick during microwave irradiation. The bending strength of the joint increased with increasing joining temperature and pressure. The hardness of the joint was higher than that of the matrix. The maximum bending strength of the sample joined at 2150K and 0.5MPa for 4min was 105MPa and was about 70% that of the matrix.
